TECHNICAL FIELD

This application is directed, in general, to HVAC systems and, more specifically, to a user interface 5 dashboard and installer interface dashboard for a distributed-architecture heating, ventilation and air conditioning (HVAC) network, and methods of use thereof.

BACKGROUND

Climate control systems, also referred to as HVAC 10 systems (the two terms will be used herein interchangeably), are employed to regulate the temperature, humidity and air quality of premises, such as a residence, office, store, warehouse, vehicle, 2625034-1 3 2010201356 14 Jan 2015 trailer, or commercial or entertainment venue. The most basic climate control systems either move air (typically by means of an air handler, or more colloquially, a fan or blower), heat air (typically by means of a furnace) or cool air (typically by means of a compressor-driven refrigerant loop). A thermostat is typically included in the climate control systems to provide some level of automatic temperature control. In its simplest form, a thermostat turns the climate control system on or off as a function of a detected temperature. In a more complex form, a thermostat may take other factors, such as humidity or time, into consideration. Still, however, the operation of a thermostat remains turning the climate control system on or off in an attempt to maintain the temperature of the premises as close as possible to a desired setpoint temperature. Climate control systems as described above have been in wide use since the middle of the twentieth century.

25 DETAILED DESCRIPTION

As stated above, conventional climate control systems have been in wide use since the middle of the twentieth century and have, to date, generally provided adequate temperature management. However, it has been 30 realized that more sophisticated control and data acquisition and processing techniques may be developed 2625034-1 - ίο - 2010201356 06 Apr 2010 and employed to improve the installation, operation and maintenance of climate control systems.

Described herein are various embodiments of an improved climate control, or HVAC, system in which at 5 least multiple components thereof communicate with one another via a data bus. The communication allows identity, capability, status and operational data to be shared among the components. In some embodiments, the communication also allows commands to be given. As a 10 result, the climate control system may be more flexible in terms of the number of different premises in which it may be installed, may be easier for an installer to install and configure, may be easier for a user to operate, may provide superior temperature and/or relative 15 humidity (RH) control, may be more energy efficient, may be easier to diagnose and perhaps able to repair itself, may require fewer, simpler repairs and may have a longer service life. 30 FIG. 1 is a high-level block diagram of an HVAC 20 system, generally designated 100. The HVAC system may be referred to herein simply as "system 100" for brevity. In one embodiment, the system 100 is configured to provide ventilation and therefore includes one or more air handlers 110. In an alternative embodiment, the 25 ventilation includes one or more dampers 115 to control air flow through air ducts (not shown.) Such control may be used in various embodiments in which the system 100 is a zoned system, in the context of a zoned system 100, the one or more dampers 115 may be referred to as zone controllers 115. In an alternative embodiment, the system 100 is configured to provide heating and, therefore, includes one or more furnaces 120, typically associated 2625034-1 - 11 - 2010201356 06 Apr 2010 with the one or more air handlers 110. In an alternative embodiment, the system 100 is configured to provide cooling and, therefore, includes one or more refrigerant evaporator coils 130, typically associated with the one 5 or more air handlers 110. Such embodiment of the system 100 also includes one or more compressors 140 and associated condenser coils 142, which are typically associated in one or more so-called "outdoor units" 144. The one or more compressors 140 and associated condenser 10 coils 142 are typically connected to an associated evaporator coil 130 by a refrigerant line 146. In an alternative embodiment, the system 100 is configured to provide ventilation, heating and cooling, in which case the one or more air handlers 110, furnaces 120 and 15 evaporator coils 13 0 are associated with one or more "indoor units" 148, e.g., basement or attic units.

For convenience in the following discussion, a demand unit 155, sometimes referred to as a unit 155, is representative of the various units exemplified by the 20 air handler 110, furnace 120, and compressor 140, and more generally includes an HVAC component that provides a service in response to control by the control unit 150. The service may be, e.g., heating, cooling, or air circulation. The demand unit 155 may provide more than 25 one service, and if so, one service may be a primary service, and another service may be an ancillary service. For example, for a cooling unit that also circulates air, the primary service may be cooling, and the ancillary service may be air circulation (e.g. by a blower). 30 The demand unit 155 may have a maximum service capacity associated therewith. For example, the furnace 120 may have a maximum heat output (often expressed in 2625034-1 - 12 - 2010201356 06 Apr 2010 terms of British Thermal Units (BTU) or Joules), or a blower may have a maximum airflow capacity (often expressed in terms of cubic feet per minute (CFM) or cubic meters per minute (CMM)). In some cases, the demand 5 unit 155 may be configured to provide a primary or ancillary service in staged portions. For example, blower may have two or more motor speeds, with a CFM value associated with each motor speed.

One or more control units 150 control one or more of 10 the one or more air handlers 110, the one or more furnaces 120 and/or the one or more compressors 140 to regulate the temperature of the premises, at least approximately. In various embodiments to be described, the one or more displays 170 provide additional functions 15 such as operational, diagnostic and status message display and an attractive, visual interface that allows an installer, user or repairman to perform actions with respect to the system 100 more intuitively. Herein, the term "operator" will be used to refer collectively to any 20 of the installer, the user and the repairman unless clarity is served by greater specificity.

One or more separate comfort sensors 160 may be associated with the one or more control units 150 and may also optionally be associated with one or more displays 25 170. The one or more comfort sensors 160 provide environmental data, e.g. temperature and/or humidity, to the one or more control units 150. An individual comfort sensor 160 may be physically located within a same enclosure or housing as the control unit 150. In such 30 cases, the commonly housed comfort sensor 160 may be addressed independently. However, the one or more comfort sensors 160 may be located separately and physically 2625034-1 - 13 - 2010201356 06 Apr 2010 remote from the one or more control units 150. Also, an individual control unit 150 may be physically located within a same enclosure or housing as a display 170. In such embodiments, the commonly housed control unit 150 5 and display 170 may each be addressed independently. However, one or more of the displays 17 0 may be located within the system 100 separately from and/or physically remote to the control units 150. The one or more displays 170 may include a screen such as a liquid crystal display 10 (not shown).

Although not shown in FIG. 1, the HVAC system 100 may include one or more heat pumps in lieu of or in addition to the one or more furnaces 120, and one or more compressors 140. One or more humidifiers or dehumidifiers 15 may be employed to increase or decrease humidity. One or more dampers may be used to modulate air flow through ducts (not shown). Air cleaners and lights may be used to reduce air pollution. Air quality sensors may be used to determine overall air quality. 20 Finally, a data bus 180, which in the illustrated embodiment is a serial bus, couples the one or more air handlers 110, the one or more furnaces 120, the one or more evaporator coils 130, the one or more condenser coils 142 and compressors 140, the one or more control 25 units 150, the one or more remote comfort sensors 160 and the one or more displays 170 such that data may be communicated therebetween or thereamong. As will be understood, the data bus 180 may be advantageously employed to convey one or more alarm messages or one or 30 more diagnostic messages. FIG. 2 is a high-level block diagram of one embodiment of an HVAC data processing and communication 2625034-1 - 14 - 2010201356 06 Apr 2010 network 200 that may be employed in the HVAC system 100 of FIG. 1. One or more air handler controllers ("AHCs") 210 may be associated with the one or more air handlers 110 of FIG. 1. One or more integrated furnace controllers 5 ("IFCs") 220 may be associated with the one or more furnaces 120. One or more damper controller modules 215, also referred to herein as a zone controller module 215, may be associated with the one or more dampers 114 that interface the one or more dampers to the data bus 180. 10 One or more unitary controllers 225 may be associated with one or more evaporator coils 130 and one or more condenser coils 142 and compressors 140 of FIG. 1. The network 200 includes an active subnet controller ("aSC") 230a and an inactive subnet controller ("iSC") 230i. The 15 aSC 230a is responsible for configuring and monitoring the system 100 and for implementation of heating, cooling, air quality, ventilation or any other functional algorithms therein. Two or more aSCs 230a may also be employed to divide the network 200 into subnetworks, or 20 subnets, simplifying network configuration, communication and control. The iSC 230i is a subnet controller that does not actively control the network 200. In some embodiments, the iSC 230i listens to all messages passed over the data bus 180, and updates its internal memory to 25 match that of the aSC 230a. In this manner, the iSC 230i may backup parameters stored by the aSC 230a, and may be used as an active subnet controller if the aSC 230a malfunctions. Typically there is only one aSC 230a in a subnet, but there may be multiple iSCs therein, or no iSC 30 at all. Herein, where the distinction between an active or a passive SC is not germane, the subnet controller is referred to generally as an SC 230. 2625034-1 - 15 - 2010201356 06 Apr 2010 A user interface ("UI") 240 provides a means by which an operator may communicate with the remainder of the network 200. In an alternative embodiment, a user interface/gateway (UI/G) 250 provides a means by which a 5 remote operator or remote equipment may communicate with the remainder of the network 200. Such a remote operator or equipment is referred to generally as a remote entity. A comfort sensor interface 260, referred to herein after simply as a comfort sensor, may provide an interface 10 between the data bus 180 and each of the one or more comfort sensors 160.

Each of the components 210, 220, 225, 230a, 230i, 240, 250, 260 may include a general interface device configured to interface to the data bus 180, as described 15 below. (For ease of description any of the networked components, e.g., the components 210, 220, 225, 230a, 230i, 240, 250, 260, may be referred to generally herein as a device 290. In other words, the device 290 of FIG. 2 is a proxy for any of a furnace, a heat pump, a subnet 20 controller, etc, and that device's associated interface means.) The data bus 180 in some embodiments is implemented using the Bosch CAN (Controller Area Network) specification, revision 2, and may be synonymously referred to herein as a residential serial bus ("RSBus") 25 180. The data bus 180 provides communication between or 30 among the aforementioned elements of the network 200. It should be understood that the use of the term "residential" is nonlimiting; the network 200 may be employed in any premises whatsoever, fixed or mobile. In wireless embodiments, the data bus 180 may be implemented, e.g., using Bluetooth™ or a similar wireless standard. 2625034-1 - 16 - 2010201356 06 Apr 2010

Generally, the network 200 allows for the remote comfort sensors 160, the control unit 150, and user display 170 and/or remote user displays 170 to operate independently as separate logical units, and can be 5 located in separate locations within the network 200.

This is unlike the prior art, wherein these functionalities were required to be located within a single physical and logical structure.

Turning now to FIG. 3A, illustrated is a diagram of 10 a commissioning process 300 of a series of steps that occur in relation to a commissioning of the demand unit 155. The commissioning process 300 includes an enter state 3 01, a device commissioning state 303, and an exit state 305. The HVAC system 100 can be described as being 15 partitioned into a plurality of subnets, each subnet controlled by its own active subnet controller 230.

Device commissioning can generally be defined as setting operational parameters for a device in the network of the HVAC system, including its installation 20 parameters. Generally, the commissioning process 300 is used by the subnet controller 230 when it is active to: a) set operating "Installer Parameters" for a networked device, such as air handlers 110, (henceforth to be referred to collectively, for the sake of convenience, as 25 the demand unit 155, although other devices are also contemplated) , b) to load UI/Gs 240, 250 with names and settings of "Installer Parameters and Features" of the demand units 155, c) to configure replacement parts for the demand units 155, and d) to restore values of 30 "Installer Parameters and Features" in the demand units 155 if those "Parameters and Features" were lost due to memory corruption or any other event. Device 2625034-1 - 17 - 2010201356 06 Apr 2010 commissioning is a process used in the HVAC system 100, either in a "configuration" mode or in a "verification" mode.

In the "configuration" mode, the demand unit 155 5 shares its information with the active subnet controller 230a in an anticipation of being employable in the HVAC system 100, and an appropriate subnet. Generally, the commissioning process 300 provides a convenient way to change or restore functional parameters, both for the 10 active subnet controller 230a and the demand unit 155.

In both the "verification" mode and the "configuration" mode, the demand unit 155 is checked for memory errors or other configuration or programming errors. There are differences in device 290 behavior 15 between the "configuration" mode and in the "verification" mode, to be detailed below.

The "subnet startup" mode programs the subnet controller 230 to be active. The "subnet startup" mode enables subnet communications, (i.e., communication 20 within a subnet), and also deactivates a "link" sub-mode. A "link" mode may be generally defined as a mode that allows a number of subnets to work together on the same HVAC network 200, and that assigns subnet numbers for each subnet to allow this communication. 25 The "installer test" mode is employed when an installer installs and tests aspects and demand units 155 of the HVAC system 100. The "normal operations" mode is an ongoing operation of devices 290 of the HVAC system 100 in a normal use. 30 More specifically, the device commissioning process 300 can be employed with: a) the "configuration" mode, which is invoked when transitioning to the commissioning 2625034-1 - 18 - 2010201356 06 Apr 2010 state 303 from the "subnet startup mode" or "installer test" mode, or the "normal mode" (see below) , or b) a "verification" mode. The "verification" mode is invoked when transitioning to the commissioning state 303 from 5 the "subnet startup" mode.

The following describes an illustrative embodiment of a using the process 300 to commission the demand unit 155, first for a "commission" mode, and then for a "verification" mode. The process of commissioning differs 10 from a "subnet startup," in that commissioning requires that the network configuration, including configuration and activation of subnet controllers 230, has already-been completed before the commissioning process 300 for the device 290 can start. Please note that there can be 15 more than one subnet controller 230 on a subnet, but only one subnet controller 230a is active at any one time. 30

In one embodiment, in order to enter into a state 320 of a state machine 310 (described in detail below with respect to FIG. 3B) in the "configuration" mode, the 20 unit 155 receives either: a) an "aSC" ('active subnet controller') Device Assignment message", having "Assigned State" bits set to "Commissioning"; or b) a receipt of an "aSC Change State" message, with "New aSC State" bits set to "Commissioning," from the active subnet controller 25 230. For both "configuration" and "verification" modes, an "aSC Device Assignment" message can be generally regarded as a message that assigns the unit 155 to a particular active subnet controller 230a. For both "configuration" and "verification" modes, an "aSC Change State" message can be generally regarded as a message that starts and ends employment of the commissioning process 300 for the devices 290. 2625034-1 - 19 - 2010201356 06 Apr 2010

In one embodiment, in the state 320 in the configuration mode, all units 155 respond to the "aSC Device Assignment" message with their respective "Device Status" messages, indicating that the units 155 are now 5 in the commissioning process 300 due to their response to this previous message. For both "configuration" and "verification" modes, the "Device Status" message can be generally defined as a message that informs the active subnet controller 230a of what actions are being taken by 10 the unit 155 at a given time.

However, alternatively in other embodiments, in the state 320 in the "configuration" mode, if the units 155 are instead busy, as indicated by "aSC Acknowledge" bits of the "Device Status" message sent to the active subnet 15 controller 230a set as a "Control Busy," the active subnet controller 230a waits for the busy units 155 to clear their "aSC Acknowledge" bits before proceeding with further elements of the Commissioning process 300. The units 155 then resend their "Device Status" messages as 20 soon as they are no longer busy.

From this point on, all units 155 send their "Device

Status" messages periodically and on any status change, both during and after the commissioning process 300. If the unit 155 does not clear its "aSC Acknowledge" bits 25 within a minute, the active subnet controller 230a sends an "Unresponsive Device2" alarm for each such unit 155.

If in "configuration" mode, the active subnet controller 230a remains in the waiting mode indefinitely, until the unit 155 responds correctly, or the subnet is reset 30 manually or after a timeout is reached. In "verification" mode the active subnet controller 230a proceeds further to exit the state. 2525034-1 - 20 - 2010201356 06 Apr 2010

In the "configuration" mode, each unit 155 remembers all of its optional sensors that are currently attached to it. Furthermore, each unit 155 may store a local copy in its non-volatile memory ("NVM") of any other unit 5 features that it is dependent on. A unit 155 feature can be generally defined as any datum that is fixed and cannot be changed by the installer, serviceman or the home owner. Changing of a "Feature" value normally involves reprogramming of the unit's 155 firmware. 10 In at least some embodiments, a feature is something that is a fixed value, that is hard-wired into a device. In other words, no installer or home owner can change it. Features are programmed into the unit 155 during a manufacturing or an assembly process. Features can be 15 recovered in a home, during a Data non-volatile memory ("NVM") recovery substate of Commissioning state only -the recovery substate happens automatically and without installer or user intervention. In a further embodiment, parameters can be changed by the installers only. In a 20 yet further embodiment, the network 200 of the HVAC system 100 employs "variables" - those can be changed by the installers and also the home owners.

In some embodiments, a "Parameter List" is normally a Feature that contains a special list of specific 25 parameters included in the unit 155. Parameter values can be changed, and their state can be changed also (from enabled to disabled and vice-versa), but their presence is set once and for all in a given firmware version. Therefore, a list of Parameters (not their values) is 30 also fixed, and is thus treated as a "Feature."

However, although elements of the "configuration" mode commissioning and "verification" mode commissioning 2625034-1 - 21 - 2010201356 06 Apr 2010 are similar, when the active subnet controller 230 is in "verification" mode instead of in "configuration" mode, the active subnet controller 230a can exit commissioning process 300 regardless of the value of the alarms of the 5 units 155. However, alternatively, if the active subnet controller 230a is in "configuration" mode, the active subnet controller 230a will not exit from its commissioning process 3 00 for as long as at least one unit's 155 "aSC Acknowledge" flags are set to "Control 10 Busy." In one embodiment of the "verification" mode, the active subnet controller 230a timeouts the installation and resets the subnet to default parameters.

In the "verification" mode, assuming the unit 155 operates with a non-corrupted (original or restored copy) 15 NVM, each unit 155 checks any of its attached sensors to see if they match with the parameters that were present in a most recent configuration of the unit 155. In some embodiments, alarms are generated by the unit 155 for missing or malfunctioning sensors as soon as the faulty 20 condition is detected, to be employed by the user interfaces and gateways present on the subnet to notify the installer or homeowner of the encountered problem. The unexpected absence of certain sensors may inhibit the operation of the unit 155 or the subnet. This is normally 25 manifested by the signaling of the appropriate Service Bits in the Device Status message used by the active subnet controller 230a, to determine the operational viability or health of the subnet's systems.

In some embodiments, the device commissioning 30 process 300 (via the state machine 310) then transitions into a link-mode startup state 330 (FIG. 3B) , and then ends, upon either: a) the last unit 155 receiving all of 2625034-1 - 22 - 2010201356 06 Apr 2010 unit 155 parameters that it is dependent on, when in "verification" mode; or b) upon a request by a user, when in "configuration" mode. The active subnet controller 230 then proceeds to ensure that no subnet unit 155 has its 5 "aSC Acknowledge" flag set to a "Control Busy" state. The "aSC Acknowledge" flag not being set indicates that all of a non-volatile memory of a given unit 155 had been written to with the necessary parameters. If no "Control Busy" state is detected, the active subnet controller 10 23 0a then issues the "aSC Change State" message, which forces the unit 155 from a commissioning state to a noncommissioning state, in either a "configuration" or a "verification" mode.

In some embodiments, when the unit 155 in the 15 process 300 fails its NVM data integrity check in an "NVM Check State," and the active subnet controller is unable to perform NVM Recovery, the unit 155 instead employs its default data stored in its non-volatile (Flash) memory and/or uses default calculations to initialize the data 2 0 dependent on other devices in the system. The other device data to be used for commissioning could have been obtained in either the "verification" or "configuration" mode. For data or other parameters that were not transferred or generated as part of that session of the 25 commissioning process 300, default values are used.

In one embodiment, upon a detection of a system configuration error, such as a missing device whose features or parameters the unit 155 depends upon, it uses the locally stored copy of the other device's features 30 that it depends upon, and ignores any potential feature value conflicts. In another embodiment, the unit 155 uses the locally stored copy of other parameters of the unit 2625034-1 - 23 - 2010201356 06 Apr 2010 155 that it depends on and ignores any potential dependent parameter value conflicts. In other words, the unit 155 employs a first installed parameter as a template for a second installed parameter on a second 5 device. In a third embodiment, the unit 155 will change its parameter or feature values only if explicitly instructed by the active subnet controller 230 or the UI/G 240, 250.

Turning now to FIG. 3B, illustrated is the HVAC 10 device state machine 310 illustrated for a subnet, including the unit 155, in more detail. Solid lines indicate normal state transitions when the subnet is transitioning from one state to another state, dashed lines indicate a subroutine call and red lines, 15 alternating dotted and dashed lines indicate unexpected yet valid transitions. All states other than a state 326 represent device states, and the state 326 represents a message handling routine.

As is illustrated in the present embodiment, a reset 20 state 312 of a subnet advances to a NVR CRC check 316 for a given device (such as unit 155). If the device fails the test, the device advances to a device hard disable 314. If the device passes, however, then in the subnet startup state 320, various features and parameters of the 25 unit 155 are shared with the subnet. Then, in substate 324, device commissioning as described in FIG. 3A occurs. This then leads to an installer test sub-mode 328. This, in turn, then leads to the link mode start-up 33 0, as described above. Finally, then in a step 334, normal 30 system operation occurs, although the system can reset to state 312 or have error messages in the state 326. 2625034-1 - 24 - 2010201356 06 Apr 2010

In a further embodiment, during the NVM CRC check 316, the state machine 310 can advance to a NVM programming state 318. This can occur due to such factors as a failure of a non-volatile memory, or an initial 5 programming of the NVM. In a yet further embodiment, each of these units 155 is programmed to deal with one form of a diagnostic message regarding system errors in the state 326, and from there to testing the device 290 itself in an OEM test mode 332. 10 Turning now to FIG. 3C, illustrated is a state flow diagram 340 for the active subnet controller 230a in relation to the unit 155. Generally, it is the responsibility of the active subnet controller 230a to implement proper state transitions. The other units 155 15 follow the explicit direction of the aSC 230a for all valid transactions. These state diagrams are included to help ensure that a state of the unit 155 is the same as the subnet controller. The aSC 230a is responsible for device synchronization. If the unit 155 is detected out 20 of synch with the rest of the system, the aSC 230a, in some embodiments, immediately tries to bring the unit 155 to the current system state, if possible.

If an addressable unit 155 is detected in subnet startup 344, the active subnet controller 230a applies 25 asynchronous startup rules, which generally pertain to how many parameters are to be passed between device 290 and the active subnet controller 230.

If an addressable unit 155 is detected in commissioning 345, installer test 346, link mode 347 or 30 normal operation 348 substates, the unit 155, in some embodiments, is brought to the current state via a resend message, of an "aSC Change State" message, which involves 2625034-1 - 25 - 2010201356 06 Apr 2010 transitioning from a first current aSC state to a second current aSC state.

In some embodiments, if a unit 155 is detected in the OEM Test mode 332 or a Soft Disabled state 322 (FIG. 5 3B) , the unit 155 shall be reset by the active subnet controller 230a in the step 312. If a unit 155 is detected in "Hard Disabled" or "NVM Programming" state, the active subnet controller 230a assumes that it is not available on the subnet. 10 In a further embodiment, inactive subnet controllers 23Oi are required to keep the most up to date subnet and HVAC system configuration information. Inactive subnet controllers 230i listen to all UI/G and aSC messages and continuously update their non-volatile memory to attempt 15 to be as consistent as possible with the settings stored in active subnet controller 230.

ASPECTS OF INTERFACE FIG. 3D illustrates an exemplary HVAC user interface dashboard ("dashboard") 350 to the user interface 240 to 20 both read and program the active subnet controllers 230a, 23Oi and other elements of the HVAC network 200 of the HVAC system 100. The dashboard 350 can be included within the displays 170.

In the illustrated embodiment, the dashboard 350 25 includes a weather tab 355, an indoor humidity tab 360, an alerts tab 365, a help tab 370, an indoor settings tab 375, a program schedule tab 380, sometimes referred to herein as a programs tab 3 80, a zones tab 385 and a home tab 390, each of which invokes its own corresponding user 30 or installer interface screen or screens. There can be some redundancy of information or functionality between screens corresponding to the different tabs, but each tab 2625034-1 - 26 - 2010201356 06 Apr 2010 includes screens that contain at least some information or functionality that is not found in any other single tab. Furthermore, each tab can be either invoked by a user, such as through touching a tab, or each tab can be 5 invoked remotely, such as by an installer.

Reviewing FIG. 3D with aid of FlGs. 3E-1 and 3E-2, generally, pressing the weather tab 355 advances a user to an exemplary weather screen. The weather screen displays current outdoor weather if a current outdoor 10 temperature and/or humidity is available.

Pressing the exemplary indoor humidity tab 360 advances a user to an indoor humidity screen. The humidity screen allows for the user to change a system dehumidify mode. Dehumidify mode selections include: 15 humidify, dehumidify, humidify and dehumidify and off. A user can cycle through these selections.

The exemplary indoor humidity screen allows a user to view both absolute and relative humidity, and also to set "setpoints" for absolute and relative humidity (i.e., 20 points at which a humidifier or dehumidifier is turned on and off). In one embodiment, relative humidity ("RH") can range from 15% to 45% RH and can be either programmed or humidification on demand. Similarly, dehumidification can be from 40-40% RH and can be either programmed 25 dehumidification or demand.

An indoor humidity screen also allows a user to view humidification and dehumidification comfort zones. In this context, a comfort zone can be generally defined as a zone of a HVAC system that has separate setpoints for 30 temperature and humidity, etc.

Pressing the exemplary alerts tab 365 advances a user to an alerts screen. The alerts screen allows a user 2625034-1 - 27 - 2010201356 06 Apr 2010 to obtain dealer information about currently active alerts and set the dashboard 350 to remind a user later for service alerts. In some embodiments, a select button of the alerts screen of the alerts tab 365 allows the 5 user to obtain a dealer's contact information. The select button allows the user to clear an active alert (all service alerts and specified critical alerts, and also allows the user to clear an active alert (service or critical)). In some embodiments, when a "new 10 service/critical alert" occurs or "remind later" extension time expires, the dashboard 350 floods any current screen with an alert, in other words, the alert overlays any other screen.

An alarm message displays alerts visible to the 15 user, whereas all alerts are visible to the installer.

The installer can learn of these alerts either viewing the alerts tab 365 of the dashboard 350 in person or remotely through a message conveyed through the user interface/gateway 250. 20 Pressing the exemplary help tab 370 advances a user to a help screen. The help screen can include context sensitive help, an option to clear a screen and user system configuration. The context sensitive help presents dialog boxes relating to a current screen's functions, 25 and user system configurations can provide access to all user local settings (i.e., any setting that does not require an installer to make a change, but can instead by made by a user.)

In some embodiments, there can be a time-based 30 notification of consumables in the help screen, either for the user or for an installer. These consumables can include, in some embodiments: media filters, UV bulbs 2625034-1 - 28 - 2010201356 06 Apr 2010 and humidifier pads. All information concerning consumables can be accessible by both the installer as well as the user via the help screen. In some embodiments, a user and installer can enable and manually 5 change the time settings for any timer of the HVAC system 100 through the help screen. Similarly, a maintenance reminder can be accessible by the installer, as well as the user, via the help screen.

Pressing the exemplary indoor settings tab 375 10 advances a user to an indoor settings screen. In one embodiment, the indoor settings screen display indoor temperature measurement and temperature settings. The indoor settings also display the system mode settings and fan mode settings. In one embodiment, system mode 15 selections include: heat, cool, heat and cool, off and emergency heat. Fan mode selections include: automatic, on and circulate. The dashboard 350 allows the user to change the system mode and the fan mode through cycling through various choices . 20 In one embodiment, equipment employed within the system mode dictates which system modes (heat, cool, heat & cool, emergency heat) are visible. For example, a "Heat Sc Cool" selection of the system mode is visible only when both heating equipment and cooling equipment are present 25 in the system. Typically, the system mode selection of "Off" is always visible.

The indoor temperature settings screen also allows a user to change current temperature setpoints, (i.e., points at which a heater or air conditioner is turned on 30 and off) unless this would override a programmed setting, in which case, a hold occurs until an end of the 2625034-1 - 29 - 2010201356 06 Apr 2010 programmed time occurs and the new setpoints become the operating values of the HVAC system 100.

The exemplary dashboard 350 also allows its system mode settings and fan mode settings to be obtained and 5 changed via RSBus devices (e.g. User Interface/Gateway 250 coupled to the bus 180) remotely. If the dashboard 350 is requested, remotely or locally, to change the system mode to an invalid setting, the system mode is not changed. 10 Furthermore, the indoor settings tab 375 allows for a user/installer to view all system information and comfort settings (i.e., temperature and humidity) and allow editing of all current settings, as well as fan mode settings. The indoor settings tab 375 allows the 15 fan mode (on, auto, circulate) to be obtained and changed via the RSBus (e.g., via bus 180 and user interface/gateway 250.)

Pressing the exemplary programs tab 380 advances a user to a programs schedule screen. The programs schedule 20 screen allows for viewing/editing/enabling future program schedule events (e.g., temperature setpoints, system modes and fan modes) in the HVAC system 100. The programs screen allows a programming of event times, temperature setpoints and fan mode for each pre-defined period. A 25 program schedule does not run when the system mode is set to "off."

In one embodiment, the programs screen is seven-day programmable with the ability to select multiple days for programming. In one embodiment, the programs screen is 3 0 capable of programming up to four (4) events per 24-hour period. In one embodiment, program schedules for temperature setpoints are programmed for a seven day 2625034-1 - 30 - 2010201356 06 Apr 2010 schedule, up to four periods per day and are stored in non-volatile memory. In one embodiment, program schedule events can be set in 15-minute increments of time. The scheduled events execute in order based on time of day. 5 In one embodiment, the user interface 240 provides the capability to enable/disable any period of any given day by pressing the corresponding time button for two seconds.

Generally, if a mode changes, such as a fan mode 10 change, is made within the program schedule screen is made while a program schedule of the programs tab 380 is actively executing, a program schedule "hold" mode is invoked until a next program schedule event, at which time the new setpoint is acted upon. If a temperature 15 setpoint change is made while the program schedule of the programs tab 380 is not active, the dashboard 350 updates the display with the new setpoint and acts upon this new setpoint.

Generally, the exemplary dashboard 350 allows its 20 programmed temperature setpoints (heat, cool) and modes to be obtained/changed via RSBus devices (e.g. User Interface/Gateway 250 over the bus 180) remotely. If the dashboard 350 is requested (remotely or locally) to change either setpoint, either temperature or humidity, 25 to a setting beyond the setpoint limits, the setpoint is not changed. If the dashboard 350 is requested remotely or locally to change the fan mode or system mode to an invalid setting, the fan mode or system mode is not changed. 3 0 In some embodiments, the cooling setpoint is shown only when cooling equipment is present in the system.

Likewise, the heating setpoint is shown only when heating 2625034-1 - 31 - 2010201356 06 Apr 2010 equipment is present in the system. The dashboard 350 may not allow two program scheduled events to begin at the same time. In other words, there can be only one setpoint for either a humidity or a temperature for a given time 5 period - one for each.

In one embodiment, up and down arrows of a program screens of the programs tab 380 allows the user to edit a selected box information. A save button allows the user to save changes to the program schedule. A cancel button 10 allows the user to quit the program schedule edit screen without saving changes. A back button returns the user to the program schedule day selection screen. (Not illustrated.)

In some embodiments, pressing the zones tab 385 15 advances a user to a zone screen which, in one

embodiment, is accessible only by an installer with a proper key. Generally, the zone screen deals with information that is pertinent to programming HVAC equipment for various environmental "zones" within the 20 HVAC system (e.g., living room, bedroom, kitchen, etc.)

The zone screen therefore advises the user to contact the manufacture for more information regarding the zone screen. The zones tab 385 then either advances to a home screen of the programs tab 380 or back to the overall 25 user dashboard 350.

Generally, the home screen of the home tab 390 includes a summary of indoor environmental conditions for a user. A home screen indicates a status of the program schedule (ON, OFF). The home screen indicates temperature 30 control status (heating, cooling, off, waiting) as well as humidity control (humidifying, dehumidifying, waiting) of the HVAC system 100. In one embodiment, when a given 2625034-1 - 32 - 2010201356 06 Apr 2010 system is set to "off," only "system is off" is displayed in the home screen.

In some embodiments, the dashboard 350 returns to the home screen after 30 seconds has elapsed since a last 5 screen or tab press, including from any other tab of the dashboard 350. In some embodiments, after a 30 second period of inactivity, any changes made to a screen requiring an active "set" or "save" button press are lost. The dashboard 350 instead returns to the home 10 screen. In some further embodiments, after a user- selectable time period of inactivity, an initial screen press, even upon a tab, causes only a backlight to activate with the home screen as the initial screen shown. The home tab 390 can include a series of screens 15 that are navigable from the home screen via an icon press .

Although not illustrated in FIG. 3D, an installer dashboard including installer screens can also be accessed through the home screen by an installer with a 20 proper key. Generally, the installer screens allow for an installation and configuration of various pieces of equipment in the HVAC system 100. The installer screens can also enable various default values as parameters of operation. 25 In some embodiments, when a button of a screen of the dashboard 350 is held, the dashboard 350 initially displays an update to the value being changed at a rate of change of 0.5 seconds. After a button hold of 3 seconds, the rate of change is increased to 0.25 seconds. 30 The user dashboard 350 can itself be a color and touch-screen. The dashboard 350 can include a dynamic full color dot matrix LCD display. A touch pad may be 2625034-1 - 33 - 2010201356 06 Apr 2010 built into/over the dashboard 350. Typically, a maximum delay between any key press and display feedback (indication by selected button, screen change, etc.) is 0.2 seconds . 5 FIG. 4 illustrates a high-level flow diagram 400 of exemplary transitions, for both user and installer, between user interface screens corresponding to various tabs of the exemplary dashboard of FIG. 3D and various exemplary interface screens of an interface dashboard of 10 FIGS. 11A1 and 11A2.

The exemplary flow 400 has an installer screen flow 401 and a user screen flow 451. The installer screen flow 401 of the dashboard 350 provides access to all installer screens (including subnet start up, configuration, 15 commissioning, installer tests, alerts and diagnostics). The screens of the user screen flow 451 are accessible through the tabs 355-390 of FIG. 3D, with the exception of a new alert screen 452, which the dashboard 3 50 generates upon a new alert. In a further embodiment, the 20 dashboard 350 allows each screen of the flow 400 to be invoked remotely by a user and/or installer via the User Interface/Gateway 250.

Upon power-up of the HVAC system 100, an installation tab 402 of the installer flow 401 appears. 25 Unless an installer inputs a correct key code within a given time period, the flow 400 transitions to a home screen 450. However, if the installer inputs the correct key, an installer screen corresponding to the installer test tab 404 appears. The installer can then install and 30 configure various devices in the HVAC system 100. After installation, the installer flow 401 then advances to the home screen 450. 2625034-1 - 34 - 2010201356 06 Apr 2010

In one embodiment, the installer flow 401 includes a series of screens that are accessible from the home screen 450 via both a) an icon press; and then b) a correct entry of a correct key sequence. In one 5 embodiment, pressing a dealer logo, such as a "Lennox™" logo, on the home screen 450 for 5 seconds allows an installer to execute system startup processes, as well as view/edit the alerts and diagnostics via the installer configuration screens of the flow 401. 10 Generally, the home screen 450 provides a high level overview of the current indoor conditions. The home screen 450, in some embodiments, displays the indoor temperature, indoor relative humidity status, outdoor temperature and system status (e.g. heating, cooling, 15 off, humidifying, dehumidifying, etc.) of the HVAC system 100.

From the home screen 450, a warning screen 412 for an installer can be generated by the dashboard 350. This warning screen 412 can be conveyed to an installer either 20 directly when installer is present, or through a remote communication, such as over the bus 180 through gateway 250, and then perhaps through the Internet to the installer. The warning screen 412 generally states that there is a type of problem that should be addressed by an 25 installer, but may not give all details. Once the warning screen 412 is acknowledged by an installer, an alerts tab 408 has a screen that is the default screen for the dashboard 350.

From the warning screen 412, the installer can also 30 advance to either a diagnostics screen of a diagnostics tab 406, a contextual help screen of the installer help tab 414, the installer screen of the installation setup 2625034-1 - 35 - 2010201356 06 Apr 2010 tab 402, or an installer screen of the installer test tab 404.

In some embodiments, for a user, from the home screen 450, the new alert screen 452 can arise upon a 5 first detection by the HVAC system 100 of an alert. Similarly, the alerts tab 365 can be used to invoke and view an alerts screen. In one embodiment, the alerts tab 365 can be used to access every other tab in the dashboard 3 5 0. 10 In the illustrated exemplary flow 400, the home screen 450 transitions to either the alerts tab 365 if an active alert exists or the indoor settings tab 375. From the indoor settings tab 375, all other user tabs are also accessible. These include the weather tab 355, the indoor 15 humidity tab 360, the alerts tab 365, the help tab 370, the programs tab 380 and the zones tab 385. Please note that, in some embodiments, the zones tab 385 can transition to the home screen 450, and the zones of the zones tab 385 are typically set by an installer of the 20 HVAC system 100.

Regarding the alerts screen 452, in one embodiment, if the dashboard 350 is displaying a popup alert at the time when another alert (to be displayed to the user) occurs, the dashboard 350 continues to display the 25 current alert screen 452. When a current alert has been addressed, the dashboard then overwrites the screen with the newest alert. If multiple popup alerts exist simultaneously, the dashboard 350 displays each (in order of occurrence - timestamp) one-by-one after the previous 30 new alert is addressed. There is not a time-out for a new alert flooding the screen. The new alert remains on the 2625034-1 - 36 - 2010201356 06 Apr 2010 screen of the dashboard 350 until addressed by the user/installer.

Turning briefly now to FIG. 5, illustrated are exemplary corresponding screens of the tabs of FIGs. 3D 5 and 4 illustrated in more detail. The weather tab 355 can display weather info when available. The indoor humidity tab 360 enables a user to set humidity modes and setpoints. The alerts tab 365 can display alert info. The home screen 450 can interact with the other illustrated 10 tabs. The indoor settings tab 375 can set display and set temperature conditions and settings (setpoints), overall system mode and fan mode. The programs tab 380 enables a user to program various times. The zones tab 385 forwards an admonition to the user to request more information 15 from the manufacturer, and then transfers back to the home screen 450.

Generally, FIGs. 5A through 5D-2, to be discussed below, illustrate aspects of the present disclosure that are applicable to at least some, and can be to all, of 20 the user screens of FIG. 3D and FIG. 4.

Turning now to FIG. 5A, illustrated is an embodiment of the screen 500 of the dashboard 350 that bolds a selected item 501, 503, 505, 507 relative to other selected items in a list in the dashboard 350. The user 25 can highlight a selected item in white; the other selected items are in grey.

Turning now to FIG. 5B, illustrated is an embodiment of an unlocked screen mode 521, a partially locked screen mode 523, and a fully locked screen mode 525 of the 30 dashboard 350. The partially locked screen mode 523 places a lock-pad icon 526 over a text 524 that states "press for more," and also deactivates all buttons except 2625034-1 - 37 - 2010201356 06 Apr 2010 up-down arrows 529. Partially locked mode has a limited functionality.

In one embodiment, the fully locked mode 525 deactivates all buttons and removes the up/down arrows 5 from a screen. To unlock the partially locked screen mode 523 or the fully locked screen mode 525, a user presses and holds the lock-pad icon 526 for a selected period of time, such as five seconds. In one embodiment, the fully locked screen mode 525 can also occur due to a passage of 10 a pre-selected amount of time. The partially locked screen mode 523 or the fully locked screen mode 525 can display control parameters for an extended period of time.

Turning to FIG. 5C, illustrated is an exemplary 15 screen 530 of the dashboard 350 illustrating a display of discovered equipment in the HVAC system 100. Generally, in prior art interfaces, a text list is used to inform a user/installer about found communicating devices in an HVAC system. However, in FIG. 5C, icons or pictures of 20 equipment 531-535 are used instead to help a user/installer understand what devices and/or equipment is connected to the HVAC system 100. In the exemplary screen of FIG. 5C, each of the discovered devices or equipment 531-535 has a graphical user interface ("GUI") 25 for employment by the installer, although other tabs of the dashboard 350 can also employ icons for found or discovered equipment.

Turning now to FIG. 5D-1, illustrated is an exemplary embodiment of a dashboard 350 having a lighting 30 system 551 including a) a screen 555 that needs a backlight to display information to b) a backlight 557 and c) a motion detector 559, wherein the backlight is 2625034-1 - 38 - 2010201356 06 Apr 2010 turned on by the motion detector 559 upon a detection of motion within a selected range. The screen 555 can be an LCD screen.

Generally, the lighting system 551 allows a user to 5 view indoor settings, without having to touch a button on the dashboard 350, through employment of the sensor 559 and the backlight 557. With one embodiment of the system 551, a home owner can view indoor settings when passing by a dashboard 350, which activates the sensor 559 which 10 then turns-on the backlight. This allows a viewer to view settings of the dashboard, although indoor, from a distance, as determined by the sensor 559. This can make for a convenient way for a user to view indoor settings when the backlight 557 is initially off, as it is 15 switched on by the motion detector 559. Furthermore, the system 551 can conserve energy and screen 555 life when the backlight 557 is not on.

When the exemplary dashboard 350 is not being actively engaged by the user (i.e., not being touched 20 through a touch-screen interface and no motion has been detected by the motion detector 559), the backlight 557 is off. The screen 555 is then perceived as substantially dark 560, and no information can be read by a user, as is illustrated in FIG. 5D-2. 25 In the system 551, the motion detector 559 detects movement within a specified distance of the dashboard 350 and commands the backlight 557 to turn on, but otherwise does not allow the backlight 557 to turn on if no motion is detected. For example, in FIG. 5D-3, the backlight is 3 0 off because no movement, such as of a user 562, is detected within a movement detection zone 561, and the screen is dark 560. 2625034-1 - 39 - 2010201356 06 Apr 2010

However, once the movement is detected in the movement detection zone 561 by the motion detector 559, such as a movement of the user 562, then the dashboard 350 turns on the backlight 557 so that information can be 5 read from the screen 555 of the dashboard 350, such as illustrated in FIG. 5D-4. The user 562 may, therefore, be able to read the dashboard 350 data on the screen 555 without having to walk up to the dashboard and touch the screen of the dashboard. This can also allow the user 562 10 to press the dashboard 350 one less time, which can prolong a touch-screen life of the dashboard 350. When the user 562 walks close enough to the motion detector 559 for the motion detector 559 to detect the user's movement within the movement detection zone 561, then the 15 backlight 557 turns on and all buttons and tabs of the dashboard 350 are enabled. However, when the user 562 is out of range of the detection range 561, the system 551 again disables the backlight 557 and the various tabs, buttons, etc., and the screen is typically again dark 20 560, as illustrated in FIG. 5D-2.

Turning now to FIG. 5E, illustrated is an exemplary flow of screens 570 of the dashboard 350. In the exemplary flow, an installer selects an item of the screen 570 of an installer screen through an employment 25 of text 563, which itself can be a button to select the text. In other flows, the text can be used in other screens of the dashboard 350.

In a further embodiment, the dashboard 350 has a screensaver that activates after a selected amount of 30 inactivity from a user. In this embodiment, the dashboard 350 allows a user to download an image for the dashboard 350 to display when it is idle. Thus, the dashboard 350 2625034-1 - 40 - 2010201356 06 Apr 2010 can become an equivalent of a digital photo-frame when its controls are not active. In one embodiment, through pressing anywhere on a touch-screen of the dashboard 350 dismisses the screensaver image and re-displays the 5 dashboard 350 controls.

Turning now to FIG 6A, an exemplary humidity graphic 601 can be used to set humidify and de-humidify setpoints. In humidity screens 617, 619 of the humidity

tab 360, a humidity status and RH humidity are both 10 displayed on a same screen of the humidity tab 360. Generally, a user may not understand what XX% of humidity denotes on his or her dashboard 350. Therefore, this embodiment of the screens 617, 619 both displays the RH and also interprets the RH. 15 in a further embodiment, below 36% the humidity graphic 601 reads "INDOOR RH XX%- DRY," actual values can be between 35%-37%. Above 49%, the humidity graphic 601 reads "INDOOR RHXX%" - HUMID., actual value can be between 48% and 50%. Between 36% and 49% RH, the display 20 reads "INDOOR RH XX% - NORMAL" or "INDOOR RH XX% OK", actual values can be between 35% and 50%.

An exemplary indoor humidity graphic shows a single bar 602 with relative humidity ("RH") being a calibrated item. A left side 603 of the bar 602 displays a current 25 indoor RH level with the use of a triangle 605, and a right side 604 uses a triangle 607 to show a current humidify or dehumidify setpoint . Two up/down arrows 608 adjust a humidity setpoint, and a switch button 613 transitions the humidity graphic 601 to display either 30 humidify comfort range setpoint or a de-humidify comfort range setpoint. In other words, the humidity graphic 601 2625034-1 - 41 - 2010201356 06 Apr 2010 can transition from the humidity screen 617 to a dehumidify screen 619.

Turning now to FlGs. 6B-1 through 6B-4, illustrated is an employment of one a plurality of exemplary screens 5 631 of a humidity tab 360 of FIG. 3D that is dependent upon equipment installed in the HVAC system 100 of FIG. 1. In other words, if a given piece of equipment is not installed in the HVAC system 100, an indicia of that piece of equipment is not illustrated on the humidity 10 screen of the humidity tab 360.

For example, the indoor humidity tab 360 can be dependent on humidifiers and cooling equipment. Without cooling, equipment, de-humidification is not an option. Furthermore, the indoor settings tab 375 is dependent on 15 heating and cooling equipment, and so is the programs tab 380. Therefore, the dashboard 350 removes modes, system setting options, and control setpoints (humidity and temperature) based upon which pieces of equipment to be discovered during an "installation and set-up process" 20 are not actually discovered. Therefore, if a given piece of humidification or dehumidification equipment is not present, it may not be displayed in the screens 631.

For example, FIG. 6B-1 shows an indoor humidity screen 633a, an indoor setting screen 633b, a programs 25 summary screen 633c and a programs input screen 633d with all options and services available. FIG. 6B-2 shows equivalent screens, here designated 635a-635d, based on only heating equipment and a humidifier being installed. FIG. 6B-3 shows equivalent screens, here designated 637a- 30 637d, based on only cooling equipment being installed, without a humidifier. Finally, FIG. 6B-4 shows the indoor humidity screen, here designated 639, for which only 2625034-1 - 42 - 2010201356 06 Apr 2010 heating equipment is installed, without a humidifier. As is illustrated, equipment that is not available is not illustrated. In further embodiments, interface screens correlating to indoor settings tab 375 and programs tab 5 380 do not display indicia of devices not installed in the HVAC system 100, either.

In a further embodiment, the humidity tab 360 allows users to have and configure different humidity levels during different periods of a day. These periods could be 10 a wake, leave, return and sleep period, for example. For an exemplary instance of use, a user can have 40% humidity level in the morning, and 45% humidity level at night in the same day. Additionally, users can have different humidity levels for different days or group of 15 days. Some parts of the country can have changes in its humidity level throughout the day, so therefore users who reside in these areas can maintain their comfort inside of their homes by using this feature.

Turning now to FIGs. 7Ai through 7Aiv and FIGs. 7Bi 20 through 7Biv, illustrated are an exemplary flows of various transitions of a help screen having a help tab 37 0 of the dashboard 350 that are dependent upon or otherwise determined at least in part by a screen displayed before the help tab 370 is activated. 25 Generally, a purpose of interactive help for the HVAC system 100 is for a user or installer to navigate throughout the dashboard 350 without the user or installer having to go find a manual and look up a particular function or dashboard 350 screen shot. 30 Discussed below are an exemplary flow 710 and a flow 750, both to help accomplish this goal of navigation. 2625034-1 - 43 - 2010201356 06 Apr 2010 FIGs. 7Ai through 7Aiv; collectively referred to as FlGs. 7A corresponds to an example flow 710. FIGs. 7Bi though 7Biv, collectively referred to as FIGs. 7B, corresponds to an example flow 750, Both the flows 710, 5 750 allow a user to get help on current dashboard screens without changing his or her current dashboard 350 settings. A help interface can therefore be located in the dashboard 350, and the user/installer does not necessarily have to find or use an independent manual. 10 An approach of the exemplary flow 710 of Figs. 7A is directed towards dependent settings for help screen sequences. The flow 710 illustrates help screens that progress in a predetermined sequence depending on the screen shown before the help tab 370 is pressed. 15 Generally, help is supposed to teach a user and not confuse them more; therefore, help in the flow 710 does not display information about possible settings that were not displayed on the screen before the help tab was pressed. 20 For example, the exemplary flow 710 displays 3 different screens 711 (FIG. 7Ai), 712 (FIG. 7Aii), 713 (FIG. 7Aiii) that could be displayed to a user before a help tab 370 is pressed. After the help tab 370 is pressed, the screen transitions as follows: the screen 25 711 transitions to a screen 714 (FIG. 7Ai); the screen 712 transitions to a screen 715 (FIG. 7Aii) ; and the screen 713 transitions to a screen 716 (FIG. 7Aiii). Thus, each screen 711, 712, 713 progresses to its corresponding particular screen 714, 715, 716, 30 respectively, that contains information specific to the screen transitioned from. The help screens 714, 715, 716 each contain a text box and arrows that give information 2625034-1 - 44 - 2010201356 06 Apr 2010 about a particular area of the screen that was present before the help was invoked.

Pressing anywhere on a help screen 714, 715, 716 transitions the help screen to a screen 717 (FIG. 7Aiv). 5 This particular screen 717 is used for all the screens 711, 712, 713, because the screen 717 row C provides information about a common item for all the screens 711, 712, 713.

Touching the screen 717 transitions to a screen 718, 10 (FIG. 7Aiv). This is yet another screen that displays common information for all the screens 711, 712, 713. A screen 718 (FIG. 7Aiv) is the last screen in the help sequence 710. Pressing the screen 717 of the dashboard 350 transitions back to the screen displayed before the 15 help tab 370 was pressed, via a step 720.

Turning now in a further embodiment to FIGs. 7Bi through 7Biv, collectively referred to as FIGs. 7B, help screens of the help tab 370 allows a user to adjust settings on a help screen without saving changes to the 20 settings to the HVAC system 100. Generally, once the user exits a help screen, all the settings or screen changes return to their previous state before the help tab 370 was pressed, which allows a user to experiment with settings of a screen without saving them to the HVAC 25 system 100.

An exemplary screen 751 of the flow 750 of FIGs. 7B is the screen displayed on the dashboard before a help tab 370 press. A screen 752 is the screen displayed immediately after a help tab 370 is pressed. A difference 30 between screen 751 and 752 of flow 750 is a text box.

The text box on screen 752 gives a brief explanation about a current screen, and tells the user to touch an 2625034-1 - 45 - 2010201356 06 Apr 2010 area of interest to get more information. Assuming that a user wants to know more about "current temp" and pressed in this area, for example, then the screen progresses to a screen 753 (FIG. 7Bii) with a new text box listing 5 information about "current temp." A screen 754 is shown after the "fan setting" area is touched. However, this area of the screen contains a select button. In one embodiment, pressing the select button changes the screen to a screen 755 (FIG. 7Biii) 10 with a new text box listing information about the new setting. The transition from the screen 754 to the screen 755 not only shows a new text box, but it also changes the highlighted setting from "on" to "circulate." In one embodiment, the screen 755 transitions to a screen 756 15 (FIG. 7Biii) if the system setting area is pressed. In one embodiment the screen 756 transitions to a screen 757 (FIG. 7Biv) if the select button is pressed. However, the screen 757 transitions back to the screen 751 of FIG. 7Bi, the screen displayed on the dashboard before the 20 help tab 370 press.

Turning now to FIGs. 8A-8D, illustrated are various views of a screen 831 dependent upon equipment being found in the HVAC system 100 of FIG. 1, as discussed regarding the screens 631 of FIGs. 6B-1 through 6B-4, 25 above. In FIG. 8A-8C, a screen 83*a is an indoor humidity screen, a screen 83 *b is an indoor settings screen, a screen 83*c is a program summary screen, and a screen 83*d is a program input screen.

Regarding FIG. 8A, screens 833a-833d show the screen 30 831 all options and services available. In FIG. 8B, screens 835a-835d illustrate the screen 831 for the case in which no cooling equipment is installed. In FIG. 8C, 2625034-1 - 46 - 2010201356 06 Apr 2010 screens 837a-837d illustrate the screen 831 for the case in which no heating equipment is installed. And FIG. 8D illustrates an indoor humidity screen 839 reflecting the case in which heating equipment is installed but no 5 humidifier is installed. As is illustrated, equipment that is not available is not shown in the screen 831.

Turning to FIG. 9A, illustrated is an exemplary programs screen 910 of the programs tab 380 that displays all program time periods and programmed temperature 10 setpoints for the programs tab 380. In this embodiment, all program schedule setpoints 912, 914, 916, 918 are displayed on one programs screen 910. All time periods for a program schedule are displayed as well. In the illustrated embodiment of the screen 910 of the programs 15 tab 380, time is listed first, then heat temperature, cool temperature, and fan settings are last. The screen 910 can be a 4x4 matrix with only one setpoint area/button being selectable at a time. In one embodiment, once a setpoint area is touched, the box 20 turns an inverse of its current color. In the illustrated embodiment, up/down arrows 921 are used to adjust each setpoint/setting.

Turning now to FIG. 9B-1 and 9B-2, illustrated is an exemplary flow 930 of programs screens. The screens of 25 the programs tab 380 include buttons 933 that turn an inverse color as a selection and touch reaction. For example, FIG. 9B-1 illustrates a programs screen 932 with a particular button 933 not being touched. A programs screen 934 illustrates the case that a button 935 being 30 touched, and turning an inverse color. In FIG. 9B-2, a screen 936 illustrates the button 935 staying an inverse color, and an arrow button 937 turning an inverse color. 2625034-1 -ΑΙ 2010201356 06 Apr 2010 Α screen 938 illustrates that the button 935 stays the inverse color, but an arrow button 939 reverts to its previous color.

In one embodiment, any touched button of the buttons 5 933 of the flow 930 turns an inverse color while being touched. If the button could be adjusted to another value, then the button/selection box remains inverted as to color even when the user is no longer touching the button, such as the button 935. However, if the button 10 is an up/down arrow, for example the button 937, then the button only turns inverse while the user is touching that button. In other words, when the user releases the button, such as an up/down button, then the button returns to its normal color/state, as illustrated by the 15 button 939. In other embodiments, the button color inverse can occur in other tabs, such as the home tab, the humidity tab, and so on.

Turning now to FIG. 9C, illustrated is a program schedule in a programs screen 940 of the programs tab 380 20 partitioned into a plurality of time zones wherein, upon a button corresponding to a time zone 941 being pressed for a set period of time: a) a temperature setpoint for that time period is deactivated, b) a display of the deactivated setpoints of the deactivated time period now 25 appears dim relative to a display of the time period's setpoints before deactivation; and c) the deactivated time period's setpoints 943 appear dimmer relative to an active time period's setpoints.

In the illustrated embodiment of FIG. 9C, if one of 30 the time zones 941 is pressed and held for approximately two seconds, then the setpoints for that time period 943 2525034-1 - 48 - 2010201356 06 Apr 2010 is deactivated. In one embodiment, the time period 943 is then controlled by the previous time period's setpoints.

Turning now to FIG. 9D-1, illustrated is an interface 950 for setting a system time for an HVAC 5 system 100, such as through a programs screen of the programs tab 380. Setting a system time involves 6 boxes. Each box contains a particular aspect of time and date. Only one box can be changed by a user at a time. FIG. 9D-1 generally discloses an analog clock interface 950 with 10 date and time selection boxes. The date and time selection boxes are as follows: hour box 961, minute box 962, AM/PM box 963, month box 964, day box 965 and year box 966.

Generally, in the clock interface 950, the hands 15 958, 959 of the clock interface 950 are moved by touching them and dragging them to a desired position, either through a touch screen or with a device such as a trackball. The hour hand 958 and the minute hand 959 are linked to their corresponding boxes 961, 962, and the 20 boxes 961, 962 change if their corresponding hands are adjusted. For example, if the hour hand 958 is changed from "12" to "6," then the hour box 961 changes from "12" to "6." The up and down arrows 960 can also be used to adjust each interface box. Typically, in the interface 25 950, at least one value of at least one interface box is changed as a user drags at least one clock hand of the analog clock. Generally, in the interface 950, at least one value of at least one number itself is used as an input to a box, and the analog clock face maps to the 30 changed value.

Turning now to the clock interface 965 of FIG. 9D-2, the clock face numbers themselves are used as buttons, a 2625034-1 - 49 - 2010201356 06 Apr 2010 selection of any of which define where clock hands 973, 974 point and values in boxes 971, 972, Either the hour 971 or minute 972 box is selected, and then the desired number on the clock face is pressed, upon which both the 5 hour hand 973 or minute hand 974 jump to that setting, and boxes 971, 972 fill in for that value. For example, if the hour box 971 is selected and the current setting is "5," and then the clock face number "10" is pressed, then both the hour hand 973 jumps to "10" and the hour 10 box 971 adjusts to "10." The up and down arrows 960 can be used to adjust each box.

Turning now to FIG. 9E, illustrated is an embodiment of a programs screen of the programs tab 380 and a reset interface 975 for the same. Generally, the reset 15 interface 975 of FIG. 9E can help a user reset to predetermined default setting, such as a factory setting 976 or another custom setting 977, when a user inadvertently changes one or more settings, or otherwise wishes to go back to these settings. Without the reset 20 interface 975, a user might have to spend a considerable amount of time reviewing an owner manual and/or scrolling through a plurality of menus to locate the erroneous or unwanted settings, and may not know what the reset settings even are. As is illustrated, there are different 25 selections for settings, temperature, clock, daylight savings time, display and backlight.

All buttons in FIG. 9E that are in grey represent an exemplary set of employed reset values or parameters as currently selected in the illustrated exemplary reset 30 interface 975 upon an exit from the reset interface 975. These reset selections are employed by the HVAC system 100. These reset values over-ride whatever is currently 2625034-1 - 50 - 2010201356 06 Apr 2010 being employed in the HVAC system 100. However, any reset value may be changed, as described below.

Generally, the reset interface 975 can select from a default value among the following values: a user can 5 reset the dashboard 350 to the factory setting 976 or to another value, such as the custom value 977 programmed by an installer. For example, if programming or operating becomes confusing or other issues occur, the customer can reset the values to these prior settings. The reset 10 screen 975 provides a reset unit of measurement in either the British unit (Fahrenheit) 978 or a S.I. 979 unit (Celsius).

The user may select a reset to a 12 hour 980 or 24 hour 981 clock. If users prefer the 24 hour clock rather 15 than the "12" hour clock, he or she can do so via this change. The user can also adjust or correct the time, for any reason, including daylight savings times 982, 983. A user may also set the default language: the consumer or dealer can reset to an exemplary preferred 20 language 984-987 or change it, if needed. The customer can reset the backlight brightness, such as backlighting for high 991, medium 990, low 989, or off 988.

Generally, when the installer first installs the equipment, the installer will be able to set all 25 parameters outlined above as part of the initial set up and commissioning of the dashboard and system. An installer or user can save the settings through a save button 992, or exit with an exit button 993. When the settings are saved, this over-rides any other programming 30 or configuration in the HVAC system 100.

Turning now to FIG. 9F, illustrated is an exemplary programs screen that further includes a display of a 2625034-1 - 51 - 2010201356 06 Apr 2010 plurality of pre-populated program schedule settings. The pre-populated program settings selection choices range from a maximum comfort 994 to a maximum energy savings 998 of the range. The settings employ a slider 992 5 between the maximum comfort setting 994 to the maximum energy savings 998 of the selection based upon a selector 999. Furthermore, based on a selection of a user, a program schedule of the programs tab 380 automatically populates temperature and humidity settings for each 10 program scheduled event, to achieve a desired selection. This can occur in the programmed setpoints for both temperature and humidity, and further embodiments can include the activation or deactivation of pieces of various environmental equipment, such as heaters, 15 coolers, fan blowers, humidifiers, dehumidifiers, etc.

Turning now to FIG. 9Fi and 9Fii, illustrated are exemplary flows of programming screens that can be used with this embodiment. In flow 1000 of FIG. 9Fi, for a dashboard 350 that is running a program schedule, and 20 flow 1006 of FIG. 9Fii, for an embodiment of the dashboard 350 that is not running a program schedule, instead of a user directly entering the necessary values, the user instead sets the slider 992 of FIG. 9F, and the values are entered into these screens by the slider 992. 25 The flow 1000 has a screen 1001, 1002, 1003, 1004, and 1005. The flow 1006 has a screen 1007, 1008 and 1009.

In one embodiment, if a change of operating parameters is made in the programs screen of the programs tab 380 while a current program is running which employs 30 previously entered parameters, a hold time can be programmed within the programs tab 380, wherein the hold 2625034-1 - 52 - 2010201356 06 Apr 2010 time is entered as exactly what time the previous parameters are to stop taking effect.

In a further embodiment, the dashboard 350 has to set parameters/settings for all devices in the HVAC 5 system 100. There are a few parameters, such as for a blower, that have large ranges that can be very time consuming to set with up and down arrows. Therefore, a coarse scroll bar and a fine scroll bar can be used to adjust such settings (not illustrated). First, the 10 coarse bar is adjusted to get close to the desired range, and then the fine bar is adjusted to get to the exact and precise settings. This can be done by a dashboard 350 that is or includes a touch-screen.
