VN Unit Controls
Application
The standard remote controller can be used to control individual units or groups of
units up to a maximum of eight. Two remote controllers may be connected on any
group or single application, with one remote being designated as a master.
The device is fitted with an internal room temperature sensor, which may be
configured manually through the engineers menu. Once configured the indoor unit
will sense the room temperature from the remote rather than the indoor unit return
air sensor
Diagram
Connections
The remote controller connects to the indoor unit via a 0.75mm2 two-core cable.
Limitations
The remote controller can control an individual or a group of eight indoor units.
This is reduced to a maximum of seven indoor units where a second remote
controller is to be used.
Application
The simplified remote is used to control an individual indoor unit or a group of up to
eight units. Two devices may be used to control individual or grouped units, where
one device is configured to be a master. The devices are also equipped with
internal room temperature sensors, which may be configured to take priority over
the indoor unit return air sensor. This controller would commonly be used where
simplified operation is beneficial, such as hotel room applications.
Diagram
Connections
The remote controller connects to the indoor unit via a 0.75mm2 two-core cable.
Limitations
The remote controller can control an individual or a group of eight indoor units.
This is reduced to a maximum of seven indoor units where a second remote
controller is to be used.
Application
The infrared remote can be used to control a group of up to eight indoor units and
is equipped with an internal room temperature sensor, which may be configured to
take priority over the indoor unit return air sensor. Should the device be taken
outside its operational range, the indoor unit will automatically revert to sampling
from the indoor unit return air sensor. The device can be used to interrogate the
indoor unit to receive system fault codes, however the engineers menu and data
retrieval function of the standard wired remote controller are not available. Where
indoor units require additional configuration it will be necessary to temporarily
connect a standard wired remote controller, whilst the modifications are made.
Connections
The infrared remote receivers are connected to the indoor units by the AB network
the infrared remote kits used for the different models are listed below. The wall
units have the infrared kit included except the MMK-AP0151H, MMK-APO181H
and MMK-APO241H these models need to be hard wired or use the infrared kit

controller is to be used.
Application
The timer connects directly to a standard or central controller via the 4-core lead,
supplied with the installation kit. No auxiliary power supply is required as the
device obtains a supply via the remote or central controller. Any system being
controlled from the remote or central controller will be enabled or disabled
according to the programmed settings. It should be noted that individual units
cannot be omitted from the program sequence.
Diagram
Limitations
It is important to note that when an RBC-EX21E timer is used other timer
interfaces must not be used. This is essential to avoid conflicting operational
commands.
Application
The interface lead is used to allow single or groups of units connected to the above
devices to be enabled or disabled by means of an external contact.

Connections
The device is connected to the indoor unit via the CN06 socket on the indoor PCB
and the indoor units supply terminals as illustrated.
Limitations
It is important to note that when an RBC-IT3-PE interface is used the standard
24hour timer functions within the Toshiba remote must not be selected to avoid
conflict in switching commands.
The remote controller on/off button will be overridden whenever an interface is
connected to socket CN06, regardless of whether the RBC-IT3PE is in use or not.
All other functions of the remote controller remain unaffected.
It is recommended that the power supply (230v.a.c.) be taken from the respective
indoor unit, as indicated on the wiring diagram.
The field sourced time-switch may be located in any area. The a/c system will start
when terminal 1 of the interface is energised and will override the remote controller
on/off functions.
Due to the logic used, it is recommended that a minimum switching interval of 30
seconds be adopted. When first energised, it may be noticed that the indoor unit
starts briefly and then stops, this is normal and does not indicate a fault with the
system.

The device is connected to the indoor unit PCB via the CN06 socket on the
560/800 KRT models and the CN61 socket on all other models. An adaptor lead is
supplied with the installation kit to facilitate both options.
Limitations
It is important to note that when an RBC-IT4-PE interface is used the standard
24hour timer functions within the Toshiba remote or central controllers must not
be selected to avoid conflict in switching commands. Do not use the standard
RBC-WT1-PE or a RBC-EX21E seven day timer.
The remote controller on/off button will be overridden whenever an interface is
connected to socket CN06 or CN61, regardless of whether the RBC-IT4PE is in
use or not. All other functions of the remote controller remain unaffected.
14
Application
The module is intended to facilitate the installation and control of an external
ventilation fan, which may be used to supply fresh air or to move conditioned air to
another location. The external fan is enabled with the indoor unit, however this can
be over-ridden using the external fan control button on the RBC-AMT21/31E
remote controllers.

Application
The FDP2-F was principally designed to allow a fault condition to be transmitted to
external systems via a relay contact. The FDP2 has several modes of operation
these are configured by using the dipswitches SW1-7 they are as follows.
Fault monitoring
Fault monitoring + locked Cooling preset
Fault monitoring + locked Heating preset
Fault monitoring + locked Auto preset
The FDP2-F has the ability to control two units in a duty share configuration the
units will automatically change over on a 24hour basis and in the event of any fault
both units will be enabled an FDP2-F is required for each indoor unit.
FDP2-F can be networked to give advanced functionality the FDP2-F can be used
as a group controller to control large groups of multiples of eight indoor units. The
controller can linked to other Realtime controls products to give stand-alone BMS
applications for retail or residential applications. Further details of advanced control
options are available on request.

31
Application
The controller is normally used on an installation where there are multiple indoor units in
one location. It gives the ability to link multiple refrigerant systems together for time clock
control and to give an indication of any faults within the systems. There are auxiliary inputs
for on/off control and relay outputs for remote run and fault indication. It is possible to
connect up to ten central controllers on one network, which controls up to 64 master
indoor units from multiple locations.
Connections
The controller requires a 240 Volt single phase 3 Amp power supply, which
connects directly to the mains input terminals on the rear of the device.
32
The two-core network cable should be screened and have a minimum cross-sectional area
of 1.5mm for networks of up to 1000 meters. This should be increased to 2.5mm for
networks of 1000 to 2000 meters total length. The network cable terminates at the U1/U3
and U2/U4 connections on the rear of the device.
Terminals A1, A2 and A3 are used to remotely operate all of the connected indoor units.
The indoor units can be enabled with a pulse voltage of 24 Volts applied for 0.5 seconds
between terminals A1-A3 and disabled by applying the same voltage between terminals
A2-A3.
Terminals B1, B2 and B3 provide dry contact outputs for connection to other systems. A
relay contact will close between B3 and B1 indicating system operation and B3 and B2
indicating a fault on any connected units.
Terminal CN02 can be used to connect a 7day timer (RBC-EXW21E) or alternatively the
RBC-SMTI interface lead can be connected and used as a means of remote switching.

34
Application
The device is ideally suited to locations where it may be necessary to remotely enable or
disable indoor units. An example of this would be a hotel reception desk, where the
receptionist may wish to enable a customers room air conditioning during the check-in
process or disable it on the departure of a customer. Each of the on/off buttons has a label
facility and again using the example of a hotel installation, the buttons could be labeled
with a room number. For larger installations up to 4 controllers could be installed on one
network, thus allowing 64 master indoor units to be controlled from one location.
The device also has the facility for interfacing time clock control, remote switching, remote
run signal and remote fault indication from a set of auxiliary contacts.

Application
The device consists of a small PCB, which should be installed within the indoor
unit and would typically be used where the indoor unit/units will be interfaced with a
Central Controller or any other network device, such as a BMS system. One device
is required for each indoor unit or group of indoor units. Where indoor units are
grouped together they will be assigned with one address on the central device and
will consequently all receive the same operational instructions.
Diagram
40
Connections
The device connects to the indoor unit PCB via socket CN50 and will provide two
terminal network connection designated U3 & U4.
Where multiple devices are to be installed it is necessary to set one unit with a
100ohm termination resistance. This would normally be on the device connected to
the unit with the lowest network address. The resistance being set by SW01 bit
being set to ON.
When the device/devices have been installed and a termination resistance applied
it is then necessary to apply a unique network and refrigerant line address to each
unit.
Addressing Procedure
The address setting is carried from a standard RBC-AMT21/31E remote controller.
Where units do not have standard remote controllers installed, one should be
temporarily attached in order to carry out the configuration process.
Accessing the Engineers configuration menu
Press Set CL & Check Simultaneously for 4 seconds.
Navigate to menu item 12 (refrigerant line address) using the Temperature Set
Buttons.
Set a unique line address using the Timer Set Buttons and then press SET.
Navigate to menu item 03 (network address) using the Temperature Set Buttons.
Set a unique network address using the Temperature Set Buttons and then press
SET
Press the CHECK button to complete the setting process
Generally speaking the refrigerant line address would mirror the network address,
however this would not be the case with grouped units, which would have the
same network address but different line addresses.
Limitations
It is recommended that 1.5mm2 2-core screened cable be used on all networks up
to a maximum of 500Mtrs in length.
The KRT range of units do not require adaptors as they are supplied with U3 & U4
connections and also have a termination resistance facility on the indoor PCB. The
termination resistance being set by SW01 bit 1 being set to ON.
41
Application
The software is used when a computer solution is required in order to provide a flexible
solution to allow the air conditioning to be fully controlled from one central point. It offers
much functionality, which is suited to small and large systems.
Frost Protection
The software has the ability to sample the air temperature from an individual or a selection
of indoor units. Then, based on this data, operate the air conditioning to give frost and
fabric protection to the building
Energy monitoring
The energy monitoring software can be included to calculate the running costs of the
individual indoor units. This data can then be provided in structured bills for the building
tenants. This data is calculated from the demand given from the indoor units and the
power consumed by the system. The RBC-EM1-PE power meter is required for this
function. This option is covered in a separate data sheet.

Connection/Installation Procedure
The BACnet solution consists of several different components, which have been
listed below. The maximum number of indoor units that may be controlled is 128
per Intelligent Server. Up to a maximum of eight Relay Interfaces can be
connected per Intelligent Server.
Intelligent Server BMS-LSV4E
The intelligent server connects to the BACnet system by a network connection,
usually to a local hub. The Relay Interfaces connect to the server by the RS485
network and up to eight Relay Interfaces may be connected, with a maximum of
128 indoor units. The Intelligent Server requires a 240V 3A mains supply.
BACnet Software BMS-STBN05E
The BACnet software is contained on a standard Compact Flash Card, which plugs
directly into the Intelligent Server.
TCS Net Relay Interface BMS-IFLSV2E2
The Relay Interface connects to the Touch Screen Controller via the RS485
Network, (A & B connections). The air conditioner network connects to the U1 &
U2 connections, with a maximum of 64 indoor units served. The Relay Interface
requires a 240V 3 A mains supply.
Software
Site-specific software is written for the BACnet solution and then uploaded to the
Intelligent Server. This gives site-specific names and locations, which are then
presented to the BACnet network.
Limitations
The total length of the air conditioner U1/U2 network for each relay interface is as
follows.
1.5mm2 Screened up to 1000m
2.5mm2 Screened up to 2000m
The total length of the RS485 Network A/B
1.5mm2 Screened up to 500m
The total length of the Ethernet cable from the Hub to the server should be a
maximum of 100M
The IP Address range should not be used xx.xx.0.xx
55
Application
The LTX-21 solution is designed to allow connection to a Trend BMS system. It
allows a fully functional solution to be achieved. The LTX-21 and associated
Toshiba LonWorks gateway are usually mounted in the control panel with the
outstation. We have two possible variations, which are outlined below.
LTX-21 and RBC-LG1 Combination
This uses a LTX-21 and an RBC-LG1-PE, which connects to a maximum of
sixteen indoor units however; the TCB-PCNT20TLE network adapters are required
to convert back to the AI network. This option will be cost effective for single split
installations with less than 7 indoor units for all other situations use the solution
below.
LTX-21, LTX-VCI and TCB-IFLN640TLE Combination
This solution uses an LTX-VCI and TCB-IFLN640TLE for the control of a maximum of 64
indoor units. The solution uses an LTX-21 for every 16 indoor units as these connect to
the Trend outstations. For example, for a total of 64 indoor units you would use four LTX21s.
In each of the above cases, multiples of the above combinations can be used to
accommodate larger systems.
56
Connections
LTX-21 and RBC-LG1-PE Combination
The LTX-21 requires a 24V dc supply and the LonWorks gateway requires a 240v supply.
The devices are linked on a LonWorks network.
The XY network is connected via a screw terminal connector. The recommended cable is
2-Core Screened 1.5mm2.
A serial cable connects the LTX-21 to the outstation.

Application
Option 1
The first option is the simplest form of control it does not allow control with the air
conditioner system. The mechanical switch is straightforward to install as it only
involves the switching of the relays. If required the fan speed or the damper can be
fixed in a particular mode
Option 2
The Second option allows the VN unit to be enabled from an indoor unit this
utilizes the RBC-SMFI Fan interface. This link means the unit needs to be operated
in conjunction with an associated indoor unit.
Option 3
Option 3 is a low voltage option, which gives a dedicated controller for the VN unit
this control option, will allow a Heater to be controlled to protect the fabric of the
unit. This option can also be integrated with the indoor units via the RBC-SMFI fan
interface.
Option 4
The final option indicates the procedure for connecting and control using
interactive intelligence. This allows full control from the PC of the VN unit the units
can independently time controlled to only provide ventilation when the building is
occupied.
64
Controls:
ON/OFF (switch 1)
Fan Speed - High/Low (switch 2)
Mode - Bypass/Heat Exchange (Damper on/off) (switch 3)
For some of the smaller projects, this may be the most convenient and cost
effective solution.
Note that this option is only available if there are no Toshiba heaters provided with
the heat exchangers.

More than one heat exchanger unit can be connected to the same indoor fan coil
unit. In order to do so, the heat exchanger units need to be wired in parallel.
However, the current may be too large and an additional higher amperage relay
(provided by others) may be required. The RBC-SMFI would then turn the relay
ON.
Note that this option is only available if there are no Toshiba heaters provided with
the heat exchangers.
