Overview of the MAXICOM Central Control System
The ESP-SAT controllers are one part of Rain Bird’s MAXICOM Central Control System.
(See the illustration on the next page.) The satellite controllers receive commands from the
cluster control unit (CCU) and operate stations according to schedules programmed at the
central computer.
The MAXICOM Central Control System chiefly consists of seven parts:
1. Central Computer uses MAXICOM software program to control the entire irrigation
system.
2. Computer Data Path transfers information from the central computer to the CCU by
phone communication or by radio/direct communication.
3. Cluster Control Unit operates field devices by executing commands received from the
central computer.
4. Satellite Data Path transfers information from the cluster control unit to the field
devices by a two-wire path (TW) or by MAXILink radio
communication.
5. Field Devices include either satellite controllers or decoders:
Satellite controllers — send a 24 VAC power signal to each

station.
Decoders — control and monitor system functions.
6. Stations consist of irrigation valves, sensors, or switch-operated devices.
7. Weather Station interprets weather conditions and sends information to the cen-
tral computer.
Note: Your ESP-SAT controller is already set up for satellite data path installations. Some additional
equipment may be required for some types of installations.

tions for all five types of connections.
To connect the valve wires,
Important: All wiring must be installed and
connected in accordance with local codes. 1. Route each valve wire up through the
large hole at the bottom of the controller
cabinet.
For Pedestal-mount models, route the

valve wires through any of the three
holes.
2. Strip 1/2" (1.3 cm) from the end of the

valve wire. Insert the wire into the
appropriate station terminal. If the wire
does not enter securely into the hole,
press down on the orange lever as you
insert the wire.
17
Note: Each station has two holes because each

station is capable of operating two valves.
3. Repeat for all used stations.
4. Attach the valve common wire to one of

the two common terminals in the same
way.
5. If your system includes a master valve

or pump start, connect the wire from
that device to the MV (master valve)
terminal on the controller in the same
way you connected the other wires.
Note: MV2 (master valve 2) is enabled when
any station operates. MV1 (master valve 1) can
be be enabled or disabled for each individual
station. See page 42 for more information.

Chapter 3: Programming and Operation
The ESP-SAT controller will usually operate automatically, receiving commands from the
central computer. A satellite controller can also operate as a stand-alone controller, using
locally programmed instructions. Local programming will be used, for example, if the satel-
lite loses communication with the CCU. You can use the keypad to program the controller
locally so that it will operate automatically. You can also make changes in watering sched-
ules without disturbing the programmed information.
This chapter will guide you through the use of the controller's keypad and LCD, as well as
the local programming and operation of the controller.

Programming
This section of the manual contains instructions for programming your ESP-SAT controller
locally. The controller comes from the factory without a pre-set default program.
Before you begin programming, it is a good idea to chart your watering schedule on a piece
of paper, taking into account the schedule for all stations and how often you want to repeat
the schedule. A blank schedule is provided for you on pages 54-55.

The following pages contain possible problems you may encounter and some solutions.
Before calling Rain Bird, check this list. If you cannot solve the problem yourself, call our
Technical Service Hotline at 1-800-247-3782 and we will be glad to help you.
Problem: The power to the controller is interrupted for an extended period of time.
Solution: The controller has a 9-volt battery to keep data and instructions for up to 24
hours. When there is a power outage, the time of day will be displayed, but no
watering will take place. When power is restored, watering will resume.
Problem: The display will not light.
Solution: Check the main power source and the plug. Check to see if there is a blown fuse
inside the controller.
Problem: The display is flashing.
Solution: There may be a power outage. Or check the battery; it may be dead or not con-
nected properly.
Problem: No watering is taking place.
Solution: Check the circuit breaker; it may have tripped. Also check the cables inside the
controller; they may be improperly connected.

Appendix B: Installing a MAXICOM Interface Board
Before You Begin
Important: Before installing the MIB, make sure that the area around you is free from dirt and
dust and that your hands and arms are clean. This will avoid contamination of the ESP-MC
controller’s internal parts.
Warning! Don’t let water or other liquids come in contact with any part inside the con-
troller cabinet.
Overview of the MAXICOM Interface Board (MIB)

To convert your ESP-MC stand alone controller into an ESP-SAT satellite controller, you
must install the MAXICOM Interface Board (MIB). Once installed, the MIB allows your
ESP-MC controller to function as either an ESP-SAT controller in conjunction with the
MAXICOM irrigation system, or as a stand-alone unit.
Before you install the MIB, you must determine how your controller will communicate with
the cluster control unit (CCU): two-wire path or wireless radio path. If your controller will
communicate with the CCU via two-wire path, follow the instructions on page 57,
Installing the MIB (TW). If you controller will communicate with the CCU via wireless
radio path, follow the instructions, "Installing the MIB (LINK)," on page 61.
The two installation types require different MIB kits. The MIB kit for the two-wire
connection is ESP-MIB-TW; the MIB kit for the wireless radio is ESP-MIB-LINK. Be certain
that you have received the correct MIB kit before you begin the installation.
