Installation
If You Are Replacing an Existing Controller
1. Take a photo of the wiring details, which will be useful to reference when
installing the new controller.
2. Unplug the power cord from the AC power outlet and disconnect wires from
the controller.
Mount New Controller
WARNING
• Install the controller with the power supply cord exit side pointing downwards
and through the leftmost opening at the bottom of the controller to avoid
ingress of water.
• DO NOT apply power until you have completed and checked all wiring
connections.
• DO NOT attempt to link two or more controllers together using a single
transformer.
1. Unless installing with custom wiring, choose a mounting location on a wall
within 1.8 m of an AC power outlet and at least 4.5 m away from major
appliances or air conditioners.
2. Drive a mounting screw into the wall, leaving a 3.2 mm gap between the
screw head and the wall surface (use supplied wall anchors if necessary).
3. Locate the keyhole slot on back of the controller and hang it securely on the
mounting screw.
4. Remove the wire bay cover on the lower part of the controller and drive a
second screw through the open hole and into the wall (use supplied wall
anchors if necessary).
Connect Valve Wiring
NOTICE
• DO NOT route valve wires through the same opening as power wires.
• DO NOT connect more than one valve to the same zone terminal (1–6).
1. With the wire bay cover removed, route all field wires through the rightmost
opening at the bottom of the controller and into the wiring compartment.
2. Connect one wire from each valve to one of the numbered station terminals
(1–6) on the controller.
3. Connect a field common wire to
the common terminal (C) on the
controller.

ACCESSORY
Connect Rain or Rain/Freeze Sensor (optional)
NOTICE
• DO NOT remove the jumper wire unless connecting a rain or rain/freeze sensor.
The controller will not function if the jumper wire is removed, and a rain or rain/
freeze sensor is not connected.
• Rain Bird controllers are only compatible with normally closed rain or rain/
freeze sensors.
• Check local and/or state regulations to determine if a rain or rain/freeze sensor
is required.
1. Remove the yellow jumper wire from
the SENS terminals on the controller.
2. Connect both rain or rain/freeze
sensor wires to the SENS terminals.
3. For detailed installation and
operation of a rain or rain/
freeze sensor, refer to sensor
manufacturer's installation
instructions.
Connect Master Valve (optional)
NOTICE
• DO NOT route the master valve wires through the same opening as the power
wires.
• DO NOT connect more than one valve to the master valve terminal (M).
1. Using a direct burial cable,
connect one of the wires from
the master valve to the master
valve terminal (M).
2. Connect the remaining wire from
the master valve to the common
terminal (C).
Connect Pump Start
Relay (optional)
NOTICE
• DO NOT route the pump start
relay valve wires through the
same opening as the power wires.
• A pump start relay connects to
the controller in the same way
as a master valve, but connects
differently at the water source.
• This controller DOES NOT provide
power for a pump. A relay must
be wired according to pump
manufacturer's installation
instructions.
1. Using a direct burial cable, connect one of the wires from the pump start
relay to the master valve terminal (M).
2. Connect the remaining wire from the pump start relay to the common
terminal (C).
3. To avoid possible pump
damage in the event run
times are assigned to unused
stations, connect a short
jumper wire from all unused
station terminals to the
nearest zone terminal in use.
4. For detailed installation and
operation of pump start relay,
refer to pump manufacturer's
installation instructions.
Connect Power
Indoor controller: With the wire
bay cover removed, connect
the power wires to the 24VAC
terminals prior to plugging the
transformer into a power outlet.
Outdoor controller must be
