9V DC BATTERY REMOTE PROGRAMMING
WITHOUT AC POWER
Installing a 9V DC battery on the back of the controller face
plate will allow the controller faceplate to be removed from
housing and can be programmed without being attached to
the controller or any AC power source. The AC power source
is required before any valve activation will commence. The
9V DC battery is necessary to keep the “Current Date/Time”
active. Without the 9V DC battery, power loss will lose
“Current Date/Time” and “Current Date/Time” will have to be
reset upon power resumption.
SENSOR WIRING
A rain sensor or any type of normally closed micro-
switch sensor may be used in conjunction with this
controller. Sensor activation will interrupt controller
output to valves.
1. Route two wires from the sensor through the
bottom of the controller and connect one each
to the two “SEN” terminals. Remove the jumper
wire between these terminals if one exists.
2. The “Rain Sensor” switch on the front of the
face plate can override the sensor if in the
“OFF” position.
Note: If the “Rain Sensor” switch on the front of the
faceplate is in the “ON” position and no sensor is
