Possible Cause
Water source not supplying water.
Wires not properly connected.
Wires loose or cut; corroded connections.
Dial not set to AUTO position.
If you have a Rain Sensor, it may be activated.
If you do not have a Rain Sensor, the wire
connecting the two yellow Rain Sensor
terminals may be damaged or missing.
An electrical surge may have damaged the
Controller's electronics.
Possible Cause
Transformer not plugged in or wall socket
not supplying power (Red light on the
transformer is not illuminated).
An electrical surge may have damaged the
Controller's electronics.
Possible Solution
Make sure the main water line and all supply lines are open and operating properly.
Make sure all field wires and master valve/pump start relay wiring is connected properly.
Check field wiring for broken, cut, or "skinned" wires and replace if necessary. Check all wire connections
and replace with watertight splice connectors as needed.
Make sure the dial is on AUTO position—not any other dial position.
You can either wait until the Rain Sensor dries out, or disconnect the Rain Sensor from the yellow
terminals on the Controller and replace it with a wire connecting the two yellow terminals.
Connect the two yellow Rain Sensor terminals in the Controller's terminal bay with a short length of 14
to 18 gauge wire.
Press the reset button under the wiring cover. If there is no permanent damage, the Controller should
resume normal operation. You will need to input the current time and date, but your watering schedule
should remain intact.
Possible Solution
Make sure the two-prong connector is connected and the transformer is securely plugged in.
Make sure the main AC power supply is working properly.
Unplug the Controller for 3 minutes. Plug the Controller back in. If there is no permanent damage, the
Controller will accept programming and resume normal operation.
