Rain Bird ESP-TM Troubleshooting: Manual Start Failure

Controller Reset Procedure

When manual start fails despite good battery and fuse, the controller likely needs a hard reset.

Step-by-Step Reset

Remove 9V backup battery.
Power off controller (unplug or breaker) for 1 minute.
With battery still out, restore power.
Test manual operation.

Diagnostic Next Steps

If display shows valve should run but doesn't: use voltmeter on controller terminals. Test between station terminal and common (C). Should read 22-26 VAC. If voltage present, problem is field wiring, valve solenoid, or water supply. If no voltage, controller board is faulty.

Resolution Path

Voltage at controller → check valve wiring/solenoid.
No voltage → replace controller panel or entire unit.
