Questions and answers
The display reads PR OFF. I can’t get the system to operate. Do I need a new control box?
"PR OFF" on the Rain Bird ESP-4TM display means the controller is in "Program Off" mode, which prevents automatic watering.
To fix this:
1. Turn the dial to "AUTO" to enable automatic operation.
2. Ensure the controller has 24V AC power using a multimeter. The battery does not power the controller; it only maintains settings.
3. If power is present and it still shows "PR OFF", there may be a faulty AC connection or internal issue.
Try resetting the controller by disconnecting all power (AC and battery), then reconnecting. If the issue continues, internal repair or replacement may be needed.
