Issue: The controller will not connect to the mobile device, and the Rain Bird App displays a “Communication Error.”

Issue: The controller will not connect to the mobile device, and the Rain Bird App is displaying a “Communication 503” error.
Solution: Only a single device can connect to the controller at one time. Close out of the Rain Bird App on all mobile devices and wait approximately 30 seconds before accessing the controller from a single device.
Solution: Apple iOS and Android require Location Services to be enabled for the Rain Bird mobile app to function correctly. Verify that Location Services is toggled on for the Rain Bird App in your mobile device settings. Close out of the Rain Bird App and wait approximately 30 seconds before accessing the controller from your mobile device.

Issue: The controller is frozen and is not responding to manual operations at the controller interface:
An electrical surge may have interfered with the controller’s electronics.
Solution: Press and release the RESET button in the controller wiring bay. This will temporarily prevent the controller from getting power from the input. If there is no permanent damage, the controller should accept programming and resume normal operation.
Solution: Unplug the controller for two minutes, then plug it back in. The controller should accept programming and resume normal operation if there is no permanent damage.
