RC2/ARC Series WiFi Smart Controller: Watering Issues

Issue: The water source is not supplying water.
Solution: Verify that the main water line is not disrupted and that all other water supply lines are open and functioning properly.

Issue: Wiring is loose, not properly connected, or damaged.
Solution: Check that the wiring is securely connected to the controller and in the field. Check for damage and replace it if necessary. Check wiring connections and replace them with watertight splice connectors if required.

Issue: The connected rain sensor may be activated.
Solution: The Rain Bird App will indicate if a rain sensor is activated. Let the rain sensor dry out, or disconnect it from the controller terminal block and replace it with a jumper wire connecting the two SENS terminals.

Issue: The jumper wire connecting the two SENS terminals on the terminal block may be missing or damaged.
Solution: The controller will not function if the jumper wire is removed and a rain or rain/freeze sensor is not connected. Jumper the two SENS terminals on the controller terminal block by connecting them with a short 14- to 18-gauge wire length. If a rain sensor is installed, ensure both rain sensor wires are properly seated in the SENS terminals.

Issue: Excessive watering
Programs may have multiple watering run days and start times that were set unintentionally.
Solution: Watering run days and start times apply to the entire program, not individual zones. Programs (A, B, or C) only require a single start time to run.

Issue: Watering even after turning the controller off
Issue with one or all the valves or supply lines.
Solution: Clean, repair, or replace the valve. If that does not resolve the issue, contact a licensed contractor.

Issue: Seasonal adjust is not altering the schedule
The controller is not connected to WiFi to make automatic adjustments.
Solution: The mobile device needs to be reconnected to the controller or connected for the first time, and Seasonal Adjust must be toggled to “on” in the program settings. Note that seasonal adjust are set by the program and should be properly adjusted in all active programs.
