The "MV ERR" reading on the Rain Bird ESP-4 indicates a fault in the master valve (MV) or pump circuit. This error is usually caused by a short circuit in the wiring.
To resolve it: 1. Identify and repair the fault in the MV or pump wiring. 2. Set the dial to AUTO. 3. Press the ADVANCE button to clear the Alarm LED.
