Hunter Pro-C "P Err" and Zone Errors – Pump Start Relay Wiring

Hunter Pro-C with submersible pump shows "P Err" or zone errors. Pump runs when relay powered externally.

Diagnosis

  1. Disconnect pump start wire at controller.
  2. Run each zone manually. If error clears → short in pump start wire or relay.
  3. If error remains with wire off → controller or zone wiring/solenoid.
  4. Test each zone individually to isolate.

Trial and error with volt/ohm meter needed.
