Connecting a Pump Start Relay

NOTE: Complete this section only if you have a pump and pump start relay installed. A pump start relay is an electronic device that uses a signal current from the irrigation controller to activate a pump to provide water to your system.

The controller should be mounted at least 15 feet (4.5m) away from both the pump start relay and the pump. When a pump is to be operated by the controller, a pump start relay must be used. Hunter offers a full range a pump start relays for most applications.

1. Route a wire pair from the pump relay into the controller housing.
2. Connect a common wire to the terminal slot C (Common) and the remaining wire from the pump relay to the P/MV screw slot.

Relay holding current draw must not exceed .28 amps. Do not connect the controller directly to the pump – damage to controller will result.
