Connecting a Pump Start Relay

NOTE: Complete this section only if you have a pump start relay installed. A pump start relay is a device that uses a signal from the controller to actuate a separate electrical circuit to energize a pump to provide water to your system.

The controller should be mounted at least 4.5 m away from both the pump start relay and the pump. When a pump start relay comes on it sends out surges that may potentially cause damage to a controller that is mounted too close. When a pump is to be operated by the controller, a pump start relay must be used. Hunter offers a full range of pump start relays for most applications.

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

Relay holding current draw must not exceed .28 Amps. Do not connect controller directly to pump – damage to controller can result.
