How to Connect a Hunter X-Core 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 a 15 ft (4.5 m) away from both the pump start relay and pump to minimize any potential electrical interference.

  1. Route a pair of wires from the pump relay into the controller.
  2. Connect a common wire to the C (Common) terminal inside the controller and connect the remaining wire from the pump start relay to the P(Pump) terminal.

Relay holding current draw must not exceed 0.3 A. Do not connect the controller directly to the pump or damage to the controller will result.
