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 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 con-
troller 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.
