Pro-C - Connecting a Pump Start Relay

Installation Details
  1. Route a wire pair from the pump relay into the controller housing.
  2. Connect the pump common wire to the terminal slot “COM” (Common) and the remaining wire from the pump relay to the P/MV terminal slot.

Relay holding current draw must not exceed 0.28 amps (24 VAC). Do not connect the controller directly to the pump — damage to controller will result.

Note: On the older style Pro-C controller (green buttons) the common terminal and the PM/V terminal are located on the main module.
