This sprinkler controller allows a master valve or pump start relay to operate whenever a station is on.
From the pump start relay (or master valve); connect one wire to the “Pump” terminal and the other wire to the “Common” terminal.
Note: If you are activating a pump from this controller, you must purchase a Hydro-Rain Pump Start Relay. The HRC 100 has been designed to work with Pump Start relays requiring an inrush current of 0.6 A.
Note: Any time the controller is watering, whatever is wired to this terminal will run concurrently with any of your valves. This terminal is intended for Master Valves or Pump Relays only.
