How to Wire a Pump Relay to an Orbit Timer

Many systems will have a master valve or a pump that needs to be turned on to allow the water to get to your valves.

You should have two wires coming off of this valve/relay.

One wire will go to the terminal labeled Pump, and the other wire will go into the common terminal (C).


Note: Any time the timer is turned on, whatever is wired to this terminal will run along side any of your valves. This terminal is intended for Master Valves or Pump Relays only.
