How to wire a sprinkler pump

HowToLou (author)  Christiansen.Dav2 years ago
You need a 24-volt pump relay. Wire the 24-volt side of the relay to the "Pump" and "Common" screw terminals you see in the video. Wire the 120-volt side of the relay, like a switch, to the power line going to the pump. Whenever the system turns on any zone, it also turns on the pump relay switch to the pump.
