Controller Wiring Guide
In the diagram below, you see a clear example of the wiring for a four valve controller system.
1 - The "P" wire
- The wire connecting to the master valve
2 - The Master Valve
- The master valve is an isolating valve that is an additional feature on certain controllers. A master valve will isolate your irrigation system and minimize water leaks.
3 - The Common Wire
- The common wire needs to connect to every valve that will be communicating with the controller.
4 - The Station Wires
- Depending on the size of the controller, you will have number station zones. In this example of 8 zone controller and stations, 1 to 4 are currently in use in the diagram. Each valve needs its individual station wire, 1 zone cannot control two valves.
