Complete this section only if you have a Master Valve installed. Hydrawise controllers work with a normally closed master valve, typically installed at the supply point of the main line, that opens only when the automatic system is activated. This connection in the controller is labeled P/MV. This terminal will supply 24 VAC, 0.28A max, for a single Master Valve solenoid.
Connect either wire from the Master Valve to the P/MV terminal at the base of the module. Connect the second remaining wire to the “COM” (Common) terminal. After the wiring is complete, you can configure the online setup in your Hydrawise account. Learn More
