CONNECTING A MASTER VALVE

NOTE: Complete this section only if you have a

master valve installed in your irrigation system. A

master valve is a “normally closed” valve installed at the

supply point of the main line that opens only when the

controller initiates a watering program.

At the Master Valve, attach the common wire to either solenoid

wire of the valve. Attach a separate control wire to the remaining

solenoid wire.

2. The common wire should be attached to the C terminal inside the

controller. The other wire coming from the master valve should

be attached to the P terminal inside the controller. Tighten each

terminal screw.
