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.
1. 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.
