CONNECTING A MASTER VALVE
NOTE: Complete this section only if you have a
master valve installed in your irrigation system. A mas-
ter 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 termi-
nal screw.
