Connect Field Wiring
Field wires are connected to module terminals using quick
connectors. Press the spring arm of the appropriate terminal and
insert the wire. When you release the spring arm, the clamp will
hold the wire.
Connect one of the valve wires to one of the numbered
terminals, as shown in the illustration.
Connect the other valve wire to a common wire. All common
wires should be connected to any one of the COM terminals on
the controller. Wires used to connect the valves must be code-
approved for underground installation.
NOTE:
Complete the following step only if your
system uses a master valve or a pump start relay. The
controller does not provide main power for a pump.
Connect the master valve or pump start relay wiring to the MV
and COM terminals, as shown in the illustration.
