Step 1
– Route valve wires from the valves, master valves, pump relay and/or sensor into the controller cabinet.

and is color-coded to simplify installation. It can be routed directly into the controller through the access hole provided for
valve wire conduit (if conduit is not used).
Step 2
–
to one wire from each valve solenoid and/or pump relay. (Either of the two wires from the solenoid or pump relay can be used
for this connection.) This connection will be designated as the valve common wire.
Connect a separate cable wire to the remaining wire from each valve solenoid. Note the wire color-code used for each valve and
the zone it controls. You will need this information when connecting the valve wires to the controller.

Step 3
– Secure all wire splices using wire nut connectors. To prevent corrosion and possible short circuits, always use an insulated wire
nut, grease cap or similar waterproofing method.
Step 4
–
Secure the individual valve wires to the appropriate zones they control, Zone 1 valve to terminal 1, Zone 2 valve to terminal 2, etc.
