Connecting the Valves

Note: Using 14 to 18 AWG (2.5mm
cable is recommended. This cable is made specifically for
automatic irrigation systems and is available in several
lengths and conductor count. Always use a cable that has
at least one wire for each valve and one wire for the valve
common connection.
1. Route the wire cable from the valve location into the
controller cabinet.
2. Attach the white (preferably) cable wire to either wire
from each valve solenoid. This is called the valve
common wire.
Note: The solenoid does not have specific polarity,
so either wire can be used for the common wire
connection.
3. Connect an individual color-coded cable wire to the
remaining solenoid wire of each valve. Make a note
the wire insulation color used for each connection and
the sprinkler zone controlled by the valve.
IMPORTANT: To prevent possible short-circuit
conditions causing controller damage, properly
connect, insulate and waterproof all wire splices.
4. Remove 1/2" (13mm) of insulation from the end of all
cable wires to be connected to the controller.

Note: The station module has snap-in wire connectors.
To attach wires, simply raise the lever and insert the bare
wire end into the small hole beneath the lever. Press the
lever down to secure the wire. Pull lightly on the wire to
confirm that it is locked into the module.
5. Referring to the Controller Components on page 5 and
the diagram above, secure the valve common wire to
the terminal labeled COM (8). Connect the individual
valve wires to the appropriate expansion module ter-
minals (11). The stations are numbered from left to
right, 1 through 12. Connect the master valve wire
(if applicable) to the terminal labeled PUMP/MV (9).
