underground installation and is available in various lengths and conductor count.
Select a cable that has at least one conductor for each valve connection and
one conductor to provide a valve common connection.
1. Route the valve control wires between the valves and the controller.
2. Attach the white wire to either lead from each valve solenoid to provide a
valve common wire.
3. Attach a separate wire to the remaining valve solenoid lead of each valve.
NOTE: For reference when making wire connections at the controller, note of
the wire color used for each control valve connection and the corresponding
watering zones.
4. Secure all wire splices using water-proof wire connectors or any appropriate
method of protecting wire splices from direct contact with soil or moisture.
5. Route the cable into the controller through one of the 3/4" (19mm) access
holes in the base of the housing or through the PVC conduit (if installed).
Strip insulation back 3/8" (10mm) for wiring terminal connections.
6. Secure the field common wire(s) to common terminal(s) (C).
7. Secure the individual valve wires to the appropriate expansion module
station output terminals
