Master Valve and Station Connection
Using 18-gauge (maximum 14-gauge wire can be used), multi-strand, direct burial
irrigation valve connection cable is recommended. Select a cable that provides at least one
wire for each valve and one extra wire for the common connection.
IMPORTANT! To prevent corrosion and possible short circuit, use waterproof wire
connectors on all splices.
Step 1 – To provide a valve common connection, splice one cable wire (generally the white
wire) and connect it to one solenoid lead from each of the valves.
Step 2 – Connect a separate wire to the remaining solenoid lead from each valve.
For reference, note the wire color code being used for each valve connection
and the associated watering station.
Step 3 – Remove the controller’s lower
panel cover to access the master valve
and station terminals.
Step 4 – Route the wire cable into the controller
through the opening at the base of the
unit.
Step 5 – Secure the designated valve common
wire to the “COM” terminal.
Step 6 – Secure the Master Valve to the “MV”
terminal and the stations to their
corresponding terminals (S1, S2, S3, ...).
Step 7 – Reinstall the lower panel cover.
