Control Wires Installation
Step 1 – Route the valve control wires between the valves and the MC-E controller.
For wire runs up to 1000’ between the controller and the valves, it is recommended to use an 18 AWG
(1.0 mm
2
) multi-wire sprinkler valve connection cable. This cable is insulated for direct burial and is color
coded to simplify installation.
Step 2 – Attach one wire from each valve solenoid to the
white color-coded wire from the cable. (Since
the valve solenoid has no polarity, either wire
can be used for this connection.) Designate this
connection as the Valve Common.
Step 3 – Attach a separate cable wire to each of the
remaining valve solenoid wire. Take note of the
wire color being used for each valve as well
as the watering zone/area it is designated. This
information will be important when connecting
the valve wires to the controller’s station
terminals.
Step 4 – Use wire nut fasteners to secure the valve
solenoid wire connection. Waterproof all
connections with grease caps or similar
insulation method.
Step 5 – Route the other end of the control wires into the
provided conduit hole at the bottom of the cabinet. Leave about 8” of cable remaining in the cabinet. Expose
about 3/8” of bare wire from the station and the valve common wires.
Step 6 – Secure the valve common wire to one of the three terminals labeled “VALVE COMMON” and each valve wire
to its appropriate station terminal designation.
