1. Route the valve control wires between the valves and
the timer.
Note: Using 18 AWG (0.75 mm
2
) multi-wire sprinkler
valve connection cable is recommended. This cable
is insulated for direct burial and is color-coded to sim-
plify installation.
2. Attach the white color-coded wire from the cable to
one
wire from each valve solenoid. (Either solenoid
wire can be used for this connection.) This is called
the
valve common wire.
3. Attach a separate cable wire to the remaining wire
from each valve solenoid. Make a note of the wire
color code used for each valve and the watering zone
it controls. You will need to have this information
when connecting the valve wires to the timer.
4. Use screw-on wire fasteners to secure each wire con-
nection. Waterproof all connections with grease caps
or simular insulation method.
5. Route the wire cable into the timer. Strip insulation
back 1/2" (13mm) from all cable wires.
Note: The ECx has snap-in wire terminals. To attach
wires, simply raise the lever, insert the stripped wire,
and press the lever down to secure.
6. Referring to the Timer Components on page 5 and the
diagram above, secure the valve common wire to the
terminal labeled COM (11). Connect the individual
zone valve wires to the appropriate zone module ter-
minals (14). Connect the master valve wire (if applica-
ble) to the terminal labeled PUMP/MV (10).
Note: Connecting a master valve (or pump relay) is
optional and may not be required in your sprinkler
system.
