the timer.
Note: The snap-in wire connectors accept 14–18
gauge (2mm2–1mm2) wire. Using direct-burial irrigation
cable is recommended. Choose a cable that has at
least one additional wire conductor than the number of
valves to
be connected.
2. Attach the white color-coded wire to
either one of
the wires from each valve solenoid. This is called the
valve common wire.
3.
Attach an individual color-coded wire to the remaining
wire from each valve solenoid. Make a note of the wire
color used for each valve and the watering zone it controls. You will need this information when connecting
the valve wires to the timer.
CAUTION: Use Toro Waterproof Wire Connectors
(Model # 53687) or grease caps on all exposed wire
splice connections to prevent corrosion, connection
failure and possible short circuit.
4. Route the wire cable into the timer through the large
opening in the base of the housing, or through PVC
conduit (if installed). Strip insulation back 3/8″ (9mm)
from all wires being used.
