CONNECTING THE VALVE WIRING

1. To provide a fi eld common wire, attach one wire to either solenoid lead of all sprinkler
valves and master valve (optional). See
2. Attach a separate control wire to the remaining solenoid lead of each valve. Label the
control wires with the intended station number for identifi cation at the controller.
Caution:
All wiring splices must be waterproofed to prevent short circuits and
corrosion.
Pump Start Relay
or Master Valve
Caution:
A maximum load of 24 V a.c. (0.5 amps) may be connected to each
station. A maximum load (including master pump relay or master valve) of 50 VA
(2 amps) may be programmed to operate simultaneously. Exceeding these limits can
damage the controller.
3. Route the control and common wires into the controller cabinet. Remove approximately
1/2" (13 mm) insulation from the ends of each wire. Shorter lengths of the exposed wire
will be inadequate for contact.
NOTE:
The quick-connect terminal blocks will accept one 12 AWG (4 mm2) or two 14
(2.5 mm2) AWG solid copper wires in each position. Insert the wire into either opening
provided. Pull lightly after insertion to ensure positive retention. To release the wire,
press either tab located directly above and below the terminal.
4. Two fi eld common terminals are provided for each 12-station terminal block. Attach the
fi eld common wire(s) to the terminal(s) labeled vc/com.
5. Referring to Figure 4, connect each valve control wire to the appropriate station number
terminal.
NOTE:
The Hot Post (see item 25 on page 3) provides 24 V a.c. to enable valve
identifi cation at the controller. With the valve common connected, simply touch the station
wire to the Hot Post to energize valve.
