Valve Output Wiring
The controller transformer provides 26.5 VAC output for
the station valves. The output leads are color coded and
stamped with the corresponding station designations.
(See Figure 3.)

2.
Connect one Lead from EACH valve to the desired
STATION OUTPUT lead using wire nuts. On “C” units,
connect one Lead from each valve to the desired station
output screw on the terminal strip.
NOTE:
A maximum of four Rain Bird, 2 watt, solenoid
valves may be connected to each station output lead.
This applies when the Master Valve circuit is NOT used.
Refer to Figure 4 for variations of the station load capac-
ities.
3.
Connect the second lead from all valves to the white
COMMON output lead. On “C” units, connect the second
lead from each valve to a “COMMON” wire and connect
that wire to a screw labeled “COM” on the terminal strip.
Record the valve locations or landscape zone identifica-
tion for each station on the label inside the cabinet door.
MOUNTING
1.
Choose a location that provides a minimum clearance of 13" wide x 10" high. Since
the electrical connections are provided at the bottom of the cabinet, clearance should
be allowed for the conduit connections etc. (Refer to Figure 2.)
2.
Remove the 4 panel mounting screws, carefully lift out the panel and disconnect the
wire harness at the connectors.
3.
Position the cabinet on the wall at the mounting location, and with a pencil, mark
the 3 mounting hole locations on the wall. Two vertical holes are provided for mount-
ing to a wall stud.
4.
Install the two top fasteners first. (
Note:
Use #10 screws).
5.
Install the bottom fastener, and tighten all screws. With the cabinet mounted se-
curely to the wall, proceed with the wiring connections.
ELECTRICAL CONNECTIONS
ALL WIRING MUST BE INSTALLED AND CONNECTED IN ACCORDANCE WITH
LOCAL CODES. A basic wiring diagram, with color code identification is provided on
the inside surface of the cabinet for easy reference.
