(The RC-4C and RC-1260C Controllers have similar controls and features.)
DESCRIPTION OF CONTROLS Refer to Figure 1
A. HOUR DIAL with 23 CYCLE START PINS: The HOUR dial contains 23 pins for
scheduling automatic "Starts" on any hour (except midnight - which is day changeover
time). Embossed characters provide quick identification for each hour, AM or PM,
noon and midnight. Captive type pins are designed for simple push-pull operation.
B. DAY DIAL with 14 SCHEDULING PINS: The calendar DAY dial contains 14 captive pins for scheduling irrigation everyday or any day within a two week range. Each
pin represents a 24 hour period beginning at midnight. Embossed characters are on
the dial, adjacent to each day of the week.
C. STATION SELECTOR/INDICATOR DIAL: The STATION selector/indicator dial
contains the timing controls for each of the stations. The dial automatically rotates during a watering cycle with the current station appearing at the top under the station
pointer. REST indicates the system is off and no watering is taking place. The dial is
also used for manual selection of any station for semi-automatic operation.

D. STATION TIME CONTROL KNOBS: Individual TIME controls for each station.
Timing is adjustable from 3 to 60 minutes (6 to 60 minutes in the RC 1260C) to suit all
landscape growth requirements. A small white arrow moves with each knob along the
timing scale on the Station dial (C) for visual indication of the time setting. The scale is
marked-off in 5 minute graduations and the ratchet action of the knob provides for precision adjustment with each "notch" representing one minute increments. The OFF position eliminates the station from the watering schedule. All omitted stations are automatically “rapid advanced” through, to the next timed station.
E. OPERATIONAL MODE SWITCH: The 2-position MODE switch (E) provides the
operating control for the system. AUTO position for automatic irrigation as scheduled
and "timed" watering of manually selected station. The OFF position is used for rainy
weather shutdown. This position eliminates controller "output" to the system valves
without interrupting the clock operation.
F. CIRCUIT BREAKER RESET BUTTON: Circuit overload reset button (F). A built-in
circuit breaker protects the controller from damage due to current overload. Push to
reset after the source of trouble has been remedied.
G. CURRENT STATION INDICATOR: STATION indicator (G) identifies the current
position of controller operation.
H. CURRENT TIME INDICATOR: TIME indicator (H) identifies the current time on the
controller clock.
I. CURRENT DAY INDICATOR: DAY indicator (I) identifies the current day of the watering schedule.
INSTALLATION
The RC Series controller’s cabinet is suitable for wall mounting in sheltered areas.
Three mounting holes are provided through the back surface of the cabinet. Before
mounting the controller, consideration must be given as to accessibility, electrical
power source and connections to the system control valves.

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 mounting 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.
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.)
1. A 1/8" dia. hole is provided in the bottom of the cabinet
for connection of a 3/4" conduit fitting.
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 capacities.
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 identification for each station on the label inside the cabinet door.
