(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 securely 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.
