The RC-4C and RC-1260C Controllers have similar controls and
features.
RC-C Dial Features.
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 126OC) 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-C 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.
CAUTION with RC-C Series:
"Dead-Heading" a pump (running the pump's motor without water flowing through it) may cause pump damage. It may also result in personal injury from hot water spraying from the pump as a result of static water within the pump heating to a temperature where plastic pipe and fittings may melt and discharge the water. ALL CONTROLLERS USING PUMP START RELAYS ON MASTER VALVE/PUMP START CIRCUITS MAY ENCOUNTER THIS PROBLEM. As a safeguard against such an incident the following procedure is highly recommended.
All UNUSED stations on an electro mechanical controller must be connected to a station on the controller where a valve is present if a pump start relay is used to start a pump. This installation method eliminates possible pump dead-heading if station timing is inadvertently programmed on a station where a valve is not present. See details on Page 5 of your manual
