RC-7BI MODEL SHOWN
(The RC-4Bi has a 20-minute pause position between station #4 and "REST.")
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.

D
C. STATION SELECTOR/INDICATOR DIAL: The STATION selector/indicator dial
contains the timing controls (D) 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 up to 60 minutes 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 to
the next timed station.
E. OPERATIONAL MODE SWITCH: The 2-position MODE switch provides the operating control for the system, AUTO position for automatic irrigation as scheduled and
"timed" watering of a 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. FUSE: 1.5 AMP (Slow Blow fuse) protects the controller from damage due to current overload. Replace fuse after the source of trouble has been remedied.
G. CURRENT STATION INDICATOR: STATION indicator identifies the current position of controller operation. See control (C).
H. CURRENT TIME INDICATOR: TIME indicator identifies the current time on the
controller clock.
I. CURRENT DAY INDICATOR: DAY indicator identifies the current day of the watering schedule.
INSTALLATION
The controller is housed in a cabinet suitable for convenient indoor wall mounting.
Four mounting holes are provided through the back surface of the cabinet. Before
mounting the controller, consideration must be given as to accessibility, protection
from water, electrical power source and connections to the system control valves.

MOUNTING
1. Choose a location that provides a minimum clearance of 13" wide x 8" 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. The location must be
within 5 feet of an electrical outlet.
2. Remove the 4 panel mounting screws, and carefully lift out the panel.
3. Position the cabinet on the wall at the mounting location, and with a pencil, mark
the mounting holes desired (4 holes are provided) on the wall. Two vertical holes are
provided for mounting to a wall stud. (Note: Use #10 screws).
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.
A 1/4" dia. hole is provided in the bottom of the cabinet for insertion of the transformer
input wire. See Figure 4.
Valve Output Wiring
The controller transformer provides 24 VAC output for
the station valves. The output leads are color coded and
stamped with the corresponding station designations.
(See Figure 3.)
1. Connect one Lead from each valve to the desired station output lead using wire nuts.
NOTE: If the Master Valve/Pump Start circuit is used,
connect only one Rain Bird, 2 watt, solenoid valve per
station.
2. Connect the second lead from all valves to the white
common output lead. Record the valve locations or landscape zone identification for each station on the label inside the cabinet door.
Master Valve Wiring
1. Connect one lead from a 24 VAC Master Valve to the
controller Master Valve lead (Wht/Orn).
2. Connect the other Master Valve lead to the controller
common (white) along with the valve common leads.
CAUTION: If a master valve is not being used, be sure
to tape the end of the Master Valve lead to prevent any
possibility of "shorting."
