(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.
C
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.
1
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."

Instructions for Attaching Plug-In Transformer.
Prior to plugging the transformer into a 120 VAC wall receptacle, insert the wire through the 1/4" hole in the lower left corner of the controller, tie an overhand knot in the wire about 5" from the end (inside the case). This will prevent inadver­tent disconnection of the wire. Connect one or­ange wire to the wht/red wire with the "line in­put" label and connect the other orange wire to the wht/brn wire with the "line input" label. (See Figure 4)
Now, plug transformer into wall receptacle. (Note: International transformer is not "plug-in" type.)

Electrical System Checkout
1. Rotate the STATION dial counterclockwise to position REST at the top directly un-
der the Station pointer.
2. Pull all pins on the HOUR and DAY dials to the "out" position.
3. Put the MODE switch in the AUTO position.
4. Make sure transformer is plugged into a wall receptacle.
5. Adjust each station TIME control to the 5 minute mark. (See Figure 6.)
6. Rotate the STATION dial (counterclockwise) to position Station 1 under the pointer.
Watering should commence shortly as the automatic mechanism latches with the Sta­tion dial.
The 5-minute interval should provide sufficient time to observe control valve operation. If more time is required, simply adjust the timing knobs as necessary. The controller will advance through each station, in sequence, providing opportunity to observe each circuit for proper operation.
Upon satisfactory checkout of the system, proceed to adjust the controller clock.
SETTING THE CONTROLLER
With the main power ON, proceed to adjust the clock for the correct time and day.
1. Put the MODE switch in the OFF position.
2. Rotate the HOUR dial (clockwise only) to position the current time opposite the
TIME pointer at the top of the panel. Observe the dial for the correct AM or PM numer­als.
4
Example: If the correct time is 1:35 PM,
position the dial such that the TIME pointer will point midway between the 1 and 2 numerals on the PM side of the dial. If a more precise adjustment is de­sired, the best procedure would be to push-in the pin corresponding to the up­coming hour (in this example, the 2 PM pin) and on that hour, slowly rotate the dial until you hear the "click" of the micro-switch.
3. Proceed to set the present day by ro­tating the calendar DAY dial to position the correct letter opposite the DAY pointer at the bottom of the dial.
4. Next, rotate the STATION dial in a counterclockwise direction to position REST at the top under the STATION pointer. This completes the controller clock setting.
SCHEDULING AUTOMATIC OPERATION
Make sure the HOUR and DAY dials are set to the correct time and that all pins are in the "out" position.
1. Push in the pin(s) corresponding to the day(s) on which watering is desired. Re­member, each DAY pin represents a 24 hour period beginning at midnight.
2. Next, select the desired starting time(s) and push in the corresponding pin(s) on the HOUR dial.
3. The first mark (square dot on the station dial) is the minimum time setting and rep­resents approximately 3 minutes. The small white arrow moves with the knob for visual indication of each setting. (There will be no valve output when the arrow is positioned between "off" and the "square dot.'') The ratchet notches represent 1 minute incre­ments for precise settings. The OFF position at each timing dial, omits the station from the schedule.

NOTE: The minimum accumulated cycle time re- quired to prevent a second start within a given hour is 20 minutes. Conversely, the maximum accumulated time to permit a cycle start on a consecutive hour is 55 minutes. Total cycle time of more than one hour is permissible.
NOTE: It takes about 20 minutes for the hour dial pin that started a watering cycle to move off the cycle-start switch behind the face panel. To make sure the RC-4Bi will not start another cy­cle when the combined running time of stations 1 through 4 is less than 20 minutes, the con­troller will stop at the non-existent station #6 po­sition and time out 20 minutes before returning to "REST."
This completes the automatic setting of the con­troller. Move the MODE switch to the AUTO po­sition. The controller will now automatically con­trol the landscape irrigation according to the
SEMI-AUTOMATIC OPERATION
The controller may be operated at any time in a semi-automatic mode simply by turn­ing the STATION dial counterclockwise to position the desired station at the top, just ahead of the Station pointer. Allow the automatic mechanism to advance into the de­sired timing zone. The selected station will operate for the time set on the dial, after which, the remaining stations will follow in sequence until the REST position again ap­pears under the Station pointer.
RAIN SHUTDOWN
There may be occasions where it is desired to interrupt all landscape irrigation. Condi­tions such as rainy weather, system repair, landscape renovation, or other excavation work. The temporary shutdown of the system is accomplished by moving the MODE switch to the OFF position. This eliminates controller output to the valves without inter­rupting the controller timing circuitry. The controller will not operate either automati­cally or semi-automatically. A summary of the operating instructions is provided on the label inside the controller door.
MAINTENANCE
The controller is designed to provide years of trouble-free service. The controller re­quires no preventative maintenance or lubrication. Should trouble occur, refer to the Troubleshooting chart for possible remedies, or contact your local authorized Rain Bird dealer.
