Rain Bird CRC-8A Programming And Operating Instructions

CRC-8A, CRC-6A, CRC-4A The CRC-A Controller has some important features you should be aware of before you begin pro- gramming. Details on how to implement these features will be described in the step-by-step instruc- tions on the following pages. • The CRC-A has a DUAL PROGRAM capability which allows watering of grass areas more often and/or on different days than shrub areas. • The CRC-A has a PRESET PROGRAM which is built into the controller at the factory. If you do not wish to establish your own program, after updating the clock, the controller will operate each station for 10 minutes each day beginning at 8 A.M. • The CRC-A has a DEFAULT MODE in which the controller will revert back to the PRESET PRO- GRAM should your own program be lost due to a prolonged power failure. • The CRC-A has a 14 - day cycle. After completing watering on the 14th day, it will automatically repeat the cycle beginning with day 1. • The controller has a backup battery circuit which will keep your program from being lost for up to 24 hours in the event of a power failure. Should the battery you supply go dead the entire dis- play will blink to indicate the need for a new battery.

After Programming Is Complete Once you have completed programming your CRC-A controller, you can return it to displaying the correct time of day as it waits in the automatic mode for the correct time to start. To do this, Tidbits and Items to remember: The nine-volt, alkaline battery you supply will protect the program memory for up to 24 hours during a power outage. Without a battery, even a momentary power interruption (fractions of a second) will cause memory loss. Studies have shown that such momen- tary power interruptions happen many times per day in the average household. Re- member to install a nine-volt alkaline battery to the battery clip (in the bottom compart- ment of the controller cabinet) as noted in the installation instructions for this unit. In the event of a long power outage completely using up your battery's power, the de- fault program will be in effect when power resumes. This default program will automat- ically operate a special "A" program only, and water every station of the controller once a day for 10 minutes each. (See the DEFAULT PROGRAM section at the back of this manual for details.) In item #2 of this manual "What time to start..." you learned how to set, how to change, and how to add starting times for your CRC-A controller to begin a cycle. If you wish to ELIMINATE A START TIME from a program, the procedure is quite simple. First, press the "Program A" or "Program B" key so the controller knows which program you desire to change. Then press the "Water Times Per Day" key one, two, or three times until the start time you wish to eliminate appears in the display. Now press either the "Change Time" up or "Change Time" down key until the time in the display reaches the blank point at midnight. The start time is now eliminated. If you were eliminating this start time and the controller was in a cycle, touch the "Monitor While On" key to get back to a display of the cycle's progress. If the con- troller was not operating a cycle, simply touch either the "Set Clock Hour" or "Set Press either SET CLOCK HOUR SET CLOCK MINUTE or and your programming is complete.

These program tables may be cut out and affixed to the inside of the controller door for handy reference. 1.

and television reception. It has been type tested and found to comply with the limits for a Class B computing device in accordance with the specifications in Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interfer- ence will not occur in a particular installation. If this equipment does cause interfer- ence to radio or television reception, which can be determined by turning the equip- ment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • reorient the receiving antenna • move the controller away from the receiver • Plug the controller into a different outlet so that controller and receiver are on dif- • ferent branch circuits If necessary, the user should consult the dealer or an experienced radio/ television technician for additional suggestions. The user may find the following booklet pre- pared by the Federal Communications Commission helpful: "How To Identify and Resolve Radio - TV Interference Problems" This booklet is available from the U.S. Government Printing Office, Washington, D.C.
