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 programming. Details on how to implement these features will be described in the step-by-step instructions 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 PROGRAM 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 display will blink to indicate the need for a new battery. Install a 9-volt alkaline battery to the battery
