Anywhere Programming
The Rain Dial control module is designed to be easily removed for complete
programming in a more convenient setting, or service. The module's battery
power holds the program until the module is re-electrified. To remove the
module, pop the module up as if you were going to replace the battery. Note
the multi-pin plug on the upper left-hand face of the terminal board. Grasp the
"wiring harness" closest to the plug and pull it out from the terminal. Then
unsnap the module from the 2 hinge points. After programming or servicing,
reinstall the module by reversing the steps above.
Fail-Safe Mode
If the battery fails during a power interuption, your program will be lost. When
power is restored, the Rain Dial controller automatically defaults to its fail-safe
mode. Upon restoration of power, the fail-safe mode returns to Sunday at
12:00 p.m. and the clock runs from that point. Unless the controller is reprogrammed,
it will run each valve for 10 minutes, beginning at 7:00 a.m. These
10 minute waterings are repeated every 24 hours. This feature is designed to
protect lawns and plants from drying out from outages that occur while you are
away for a prolonged period of time. NOTE: In freeze areas, disconnect the
controller while you are away to prevent activation of the fail-safe program.
