Battery Installation & Armchair Programming
Installing a 9V battery (user-provided) serves two important functions:
first, it enables the Rain Dial-R to be fully programmed prior to
installation, and second, it keeps the control module synchronized with
current time and date during a main power interruption lasting up to 24
hours.
Note: The battery is not capable of operating the sprinkler valves. Main
AC power must be applied to the controller to enable operation.
The control module is designed to be easily removed for complete
programming in a more convenient setting, such as your favorite
armchair. To remove the control module, simply unplug the ribbon cable
connector from the printed circuit board, then carefully remove the
module from its snap-in hinges. The Rain Dial-R features non-volatile
memory, which keeps the programming information intact, even if the
battery dies or is disconnected.
Installing the Battery
1. Open the controller door.
2. Pull the control module open by grasping it from the right edge
(press the module release tab on the outdoor model).
3. Press down and outward on top of the battery compartment cover to
remove. See Figure 1.
4. Attach the battery clip to a 9V Alkaline battery.
5. Stow the battery into the compartment and reinstall the cover.
6. The display will begin flashing 12:00 AM. (Press any button to halt.)
Note: To begin setting up a watering Program, refer to
“Basic Programming Procedures” on page 10.
Caution: To avoid hazards from improper battery type
installation, always replace the battery with the same or
equivalent battery type.
Always dispose of used batteries properly, as recommended by
the battery manufacturer.
