It is also possible to set a programmable period (from 1 to
31 days) for Off, after which the system will automatically
return to automatic irrigation. This is useful for halting
irrigation when weather fronts or conditions are expected
to persist for several days.
To set a programmable Rain Off duration: turn the dial to
the Off position.
While the controller is in the OFF mode, press the + button
and hold for approximately 3 seconds.
The Days Left: xx display will appear. Release the + button,
and then use the + or – button to set the desired number of
Days Off before automatic irrigation will resume.
Turn the dial back to Run immediately (the days off setting
will time out if it is left more than 5–6 seconds).
The display at the Run position will then show the number
of days for the Off setting. This display will count down
each day, showing the remaining days until automatic
irrigation will resume.

The ACC controller can be reset, erasing most
programmed information. There are 5 different levels of
Reset command available, but once any of them is chosen,
the information will be permanently erased.
These operations are not reversible!
Reset should only be performed if:
a) a “clean start” is desired for programming purposes, or
b) if directed to do so by Hunter Technical Services as a
troubleshooting technique.
To Reset the ACC controller: Turn the dial to the Run
position.
Press and hold the Programs button, and at the same
time press in the recessed Reset button with the tip of
a ballpoint pen. Release the Reset button and continue
holding the Programs button until the Reset Memory
screen appears (then release the Programs button).
