Irritrol Kwik Dial Controller:

KwikDial®, the ideal residential controller from Irritrol, offers a unique
combination of sophisticated features and simple operation. Excellent
scheduling flexibility is provided by its automatic, semiautomatic
and manual operations, a wide range of watering intervals, and the
ability to make percentage changes to watering duration for seasonal
adjustments. An easy-to-use dial and four large push buttons make
programming simple, and an optional remote system with station
“start/pause/resume/ off” capability enhances ease of maintenance.
Peace of mind is ensured by the controller’s electrical surge protection;
a self-diagnostic, electronic circuit breaker; and built-in memory that
maintains time, date and programming information for 24 hours in
the absence of AC power.
