Weekdays
The Digi 322 controls are one, two and four
channel electronic time switches with 365-
day, 7-day and 24-hour programming. The
channels are freely programmable with a total
of 322 schedules. The load status, time of day,
and date are displayed on a large LCD read-
out.
Functional Description
The Digi 322 time control can be programmed as
24-hour, 7-day, or a 365-day schedule of individ-
ual holidays or holiday/vacation periods. This
control incorporates a calendar through the year
2090 and also includes automatic leap year
adjustment. The annual daylight savings/stan-
dard time changes can be programmed to occur
automatically each year through 2090.
Holidays that occur on the same date each year
(July 4) need only be programmed once—they
will be stored and will be executed each year
until 2090. Holidays that occur on a different date
each year (Labor Day) should be entered with
the 1X key (one-time). They will be automatically
neutralized after their occurrence, therefore, they
need not be deleted when programming the con-
trol next year. These features minimize the annual
programming considerably.
Please read these operating instructions carefully
so that you will be able to take full advantage of
the functions offered by the Digi 322 time control.
