The Digi 322 controls are one, two and four

channel electronic time switches with 365-

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.

TO THE INSTALLER:

1. Read operating instructions carefully.

2. Check the input voltage ratings marked on the

unit to make sure this product is suitable for

your power supply and application.

3. Disconnect power supply prior to installation to

prevent electrical shock.

4. Damage to the relay-contacts caused by short

circuiting will void warranty.

5. Wire in accordance with National and Local

electrical code requirements.
