PROGRAMS
The Digi 42/2 will accept up to 42 programs
A program consists of:
1. An ON or OFF command
2. Time of day (Hour
and
Minute)
3. Single day or multiple days
A program is required for each ON event, and a program is
required for each OFF event.
NOTE:
MULTIPLE ON OR OFF EVENTS MAY BE PROGRAMMED.
For example, Program 1 may turn the office air conditioning ON at 8AM
Mon.-Fri. Program 2 may turn the air conditioning OFF at 5PM Mon.-Fri.
If someone is working late, they may press the override key to turn on
the air conditioning. If they forget to press the override key again when
they leave, the air conditioning will stay on all night (or all weekend).
To prevent this from occurring,
additional OFF times may be pro-
grammed.
• Program 3 can turn the air conditioning OFF at 6PM.

• Program 5 can turn the air conditioning OFF at 8PM., etc.
