PROGRAMMING NOTES
• If only one Occupied period is selected in Step 1 on
page 3, Occupied 2 and 3 programming steps are
skipped. Further, if only 2 occupied periods are
selected, Occupied 3 programming steps are skipped.
• Heat and Cool set points for Occupied 1 are the same
for every day of the week. Heat and Cool set points for
Occupied 2 and 3 can be adjusted differently for each
day of the week, if desired.
•
If the start time is set later in the day than the stop
time
, the program will run from the start time to mid-
night and from midnight to the stop time on the same
day.
For example: 9:00pm start, 8:00am stop, on
Monday. In this example the program will run from
12:00am Monday to 8:00am Monday and again from
9:00pm Monday to 12:00pm Monday.
• The Unoccupied settings take effect at all times when:
(
1
) the program is on
and (2
) the current time is out-
side a preset occupied period. For this reason start
and stop times are not necessary for unoccupied.
• If the
same
start and stop times are programmed in for
an occupied period, then it will run 24 hours.
• If one occupied period starts and stops within another
occupied period, the lower occupied number has prior-
ity.
For example: If Occupied 3 is programmed to be
“on” 24 hours, and Occupied 2 is programmed to run
that day, then Occupied 2 settings will take over from
Occupied 3 between Occupied 2 start and stop times.

additional occupied periods will be prompted.
