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 differ
ently for weekdays and weekends, 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 midnight 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 outside 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 num
ber has priority. For example: If Occupied 3 is pro
grammed to be “on” 24 hours, and Occupied 2 is
programmed to run that day, then Occupied 2 set

tings will take over from Occupied 3 between
Occupied 2 start and stop times.
