ft no is selected, as in previous steps, flashing prompts for input will appear
for start and stop times for Occupied 1. If more than one occupied period
was selected in Step 1 on page 3, then cool/heat set points, and start/stop
times for additional occupied periods will be prompted.
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.
