Important -- Before you Begin
When using unoccupied modes, Auto fan speed must be
selected. Manual fan speed should not be used for unoc-
cupied operation. Auto Fan speed must be used to pre-
vent the system from entering the coil freeze protection
cycle or in heating, the high-pressure protection cycle.
(See Advanced Set-Up Section for fan speed selection.)
If different heating and/or cooling temperature set points
are desired Monday through Friday, at different times of
the day, two occupied periods must be programmed. To
adjust set points and times for the two occupied periods:
If the space to be controlled should have a designated
temperature from 7:00 a.m. to 5:00 p.m. Monday through
Friday and for the remainder of the day have an alternate
or setback temperature set point set to stop at 5:00 p.m.,
program the occupied (2) mode at 12:00 a.m. to
12:00 a.m. at the alternate temperature set point.
NOTE: If one occupied period starts and stops within an-
other occupied period the lower occupied number has
priority.
If additional setback is desired for Saturday and Sunday,
program occupied (1) from 12:00 a.m. to 12:00 a.m. for
both Saturday and Sunday at the desired temperature.

Programming Notes
• If only one Occupied period is selected in Step 1 on
this page, 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.
• 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.
