Occupied and Unoccupied Periods
Important — Before you Begin
When using unoccupied modes, Auto fan speed must be
selected. Manual fan speed should not be used for unoccu-
pied operation. Auto Fan speed must be used to prevent the
system from entering the coil freeze protection cycle or in
heating, the high-pressure protection cycle. (See Advanced
Setup 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 tem-
perature from 7:00 a.m. to 5:00 p.m. Monday through Friday
and for the remainder of the day have an alternate or set-
back 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 al-
ternate temperature set point.
NOTE: If one occupied period starts and stops within anoth-
er 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.
Select the maximum number
of occupied periods to be
used on any one day.
