Comp OAT Low
(AV17) is the outside air temper-
ature value, below which the compressor is locked
out (when lockout is enabled). The user interface
min./max. limits are 5 and 50 degrees, with a de-
fault value of 40 degrees F.

is a substitute for manually entering sched-
ules. When IOA is enabled, it “learns” a schedule
by sensing motion.
The IOA turns occupancy mode on (for 15 min-
utes as a default) whenever motion is detected.
tion does not modify the schedule. For IOA to
learn/modify the schedule, it must detect motion
at least once during four consecutive “quarter
windows” (1800 seconds or 30 minutes is the
default for a full window). To change the schedule
(with the default setting) after an initial detection,
motion must also be detected at least once during
the second quarter of the window (approximately
minutes 8–15), third quarter (minutes 16–22), and
fourth quarter (minutes 23–30).
When IOA is enabled, schedules manually entered
in the Schedule menu will be overridden and
modified. During a learned “occupied” time, if no
motion is sensed for 15 minutes (default), IOA will
switch the system to unoccupied. (To adjust the
motion sensing time, see
.)
After IOA creates a particular schedule, it makes
further modifications as needed. If no motion dur-
ing a scheduled On time is detected two consecu-
tive weeks on the same day of the week, that On
time is cleared. (For example, if no one is present
in a room for two consecutive Tuesdays, then the
scheduled IOA start time for Tuesday is cleared.)
When
Optimum Start
is enabled, the FlexStat
soon “learns” the amount of time required to
reach the setpoint from the setback/setup tem-
perature. It will then adjust the actual start time
needed to reach the desired setpoint at the begin-
ning of the scheduled On times. It will also make
seasonal temperature adjustments if an outside air
temperature sensor is connected appropriately.
