Auxiliary Heat (Heat Pump Only) Setup
AUX HEAT SETUP
AUX HEAT:
DELAY (MINS): 60
COMP OAT LOW: 40° F
COMP LOCKOUT
For HPUs, auxiliary heat can be set for none, with
compressor lockout, or without compressor lockout.
The Delay time controls how long the space temper-
ature must be below the auxiliary heat’s start tem-
perature before auxiliary heat will turn on. (For more
details, see the Auxiliary/Emergency Heat section
under Sequence of Operation (BAC-1xx63/1xxx63) in
the FlexStatApplicationGuide.)
CompOATLow (AV17) is the outside air tempera-
ture value, below which the compressor is locked out
(when lockout is enabled). The user interface min./
max. limits are 0 and 70 degrees, with a default value
of 40 degrees F.

MIN POSITION: 0%
CNTRL (0–100%): 2–10 V
ECON ENBLE TEMP: 55° F
LOW LIMIT ALARM: 45° F
MODULATING
If the Economizer option is selected when there is
no mixed air temperature sensor connected, a Low
Limit Alarm will result. See Alarms on page 23. A Low
Limit Alarm will close the dampers, open the hot
water valve if present, and shut the unit down.
Outside Air Damper Low Limit maintains a mini-
mum mixed air temperature. It will override econo-
mizing, DCV, or other calls for ventilation if low
temperature threatens to damage equipment. For
modulating economizers, OAD Low Limit is enabled
by default but can be disabled if desired (such as for
an AHU with gas heat).
CAUTION
Do not disable the OAD Low Limit if coils or
other equipment may consequently be damaged
by low temperatures.
