AUXILIARY CONTROLS
With power to the unit and Freeze Sentinel activated,
the unit automatically provides heat without user inter-
face. This prevents potential plumbing damage by turning
the heater and indoor fan ON at 41
o
F and then OFF once
the room temperature reaches 46
o
F.
When Heat Sentinel is activated, the unit automatically
provides cooling without user interface. This prevents an
excessively hot room by turning the air conditioner ON
at 85
o
F and then OFF once the room temperature
reaches 80
o
F.
In the default setting for Mode 3, Heat Sentinel is off,
Freeze Sentinel is on.
NOTE: Note: Heat Sentinel is the 2nd instance of mode 3.
With Constant Fan activated, the indoor fan will run
continuously as long as there is power to the unit.
This will override any fan commands provided by the
remote thermostat.
The default setting for Mode 4 is OFF.
This setting is used when the unit is installed with more
restrictive ductwork where additional airflow is needed.
See airflow table located in the Owner's Manual.
This increases the fan speed to ensure proper circulation.
The default setting for Mode 7 is OFF.
This electric heat option functions only on the AZ95 model.
When this option is ON
,
heat pump operation is locked
out, causing the unit to provide only electric resistance heat.
The default setting for Mode 8 is OFF.
When Heat Boost is ON and outside temperatures are
between 25
o
F and 46
o
F, supplementary electric heat to
the heat pump operation to help maintain a consistent,
comfortable room temperature.
The default setting for Mode 9 is OFF.
This setting is used to configure the unit when the circuit
board is replaced. The first time the unit is powered after
a service board is installed, the unit will automatically enter
this mode. The UI will read “P1.” Press the “+” pad until the
number matches the engineering revision as shown. The
engineering revision is the last number in the model num-
ber. Press “Aux” to save and exit. The engineering revision
may be adjusted after the first power cycle using AUX SET.
Press MODE until “P” appears in the first digit, and follow
the steps described above.
