Explanation
Allows you to specify an auxiliary heat
lockout temperature. If the outdoor ambi-
ent temperature is greater than the
selected auxiliary heat lockout tempera-
ture, the auxiliary heat (W1 and W2) out-
puts are not energized.
If OFF is selected, the heating equipment
cycle always starts with the heat pump,
regardless of the outdoor air temperature.
If you select a lockout temperature, and
the outdoor air temperature is less than the
selected temperature, the heating cycle
starts with the AUX Heat source. If the out-
door air temperature is equal to or greater
than the selected temperature, the heating
cycle starts with the heat pump.
Used to determine how quickly the com-
pressor ramps up to meet setpoint
Allows you to adjust the heating airflow
CFM by plus/minus 5% or 10%
Allows you to adjust the cooling airflow
CFM by plus/minus 5% or 10%
Adjusts the indoor fan motor maximum
speed in Cool mode. The Normal option is
the default. The Humid option reduces the
max fan CFM by 10%. The Dry option
increases the max fan speed by 10%. The
fan speed in Heat mode is not affected by
this setting.
If necessary, you can increase this tem-
perature setpoint for more aggressive
defrost operation.
Enables or disables the Demand
Response feature
When Demand Response is active, the
setpoint updates to the selected
temperature value or the equipment shuts
down. The setpoint can be raised or low-
ered when the event is active,
but the temperature selection differential
must be maintained.
