from 0 to 65° F (–17.8 to 18.3° C) or can be completely disabled.
Note: You need an Internet connection for this feature to operate
properly.
Allow HP with Aux Heat If you select Yes and there is a source
d
of auxiliary heat, it will turn on in addition to the heat pump. The
heat pump will be energized for the first 30 minutes. If, after 30
minutes, the set point has not been met, the auxiliary heat will be
energized to assist the heat pump in meeting the load.
If you select No, the heat pump will be energized for up to 2
hours. If after 2 hours the set point has not been met, the thermo-
stat will shutdown the heat pump and energize the auxiliary heat
to meet the set point. This option should also be used for installa-
tion where the heat pump evaporator coil is upstream from the
source of auxiliary heat.
This setting is only available when the Comp to Aux Temp Delta
and Comp to Aux Runtime settings are both set to Auto (default).

source. If you have selected a heat pump as your primary source, this
feature allows you to configure the 1st stage of auxiliary heat connected
to the system.
Furnace Type Allows you to configure the type of furnace. This
d
helps the thermostat optimize its algorithms based on the type of
fuel and typical characteristics of the chosen system. Choose the
option that best represents the type of heating system installed.
Heat Fan Control Configures the furnace fan to be controlled by
d
the thermostat or the HVAC system during heat cycles. Normally
the HVAC system controls the fan during heat cycles.
