Comf. or econ.
Default value:
Comfort
Comfort or Economy Mode
Sets the operation and interaction mode of the heat pump with the auxiliary heat.
Comfort mode
: In Heating mode, if the heat pump is not able to satisfy the heating
setpoint, the auxiliary heat gets energized to satisfy the same heating setpoint.
Economy mode
: In Heating mode, if the heat pump is not able to satisfy the heating
setpoint, the auxiliary heat gets energized to satisfy only when the temperature drops
2.0°F (1.1°C) below the heating setpoint. Selecting economy mode adds a deadband
between the heat pump & auxiliary heat in heating mode. The actual temperature
maintained will be lower than the true heating setpoint to maximize the heat pump
operation. When the outdoor air temperature drops below the low balance point, the
deadband gets eliminated and the auxiliary heat maintains the true heating setpoint
alone.

: In Heating mode, if the heat pump is not able to satisfy the heating setpoint,
the auxiliary heat gets energized at the same time as the heat pump stage. Typically
applies when the air handler heat pump coil is installed before the auxiliary heat (all
electric systems).
On
: In Heating mode, if the heat pump is not able to satisfy the heating setpoint, the
auxiliary heat gets energized and the heat pump is cut off. Typically applies when the
air handler heat pump coil is installed after the auxiliary heat (add on systems) There
is a 2 minute delay to restart the heat pump when the auxiliary heat is shut down.
