This is a user selectable value for when dual fuel “Restricted” mode is enabled. The
temperature selected is the compressor lockout temperature. When the outdoor
temperature is above this setpoint, only the heat pump will run for heating. When
the outdoor temperature is below this setpoint, only the furnace will run for heating.

The Recover feature is active only when “Schedule” is enabled and the schedule
mode is set to “RUN”
Recovery operation, when enabled, will start the cooling or heating system so
that the desired comfort temperature is reached by the next scheduled set point
time. The advance start time calculation is a learned process that is recalculated
and adjusted each day until the room temperature is at the target temperature at
the schedule time. When the thermostat is in Recovery mode the display will show
“Recov”.
Recovery works for all scheduled periods (1-4) and in HEAT, COOL or AUTO
modes. While in Recovery the Aux-Heat stage will not engage.
The maximum Recovery time is one hour.

separation.
