Sets the minimum separation between heating and cooling
setpoints. Attempts to lower the cooling below the heating setpoint
by this amount will PUSH the heating setpoint down to maintain
this separation. Same for setting the heating setpoint above the
cooling setpoint, it will PUSH the cooling setpoint up to maintain this
separation.

Thermostat Recovery Operation
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.
