Pre-comfort Recovery
This thermostat is equipped with a ‘Pre-comfort Recovery’ system that will activate the heating or cooling in
advance of the actual set program time so that the room will be at the desired temperature at the start of the
comfort program time.
It is normal for the system to be activated earlier (up to one hour) than the actual set program time. When
the thermostat is in ‘recovery’, the OVERRIDE symbol will be flashing.
The Pre-comfort Recovery can be disabled if desired. Please refer to "Optional Settings" on pages 15 and 16.
