The indoor unit’s fan only blows air when the coil has warmed to the desired temperature. An energy-saving measure, it also prevents drafts of cold air at start-up.

This sensor scans the room and adjusts temperature and airflow automatically. Maintain consistent comfort by eliminating cold and hot spots.
