A:Answer Are we taking about the display or the AC?
Display:, pending where the thermostat is location, I experienced the glas Located in the family room to go on by it self. (display only) More during the evening because of the TV, the glas acting if someone is in front of it. (Reflection, brightness and shadowing from the TV) The one in the master bedroom much less.
Fan: the glas has a Unique feature that monitors the air quality and if this feature is turned on the glas will turn on the fan to improve the air quality.
