Apparatus for modifying the temperatures of upper and lower level building interiors including air delivery means, heat generating means and first and second temperature sensing means for sensing the temperatures of the upper and lower level interiors. Air is delivered from the upper level interior to the lower level interior when there is a first sensed temperature differential between the interiors and the air is heated when the sensed differential drops to a predetermined lesser magnitude.
