Abstract

A system for lessening the temperature differential between the upper and lower levels of a building including sensing means for sensing the temperatures of both of said levels, air delivery means for delivering air between the level interiors, and control means for activating the air delivery means when a temperature differential of a predetermined magnitude is sensed by the sensing means.
