ABSTRACT:
A control system for use with an attic ventilation fan operates to reduce heat buildup during the summer months and also to prevent frost buildup during the winter months by eliminating the cold, moisture-laden, air from the attic. A summer control unit is provided to eliminate the hot air and a winter control unit operates without the need of a humidistat to evacuate the moisture laden cold air during the winter months.
