Abstract
A method and system for improving indoor air quality by controlling the circulation of air by a system fan of a conventional environmental control system in order to achieve a minimum circulation cycle. The method and system prevent nuisance short cycling of the system fan by extending the circulation cycle when the method and system predict the system fan will be activated by the environmental control system for heating or cooling shortly after the termination of the controlled circulation.
