When installed in an HVAC system, the HSC Controller extends the fan’s running time by up to 8 minutes. Some manufacturers of HVAC systems program the fan to stay on for 90 seconds, but recent studies have shown improved energy efficiency when the fan runs longer. By keeping just the HVAC fan on for a longer period of time after the heating or cooling cycle, the system makes use of heating or cooling that would have been wasted.
