WEBINAR: Advanced Controls for Residential HVAC Fan

This study investigated the energy savings potential of a commercially available fan controller designed to be installed in residential HVAC systems. The device lengthens the fan-off delay, or the amount of time the air handler fan continues to operate following a cooling or heating cycle. As Minnesota is in a heating-dominated climate, most of the market characterization, modeling, and field analysis focused on heating season performance, but the same analysis techniques were also applied to cooling season data.
