FAS (Fresh Air System) - The Fresh Air Damper is connected to the outside via duct and an intake air hood. It is then connected to the central HVAC system return. A Healthy Home System Control (HHSC+) is programmed to open the control on a schedule in conjunction with the central fan. The HHSC+ can also be connected to the 24v (FSE) Flue Sentinel Damper control and will open when the flue damper is open. As outside air enters the system through the damper, it is mixed with conditioned air and distributed throughout the house via the central ductwork. The Fresh Air Damper is closed when the HHSC+ signals that ventilation demands are satisfied or the call for fire has ended. It can also be closed manually from the HHSC+.Model FAS-6 Includes:Healthy Home System™ Control:
