A ventilation controller with a manual override is located on a central air handler fan that is located in an accessible location
Air flow is produced when central HVAC fan is energized (set thermostat to “fan”)
All of the exhaust fans are wired to one labeled switch at the electrical panel
An electronic controller operates an exhaust fan, a mechanical damper on a fresh air intake, and the central heat pump’s fan, which draws in fresh air through the damper and distributes it in sync with exhaust fan operation for balanced fresh air.
Continuously-operating ventilation & exhaust fans include readily accessible override controls
Cool air flow is produced when the cooling cycle is energized (set thermostat to “cool”)
