Make-up Air Sensors

Make-up air sensors are air pressure sensors that sense a change in air pressure within the exhaust duct of an exhausting device, such as a kitchen range hood, clothes dryer, central exhaust system, etc. It transmits a signal to a make-up air system, such as the Fresh Air Ventilation Control ventilation system, in order to provide make-up air for the exhausting device. The P-Sensor may also be used in a stand-alone passive make-up air system to control a 24V fresh air damper (FAD) that is ducted to the exterior of the structure.

Better Control in Any Environment. The Fresh Air Ventilation Control (FAVC) can monitor up to four exhaust fan appliances like a bathroom fan, range hood, clothes dryer and gas fireplace. Our C-Sensor relays data back to the FAVC which can then adjust fresh air intake. Each sensor works independently or in concert with the others to monitor environmental changes, providing increased or decreased ventilation as needed.C-Sensor relays data back to the controls, like the Fresh Air Ventilation Control (FAVC), which can then adjust fresh air intake.

The C-Sensor senses the operation of air-exhausting devices, such as range hoods, clothes dryers, bathroom fans, central vacuum systems, etc. It acts as a switch to provide a 24 VAC input signal to the Fresh Air Ventilation Control (FAVC), which then operates the fresh air damper (FAD) and activates the HVAC central fan. Fresh, outside air is then drawn into the house, providing make-up air for the exhausting device(s). The C-Sensor may also be used in a stand-alone make-up air system to control a 24V fresh air damper.

Make-up air sensors should be installed by a licensed contractor. Find a contractor in your area.
