READ THESE INSTRUCTIONS CAREFULLY AND COMPLETELY 

READ THESE INSTRUCTIONS CAREFULLY AND COMPLETELY BEFORE PROCEEDING WITH THE INSTALLATION.

BEFORE PROCEEDING WITH THE INSTALLATION.

•  Meets the requirements of the ASHRAE 62.2 standard for ventilation. 
•  Supplied with an outdoor temperature sensor which mounts in the fresh air duct.
•  Has three selectable Climate Zones with unique ventilation inhibit parameters for the selected    
   climate.
•  Monitors up to four exhaust appliances within your home to adjust ventilation needs based on 
    total appliance operation.
•  Can provide Make-Up air in response to an exhausting appliance.
•  Can utilize an exhaust fan to drive ventilation independent of the central HVAC fan to save energy. 
•  Continuously monitors indoor Relative Humidity:
 

    -   Lower excess indoor humidity during hot muggy days by reducing ventilation during 

 

        these  periods to prevent discomfort and mold growth in the home. 

 

    -   Reduce condensation and corrosion of the heat exchanger.

The Field Controls Fresh Air Ventilation Control 

TM

 (FAVC) is designed to provide fresh air ventilation 

year-round, keeping energy conservation, indoor air quality and comfort in mind. The FAVC delivers 
ventilation along with many additional features:
