The AirCycler® FRV Furnace Fan Timer is a simple solution for meeting whole house ventilation standards. In one user-friendly controller, the AirCycler® FRV integrates with the central furnace fan and existing ductwork to deliver fresh air throughout the home. Using the programmable ON/OFF timer the AirCycler® FRV allows for the enabling and disabling of the central furnace fan and motorized damper to better control ventilation. 


  • Helps meet ASHRAE 62.2 ventilation standards
  • Enhances whole house filtration system
  • Interlock HRV/ERV systems for use with existing ductwork
  • Enhanced temperature and humidity control
  • Comes factory preset with most applications
  • Retains programming during power failure
  • LCD display provides current status and troubleshooting



The AirCycler® FRV is a furnace fan timer and ventilation controller with an output for operating a motorized fresh air damper*. This product provides whole house supply ventilation through central furnace fan integration.

During installation the AirCycler® FRV is programmed with the amount of ventilation desired. Through intregration with the central furnace fan, the AirCycler® FRV is able to detect when the central fan operates for regular heating and cooling cycles- during which time air is being circulated throughout the home - and compares that operation time with the total ventilation time set during installation.

If the ventilation requirements have not been met, the AirCycler® FRV automatically powers on the central fan until the desired ventilation time has been reached. Each time the AirCycler® FRV powers on the central fan it also opens a motorized damper to allow fresh air to enter the home. Using the programmable ON/OFF settings for both the fan and the damper, the central fan is not running continuously and energy efficiency is maintained.

By mixing/circulating air from each room, the AirCycler® FRV allows for an “averaging” of air temperature and humidity throughout the home and improves air quality by introducing fresh air and eliminating stagnant air. The AirCycler® FRV works independently of the thermostat.
