1.0 THEORY OF OPERATION
1.1 OPERATION DETAILS
The AirCycler® g2 Furnace Fan Timer is integrated with the home's central furnace fan so that any time the central
fan is turned on by the thermostat to provide heating or cooling, the AirCycler® g2 opens the motorized damper to
let in a measured amount of fresh air. The fresh air is then distributed uniformly throughout the home through the
existing ductwork.
When ventilation requirements are met, the damper is closed to prevent over-ventilation.
Should regular heating and cooling cycles not run long enough to meet the desired or required ventilation, the
AirCycler® g2 can turn on the smaller and more economical bathroom exhaust fan (or other exhaust fan) through the
optional FanConnect™ Switch.
With no need to run the large central fan to provide additional ventilation, homeowner complaints of cold air or noisy
operation are eliminated and efficiency is drastically improved.
