AIRCYCLER® G2-K INTRODUCTION
The AirCycler® g2-k Whole House Mechanical Ventilation System includes the AirCycler® g2 Furnace Fan Timer,
FanConnect™ Bath/Fan Light Switch with remote fan control, and a motorized fresh air damper.
The AirCycler® g2 is a furnace fan timer and ventilation controller with outputs for operating a motorized fresh air
damper and the FanConnect™ exhaust fan switch*. This product provides whole house supply ventilation through cen-
tral furnace fan integration as well as whole house exhaust ventilation.
SAFETY CONSIDERATIONS
Read and follow manufacturer’s instructions carefully. Follow all local electrical codes during installation. All wiring
must conform to local and national electrical codes. Improper wiring or installation may result in personal injury or
product and property damage.
INSTALLATION CONSIDERATIONS
The AirCycler® g2 requires 24VAC (R and C terminals) to be connected for proper operation. The controller will not
operate without these two connections.
The wires (R, C, & W ) from the air handler to the thermostat can run parallel with the wiring from the AirCycler®
g2 to the air handler. The fan wire (G) must be interrupted by the AirCycler® g2. Some thermostats do not require a
common (C) connection. The AirCycler® g2 requires this for power, which must be wired to the furnace.

DAMPER LOCATION
The fresh air damper can be located anywhere in the inlet duct. Minimize the length of the inlet duct to improve air
ow and improve system eciency. It is recommended that the damper be as close to the return air plenum and the
AirCycler® g2 controller as possible, and the inlet duct connect to the return plenum upstream of the system lter, and
down- stream of any duct mounted sensors.
DAMPER INSTALLATION
The damper may be installed in any position. It is recommended to install it with the motor at the12 o’clock position if
mounted horizontally. Air may ow through in either direction, although it is recommended to install with the crimped
end as the outlet. Use care to avoid distorting the damper housing and provide adequate support.
CHOOSE A FRESH AIR LOCATION
ASHRAE recommends that the fresh air intake be located at least 10 ft. from any source of pollutants, such as auto
exhaust, dryer exhaust, exhaust from any fuel-burning appliances, etc. Avoid installation near odor sources such as
garbage bins or barbecue grills. A minimum of 3 ft. above ground is recommended to avoiding ingress of leaf litter,
grass clippings, etc. Do not use a crawl space, basement, or attic as a source of intake air. Always be sure to comply with
local building codes and requirements regarding fresh air inlets.

The AirCycler® g2 controller can be installed near the thermostat or out of view on/near the air handler unit. See the
wiring diagram on page 4.
Warning: Before installing the AirCycler®, turn o all power to the furnace. There may be more than one power to disconnect.
Electrical shock can cause injury or death.

1.0 THEORY OF OPERATION
No need for additional ventilation forced by AirCycler® g2.
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 eciency is drastically improved.
