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.
How does it work?
The AirCycler® g2-k System is integrated with the home’s HVAC system. When the home’s furnace fan is turned on
by the thermostat to provide heating or cooling, the AirCycler® g2 controller opens the motorized damper to let in
a measured amount of fresh air. The fresh air is ltered by the return plenum lter and is then distributed uniformly
throughout the home through the existing ductwork. Once the ventilation requirements are met, the damper is closed
to prevent over-ventilation.
By running the ventilation system at the same time as the home’s regular heating and cooling cycles, the AirCycler®
g2-k System saves on additional utility costs.
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.

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.
AIRCYCLER® g2 CONTROLLER LOCATION
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.
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. Upon system start up
be sure to set damper power switch to UP or AUTOMATIC position.
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.
BATTERY (MODEL CR1220)
The AirCycler® g2 is equipped with a real time battery backed-up clock for use with the Operation Hours setting ONLY.
If not setting the hours of operation, the included battery is not required. All other settings are saved in nonvolatile
memory.

FANCONNECT™ SWITCH WIRING (OPTIONAL)
INTRODUCTION
Power for the g2 controller, damper and FanConnect™
switch comes from the 24VAC supply in the furnace.
The damper draws only 35mA during the 15 seconds it
takes to open or close.
The relay in the FanConnect™ switch draws 100mA when
the controller is activating the bath fan.
All can be wired with standard 18-22awg 600V thermostat
wire.

WIRING
The switch requires an always hot
110VAC feed. (Black wire & White
neutral wire)
The Blue 110VAC switch leg (load)
powers the light circuit. It is a simple
mechanical contact within the toggle
switch. It can handle up to 450 Watts.
The Red 110VAC switch leg (load)
powers the fan. This is also a mechanical
contact within the internal relay. It can
handle up to 150 Watts. Works ne with
DC fans.
INSIDE THE FANCONNECT™ SWITCH
Inside the FanConnect™ switch is a
24VAC relay to control the 110VAC bath
fan.
Anytime the light switch is turned on,
the fan circuit is energized supplying
power to the fan.
The AirCycler® g2 controller can:
• Read when the bath fan is on and
track that time.
• Turn fan on for a delay time after
bathroom is used.
• Turn fan on for a programmed
amount of time every hour to meet
ventilation requirements.

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
