INTRODUCTION
If the AirCycler® g1 was installed in your home as a ventilation controller, turning o or otherwise disabling the
controller could result in under ventilating your home and could adversely impact indoor air quality.
In the past, homes depended on natural leaks for ventilation. Today, energy ecient homes are built to reduce natural
ventilation and leaks. Inadequate ventilation can cause indoor air pollutants to rise to harmful levels. Indoor air quality
is typically 5 to 10 times more polluted than outside air. Controlled ventilation systems like the AirCycler® g1 provide
adequate air ow to the home without compromising its eciency.
The AirCycler® g1 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® g1 controller opens a 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. If there are not enough heating or cooling calls to meet ventilation requirements for the hour the
AirCycler® g1 will turn on the furnace fan and open the motorized damper until requirements have been met.
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® g1 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®
g1 to the air handler. The fan wire (G) must be interrupted by the AirCycler® g1. Some thermostats do not require a
common (C) connection. The AirCycler® g1 requires this for power, which must be wired to the furnace.
BATTERY (MODEL CR1220)
The AirCycler® g1 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.
RECORD ALL SETTINGS ON THE INSTALL STICKER PROVIDED. LIMITED
WARRANTY WILL BE VOID IF THE STICKER IS NOT PRESENT.

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 eciency. It is recommended that the damper be as close to the return air plenum and the
AirCycler® g1 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 the 12 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.

1.0 INSTALLATION & CONFIGURATION INSTRUCTIONS
1.1 AIRCYCLER® G1 CONTROLLER LOCATION
The AirCycler® g1 controller can be installed near the thermostat or out of view on/near the air handler unit.
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.
1.2 CONFIGURING THE AIRCYCLER G1®
On power up, all icons will be illuminated for 3 seconds.
There are two set up methods: Calculated Flow and Calculated Time. If you know the amount of fresh air coming into the
air handler as well as ow required by code you can use Calculated Flow to meet requirements. If you prefer to congure
the amount of time you want fresh air to enter the home per hour, use Calculated Time.
To set up the AirCycler® g1 based on Calculated Flow press and hold the UP arrow for 10 seconds.
To set up the AirCycler® g1 based on Calculated Time press and hold the DOWN arrow for 10 seconds.
OPERATING MODE DISPLAY
When the AirCycler® is in Normal Operation, the display will show
the percentage of ventilation complete for the current hour.
If the outside fresh air damper is open the OA icon will show.
If the thermostat is calling for heat or cool, the FAN icon will be
illuminated without the ON icon.
If the central fan is on, the FAN and ON icons will show. The
ON icon is only illuminated when the AirCycler® g1 has
forced the central fan on.
Pressing the MODE button at any time during normal
operation will go to setting the current time of day.
