INTRODUCTION
If the AirCycler® g1 was installed in your home as a ventilation controller, turning off 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 efficient 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 flow to the home without compromising its efficiency.
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 filtered by the return plenum filter 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.
