APPENDIX A

TROUBLESHOOTING

Problem: No power to AirCycler® g2

Check common wire connection. "C" must be connected to "C" on the furnace.

Problem: EXH icon is flashing

If the EXH icon is flashing it is indicating that the FanConnect™ switch has been on for more than four hours or has lost

connection with the AirCycler® g2 controller.

Problem: Furnace fan is running constantly

Make sure the thermostat FAN switch is set to AUTO and not ON

Problem: Central fan does not shut off when AirCycler® g2 is removed from base (when thermostat fan switch is on)

Check wiring - "G" wire from thermostat should be wired to "Gt" on AirCycler® g2. "Gf" on AirCycler® g2 should be

connected to "G" on furnace.

Problem: Blank Display on the AirCycler® g2

Confirm:

1. The furnace has power

2. The thermostat is operational

3. The furnace will call for heat from the thermostat

4. The fan operates with a fan only signal from the thermostat

5. The furnace is providing 24 VAC to the AirCycler® g2

6. Verify wiring conforms to wiring diagram

7. Make sure cover is firmly seated on the base

Problem: AirCycler® g2 turns furnace fan on and off, but the motorized damper does not cycle.

Confirm:

1. The AirCycler® g2 is providing a 24 VAC signal to the motorized damper

2. The 24 VAC motorized damper is operational by powering directly with a 24 VAC signal

3. There is continuity in the wiring between the damper and the AirCycler® g2

4. Confirm damper power switch is in up or automatic position

Problem: A/C turns on during fan cycling calls

Confirm:

1. Wiring conforms to wiring diagram

2. The G wire is properly connected

3. The G wire needs to be interrupted by the AirCycler® g2

4. Do not run the G wire in parallel

Problem: The AirCycler® G2 does not detect the optional FanConnect™ switch

Confirm:

1. Verify the FanConnect™ has power and is in the OFF position

TIPS

1. Make sure the FanConnect™ switch is in the OFF position when the AirCycler® g2 is first powered on.

2. Setup is easier to start without the battery installed. The battery is only used for the real time clock. If you

are not using the operating hours setting, the battery is not needed.

3. To set the AirCycler® g2 to "Inverse Slave Mode" - run the exhaust fan whenever the central fan is not running - enter

Calculated Flow setup. Set Measured Supply Air Flow, Measured Exhaust Air Flow, and Required Constant Airflow to the

same levels. For example, set all to 60 CFM.
