HINTS & TIPS
• Make sure the FanConnect switch is in the OFF position when the AirCycler® g2 controller is rst
powered on.
• 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 options, the battery is not needed.
TROUBLESHOOTING
No power?
Check common wire connection. “C” must be connected to “C” on the furnace.
EXH icon is ashing
If the EXH icon is ashing it is indicating that the FanConnect switch has been on for more than four
hours or has lost connection with the g2 controller.
My furnace fan runs constantly
Make sure the thermostat FAN switch is set to AUTO and not ON.
Fan does not shut o when AirCycler®g2 is removed from its base (when thermostat fan switch
is on) Check wiring - G wire from thermostat should be wired to Gt on AirCycler. Gf on AirCycler should
be connected to G on furnace.
FAQ
Will the AirCycler controller lose the settings if the power fails?
No, all settings are saved in non-volatile memory. No battery is needed.
The AirCycler® g2 has a small lithium battery to keep the clock running if you are not ventilating 24hrs
a day and are using that feature. It will maintain the time without power for at least 14 days.
Can I run multiple FanConnect switches o of one AirCycler® g2 controller?
No. For additional bathrooms use the SmartExhaust bath fan/light switch as an independent controller.
