Troubleshooting | AirCycler® FRV/VS
Does the device have power?
You can determine that device is powered if the LCD display is illuminated.
If it is not illuminated, check the common wire connection. C must be connected to C on the furnace.
Why is my AirCycler® running constantly?
Check your thermostat. If the air handler is running when it shouldn't, first determine what state the AirCycler® is in. If the AirCycler® is telling you that it sees an input from the thermostat, make sure the FAN switch is set to AUTO and not ON and that it is not calling for heating or cooling.
How do I test my AirCycler®?
Trained technicians use Test Mode to verify or demonstrate the control operation. The test mode will display fan activity in seconds rather than minutes. To activate Test Mode follow these steps:
- Press thet Mode button.
- Press the Mode button a second time and hold for 6 seconds.
- To exit test mode and return to Operating Mode, turn the AirCycler® off.
- Hold the Mode button for two seconds, and then press Mode again to turn the AirCycler on.
As a safeguard, the AirCycler® will automatically exit Test Mode after 10 minutes.
