Thermostat rapidly turns the system on and off (short cycling).

Safety: No high-voltage work is required.

• Secure mounting: Ensure the Lux wall plate is firmly attached to the wall and the thermostat snaps on securely without wobble.
• Adjust cycle rate: In the installer menu, reduce the cycle rate (CPH) to a lower value appropriate for your system.
• Redirect airflow: If a supply vent blows directly on the thermostat, adjust the vent louvers or partially close the vent.
• Relocate thermostat: For severe cases, have a professional move the thermostat to a more stable location.
