Possible Causes

Sensor mode set to floor only, Internal sensor disabled, Remote sensor misconfigured, Installer settings changed

How to Fix / Troubleshooting

Safety first: No wiring changes required unless adding sensors.

Steps:

  • Enter the installer menu and check the sensor mode setting (e.g., Air, Floor, Air+Floor).
  • If you want room control, select Air or Air+Floor depending on your floor protection needs.
  • Ensure any remote or floor sensors are correctly connected and not generating error codes.
  • Save settings and verify that the thermostat now displays and controls based on room temperature.
