- Sensor Care: Ensure the external floor sensor (if installed) is free from obstructions and debris to ensure accurate readings.
- No User-Serviceable Parts: Do not attempt to open or repair the device yourself. Refer to qualified service personnel for any repairs.
6. Troubleshooting
- Display Not Working: Check the main power supply. Ensure the controller is properly installed and connected.
- Incorrect Temperature Reading: Verify that the sensor is correctly connected and not damaged. Ensure the sensor is placed appropriately for accurate measurement.
- Heating Not Activating: Check the set temperature to ensure it is above the current room temperature. Verify the operating mode and schedule. Ensure the heating element is functioning correctly.
- Programming Issues: Refer to the detailed programming instructions in the full user manual. Ensure all steps are followed correctly.
