• Cleaning: Wipe the thermostat's exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the device.
• Avoid Obstructions: Ensure that the thermostat's ventilation slots are not blocked by furniture or curtains, as this can affect temperature sensing accuracy.

7. Troubleshooting

If you encounter issues with your thermostat, try the following steps:

• No Display/No Power: Check the main power supply at your circuit breaker. Ensure the thermostat is correctly seated on its base plate and all wiring connections are secure.
• Incorrect Temperature Reading: Verify that the thermostat is not exposed to direct heat sources (e.g., sunlight, lamps) or cold drafts. Ensure proper air circulation around the unit.
• Heating Not Activating: Check your programmed schedule to ensure the thermostat is set to a heating period and the desired temperature is above the current room temperature. Verify the heating system itself is operational.
• Programming Errors: Refer to the operating instructions in Section 5 and the full manual for detailed programming steps. If necessary, reset the thermostat to factory settings (consult the full manual for this procedure).
