7. Maintenance

Regular maintenance ensures optimal performance and longevity of your thermostat.

• Cleaning: Gently wipe the thermostat's screen and casing with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the device.

If you encounter issues with your Zerodis Smart Thermostat, refer to the following common problems and solutions:

• Thermostat not powering on:
  • Check the circuit breaker for your HVAC system to ensure power is on.
  • Verify all wiring connections are secure.
• Incorrect temperature readings:
  • Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources.
  • Clean any dust or debris from the thermostat's sensors (if accessible).
