4. Maintenance
To ensure optimal performance and longevity of your Wenzhi Wifi Heating Thermostat, follow these general maintenance guidelines:
- Cleaning: Gently wipe the screen and body with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or chemical sprays, as these can damage the surface and internal components.
- Avoid Physical Damage: Protect the thermostat from impacts, drops, and excessive force. The acrylic mirror, while durable, can be scratched or cracked under harsh conditions.
- Environmental Conditions: Ensure the thermostat is installed in an environment within its specified ambient humidity and temperature ranges to prevent malfunction.
- Power Supply: Ensure a stable power supply within the specified voltage range (95V-240V) to prevent electrical issues.
5. Troubleshooting
If you encounter any issues with your Wenzhi Wifi Heating Thermostat, consider the following:
- No Power/Display: Check the power supply and ensure all wiring connections are secure according to the installation diagram. Verify that the circuit breaker is not tripped.
- Incorrect Temperature Reading: Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources that could affect its internal sensor. For the WZ-006-GB model, verify the external sensor is correctly installed and positioned.
- Wi-Fi Connectivity Issues: Ensure your home Wi-Fi network is active and the thermostat is within range. Try restarting your router and the thermostat. The new version supports Bluetooth + Wi-Fi for faster network configuration, which might help with initial setup.
- App Control Not Working: Verify that the Tuya/Smart Life app is updated to the latest version and the thermostat is properly paired. Check your internet connection.
- Heating System Not Responding: Confirm that the thermostat is correctly wired to your heating system (water heating, electric floor heating, or gas boiler) as per the specific model's wiring diagram. Check the heating system itself for any faults.
- Heating by Sensor vs. Room Temperature: The WZ-006-GB model (electric heating) includes an external sensor, allowing for more precise floor temperature control. GA and GC models primarily rely on the internal room temperature sensor.
If troubleshooting steps do not resolve the issue, please contact after-sales service for assistance. Do not attempt to repair the device yourself.
