- Enter your Wi-Fi password in the app and follow the prompts to complete the connection.
4. Operation
This section details how to use your VEYFIY WiTH3-WIFI thermostat for effective heating control.
4.1 Manual Temperature Adjustment

- Rotary Knob: Turn the rotary knob clockwise to increase the set temperature and counter-clockwise to decrease it. The new set temperature will be displayed prominently.
- Temperature Units: The thermostat supports both Celsius (°C) and Fahrenheit (°F). You can switch between these units in the settings menu or via the Tuya Smart app.
4.2 Programmable Heating Schedules
Utilize the programmable schedule feature to optimize comfort and energy savings.
- Access Schedule Settings: This feature is primarily managed through the Tuya Smart app. Open the app and navigate to your thermostat's settings.
- Create/Edit Schedules: Set different temperature points for various times of the day and days of the week (e.g., wake-up, away, home, sleep).
- Activate Schedule: Ensure the thermostat is in "Program Mode" (indicated on the display or in the app) for the schedule to take effect.
4.3 Remote Control via Tuya Smart App
The Tuya Smart app provides comprehensive control over your thermostat from anywhere with an internet connection.
- Remote Adjustment: Change the set temperature, switch modes, and adjust settings from your smartphone.
- Real-Time Monitoring: View current room temperature, humidity, and weather data directly in the app.
- Advanced Features: Access features like child lock, open window detection, and calibration settings.
4.4 Antifreeze Function
The antifreeze function helps protect your pipes from freezing during cold weather when the heating system is off or set to a very low temperature. This feature automatically activates the boiler if the room temperature drops below a preset threshold (e.g., 5°C / 41°F).
- This function is typically enabled by default. Check the app or thermostat settings to confirm its status.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your thermostat.
- Cleaning: Wipe the thermostat and receiver units with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse in water.
