Menu Structure and Mode Selection:
From the main interface, short press the Mode button to enter the mode switching interface. Use the Plus (+) or Minus (-) buttons to toggle between available modes, then press the Mode button to confirm your selection.
Available Modes:
- Heating Mode: Controls a connected heating device. Use the Plus/Minus buttons to adjust the target temperature.
- Cooling Mode: Controls a connected cooling device. Use the Plus/Minus buttons to adjust the target temperature.
- Socket Mode: Allows manual toggling of the output status (ON/OFF) and setting a delay time.
- Cycle Timer Mode: The socket cycles between ON and OFF states at regular, user-defined intervals. Set the ON time duration first, then the OFF time duration using the Plus/Minus buttons and confirming with the Mode button.
- Programming Mode (Prog. Heating/Prog. Cooling): Allows viewing of weekly programming settings directly on the device. Specific programming schedules (e.g., different temperatures for different times of day/week) can only be set and managed via the Smart Life/AVATTO app.
Setting Menu:
From the mode switching interface, navigate to "Setting" and press the Mode button to access various device settings:
- Screen: Adjust screen brightness (High/Middle/Low) and screen timeout (15s/30s/60s/120s).
- Child Lock: Enable or disable child lock for physical buttons.
- Network: Manage network settings and initiate pairing mode.
- Advanced: Access advanced temperature control parameters.
- About: View device information.
Advanced Temperature Settings:
- Temperature Unit: Switch between Celsius (°C) and Fahrenheit (°F).
- Temperature Calibration: Adjust the displayed temperature to match an external reference, if needed. Range: -15~15°C (-15~15°F).
- Temperature Difference (Hysteresis): Sets the temperature differential required for switching the device on and off. For example, if set to 1.0°C and the target is 20.0°C in heating mode, the device will heat when the room temperature drops to 19.0°C and stop at 20.0°C. In cooling mode, it will cool at 21.0°C and stop at 20.0°C. Range: 0.1~10°C (0.2~30°F).
- Cooling Delay: Effective only in cooling mode. If the setpoint temperature is reached, the device will wait for a specified period before starting cooling to protect the compressor. This prevents rapid cycling of the cooling unit. Range: 1~10 minutes.
- Frost Protection: Enable/Disable a feature to prevent temperatures from dropping below a certain threshold (e.g., 5°C) to protect pipes or plants.
- High Temp. Alert: Set a maximum temperature threshold. If exceeded, an alarm will trigger. Range: -30~110°C (-22~230°F).
- Low Temp. Alert: Set a minimum temperature threshold. If the temperature drops below this, an alarm will trigger. Range: -30~110°C (-22~230°F).
- Factory Reset: Resets all settings to their default values.

7. Maintenance
To ensure optimal performance and longevity of your AVATTO Tuya WiFi Thermostat Socket, follow these simple maintenance guidelines:
- Cleaning: Wipe the device with a dry, soft cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface or internal components.
- Storage: If storing the device for an extended period, ensure it is unplugged and kept in a cool, dry place away from direct sunlight and extreme temperatures.
- Sensor Care: Handle the temperature sensors carefully. Avoid bending or kinking the sensor cables excessively. Ensure the sensor tip is clean and free from debris for accurate readings.
8. Troubleshooting
If you encounter issues with your AVATTO Tuya WiFi Thermostat Socket, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not pairing with app | Incorrect Wi-Fi band, Bluetooth off, device not in pairing mode, incorrect Wi-Fi password. | Ensure your phone's Wi-Fi is 2.4GHz and Bluetooth is on. Put the thermostat into pairing mode as described in Section 4. Double-check your Wi-Fi password. |
| Inaccurate temperature readings | Sensor placement, sensor damage, calibration needed. | Ensure the sensor is placed correctly and not exposed to direct heat/cold sources. Check the sensor for visible damage. Use the temperature calibration feature in the settings menu to adjust. |
| Device offline in app | Wi-Fi signal loss, router issues, device unplugged. | Check your Wi-Fi router and signal strength. Ensure the thermostat is plugged in and powered on. Re-pair the device if necessary. |
| Connected appliance not turning ON/OFF | Incorrect mode, appliance not working, thermostat fault. | Verify the thermostat is in the correct mode (Heating/Cooling/Socket). Check if the appliance itself is working. Ensure the thermostat is receiving power. |
| High/Low Temperature Alarm not working | Alarm thresholds not set, alarm disabled. | Check the High/Low Temp. Alert settings in the Advanced Settings menu via the device or app. Ensure the alarm is enabled and thresholds are appropriate. |
9. User Tips
- Optimal Sensor Placement: For the most accurate temperature readings, place the external temperature sensor in the area where you want to maintain the temperature, away from direct drafts, sunlight, or heat sources.
- Leverage Programming Mode: Utilize the weekly programming feature via the Smart Life/AVATTO app to set custom temperature schedules. This can significantly improve comfort and energy efficiency by automatically adjusting temperatures based on your daily routine.
- Check Wi-Fi Band: During initial setup, always confirm your router is broadcasting a 2.4GHz Wi-Fi signal and your phone is connected to it. This is a common point of failure for smart device pairing.
- Child Lock: If you have children, consider enabling the child lock feature to prevent accidental changes to the thermostat settings.
