6. App and Wi-Fi Setup

To unlock the full potential of your AVATTO Smart Thermostat, connect it to your home Wi-Fi network and the compatible mobile application.

1. Download the App: Search for "Smart Life" or "Tuya Smart" in your mobile app store (iOS or Android) and download the application.
2. Register/Login: Open the app and register for a new account or log in if you already have one.
3. Add Device: In the app, tap the "+" icon (usually in the top right corner) to add a new device. Select "Thermostat" or "Heater" from the device list.
4. Pairing Mode: On the thermostat, press and hold the Wi-Fi icon button (or a similar pairing button) until the Wi-Fi indicator light starts blinking rapidly. This indicates it's in pairing mode.
5. Connect to Wi-Fi: Follow the on-screen instructions in the app. You will need to enter your home Wi-Fi network name (SSID) and password. Ensure your phone is connected to a 2.4GHz Wi-Fi network (5GHz networks are generally not supported by smart home devices).

7. Operating Modes

The AVATTO WT410-BH-3A-W thermostat supports four main operating modes to suit your heating needs:

• Manual Mode: In this mode, the thermostat maintains a constant temperature set by the user until manually changed. It overrides any programmed schedules.
• Programming Mode: The thermostat follows the pre-set weekly schedule, automatically adjusting the temperature at specified times.
• Temporary Programming Mode: While in Programming Mode, you can temporarily adjust the temperature. The thermostat will maintain this new temperature until the next scheduled program change, then revert to the schedule.
• Absence Mode (Holiday Mode): Designed for extended periods away from home. You can set a lower, energy-saving temperature for a specified duration, and the thermostat will automatically resume normal operation afterward.

Switch between modes using the dedicated mode button on the thermostat or through the mobile application.

8. Weekly Programming

The thermostat allows for advanced weekly programming, enabling you to set different temperatures for specific time periods throughout the week. This helps optimize comfort and energy efficiency.

You can set up to 6 time periods for weekdays (Monday-Friday) and 2 time periods for weekends (Saturday-Sunday).

1. Access Programming: Press and hold the "M" (Mode) button or navigate to the "Schedule" section in the mobile app.
2. Set Weekday Schedule: For Monday to Friday, define up to 6 time periods (e.g., Wake, Leave, Return, Sleep) and their corresponding desired temperatures.
3. Set Weekend Schedule: For Saturday and Sunday, define up to 2 time periods and their desired temperatures.
4. Save Settings: Confirm and save your programming. The thermostat will now follow this schedule when in Programming Mode.

The thermostat offers high precision with temperature settings, accurate to 0.5°C, and displays temperature with 0.1°C precision. An adjustable hysteresis function (0.5°C to 10°C) allows fine-tuning of temperature deviation.

9. Maintenance

The AVATTO WT410-BH-3A-W Smart Thermostat requires minimal maintenance to ensure long-term performance.
