4. Operation

4.1 Operating Modes

The thermostat supports two primary operating modes:

• Automatic Mode: Follows the programmed weekly schedule.
• Manual Mode: Maintains a constant temperature set by the user, overriding the schedule.

4.2 Weekly Programming

You can customize your heating schedule for optimal comfort and energy saving.

• The thermostat supports 5+2 (weekdays + weekend), 6+1 (weekdays + one weekend day), or 7-day programming.
• Typically, there are 6 time periods for weekdays and 2 for rest days, each with its own temperature setting.
• Refer to the app or the thermostat's on-screen menu for detailed programming instructions.

4.3 Temperature Control Settings

• Temperature Hysteresis: Adjustable from 0.5°C to 10°C. This setting determines the temperature differential before the heating system reactivates.
• Minimum Temperature Setting: The lowest settable temperature is 0.5°C.
• Temperature Calibration: Adjust the temperature reading from -9.9°C to 9.9°C to match an external reference thermometer if needed.

4.4 Voice Control

Integrate your thermostat with Amazon Alexa or Google Home for convenient voice commands.

1. Ensure your thermostat is successfully paired with the Tuya Smart or Smart Life app.
2. Open your Alexa or Google Home app.

Activate the child lock feature to prevent accidental changes to the thermostat settings by pressing and holding specific buttons (refer to your device's specific button combination) or through the mobile app.

4.6 Anti-freeze Function

The thermostat includes an automatic anti-freeze function. If the ambient temperature drops to a critically low level (typically around 5°C, adjustable in advanced settings), the thermostat will briefly activate the heating system to prevent water pipes from freezing and bursting.

5. Maintenance

• Cleaning: Wipe the thermostat's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Battery Replacement: Replace the batteries in the thermostat unit when the low battery indicator appears on the display. Use three new 1.5V AA batteries.
• Firmware Updates: Periodically check the Tuya/Smart Life app for available firmware updates to ensure optimal performance and access to new features.

6. Troubleshooting

• Thermostat not powering on: Check battery installation and ensure batteries are new. For the receiver, verify AC power connection.
• No WiFi connection: Ensure your router is broadcasting a 2.4GHz signal. Restart your router and the thermostat. Re-attempt the pairing process in the app.
• Inaccurate temperature reading: Use the temperature calibration feature in the settings to adjust the reading if necessary. Ensure the thermostat is not exposed to direct heat sources or drafts.
• Heating not activating: Check the operating mode (ensure it's not in 'Off' or 'Manual' with a low setpoint). Verify the receiver unit is powered and correctly wired to the boiler.
• Voice control not working: Confirm the Tuya/Smart Life skill is enabled and linked in your Alexa/Google Home app. Ensure the thermostat is online in the Tuya/Smart Life app.
