5. Installation
The EZAIoT Smart Radiator Thermostat is designed for easy DIY installation. Follow these steps to replace your existing radiator valve:
- Prepare the Radiator: Turn off your heating system and allow the radiator to cool down.
- Remove Old Thermostat: Unscrew your existing thermostatic radiator valve head. No need to drain water from the radiator.
- Select Adapter: Identify the correct adapter from the included set that matches your radiator valve. The thermostat is compatible with most common radiator valves (e.g., M30 x 1.5).
- Install Adapter (if needed): If an adapter is required, screw it onto the radiator valve body.
- Attach Thermostat: Place the EZAIoT Smart Radiator Thermostat onto the adapter or directly onto the valve body and tighten it securely.
- Insert Batteries: Ensure the two AA batteries are correctly inserted into the thermostat.

7. Operating Instructions
7.1 Manual Control
You can adjust the temperature directly on the thermostat by rotating the main body. The OLED display will show the target temperature. The display can be rotated 0°/90°/180°/270° for optimal readability, especially in hard-to-reach areas.
7.2 App Control and Programming
Use the Tuya Smart Life app for comprehensive control:
- Set Temperature: Adjust the target temperature from anywhere.
- 7-Day Programming: Create custom heating schedules for each day of the week to match your routine and save energy.
- Holiday Mode: Set a specific temperature for an extended period when you are away.
- Child Lock: Activate the child lock feature to prevent unauthorized changes to settings on the device.
- Window Open Detection: The thermostat can detect sudden drops in temperature (e.g., when a window is opened) and temporarily pause heating to prevent energy waste.
- Frost Protection: Automatically maintains a minimum temperature to prevent pipes from freezing.
