Installation Instructions

1. Please pull out the insulating tab before use, and confirm that the device is turned on.
   
2. It is recommended to install the thermostat on the radiator valve interface within 5 minutes after the TRV starts up.
   
   1. The Thermostat supports both horizontal and vertical installation methods. However, the vertical installation method may result in inaccurate temperature readings caused by the built-in temperature sensor being close to the radiator.
      
      Note: In any of these methods, an external Aqara Temperature and Humidity Sensor is required to make temperature control more accurate.
   2. Align the thermostat interface nut with the radiator valve, and rotate the nut until it is tightened.
      
      Note: Installation of [M30*1.5 mm] valve interface is shown in the figure.
   3. Press the thermostat button 3 consecutive times to calibrate the valve. During calibration, the screen displays the [F12] symbol.
      
      Note: The valve must be calibrated, otherwise it may cause abnormal temperature control. Follow the above steps or click "More Settings" in the app to calibrate the valve.
   4. The [F12] symbol disappears in about 10 seconds, and the screen displays the currently set temperature, indicating the completion of installation.

Installation with Other Adapters:

RA Adapter

Connect the RA adapter with the valve, tighten the screw to complete the connection, then align the thermostat interface nut with the RA adapter, and rotate the interface nut until it is tightened.

RAV Adapter

Connect the RAV adapter with the valve, tighten the screw, insert the pushrod into the valve thimble to complete the connection, then align the thermostat interface nut with the RAV adapter, and rotate the interface nut until it is tightened.

RAVL Adapter

Connect the RAV adapter with the valve, tighten the screw, insert the pushrod into the valve thimble to complete the connection, then align the thermostat interface nut with the RAV adapter, and rotate the interface nut until it is tightened.
