2.Manual valve adjustment method:

  • Turn the valve clockwise to close and counterclockwise to open.
  • Turn slowly when adjusting to avoid damage caused by excessive force.
  • It is recommended to fully open it first, then gradually turn it down after the room temperature rises to find a comfortable temperature.

3.Thermostatic valve adjustment method:

  • Set the target temperature (usually 1-5, the larger the number, the higher the temperature).
  • The valve automatically adjusts the water flow based on room temperature, eliminating the need for frequent manual operations.
