## Long description

The SCHLOSSER Diamant Invest thermostatic radiator valve head in white is a compact control unit designed to fit radiator valve bodies with an M30 x 1.5mm connection.

How to use
Mount the thermostatic head by screwing it onto a compatible radiator valve body with the correct thread. Align and tighten by hand, then use the numbered scale to set the desired room temperature. Turn the head to increase or decrease the flow through the radiator; the mechanical thermostat modulates valve opening based on the selected setpoint.

For optimal performance, ensure the thermostatic head is installed on a valve body designed for M30 x 1.5mm connections and positioned where airflow and direct sunlight do not affect temperature sensing. Regularly check for free movement of the actuator pin and avoid covering the radiator with large furniture or drapes that could interfere with accurate room temperature measurement.
