The Herz thermostat functions as a room temperature sensing and control unit.
It is suitable for the control of radiators installed in spaces that are difficult to access.
The sensor and adjustment component is mounted onto a wall at a location accessible to the air circulation. The change in the volume of liquid in the HERZ hydrosensor is transmitted through the capillary tube to the system of bellows located under the valve cover, which in turn actuates the radiator valve.
The system is supplied with an excess temperature safety device.
