Type Radiator thermostats
Operation Electromechanical
 
 

Herzcules is a robust, vandal-resistant radiator thermostat that is suitable for installation on Herz valves.

The mounting, dismounting and set-point control is only possible with special tools. It has a locked and concealed set point and features an automatic frost release.

Herzcules serves as a sensor and control element. The change in volume of the liquid contained in the hydrosensor actuates the valve spindle.

The thermostatic head features components that are visible from the outside:
• Fastening nut - metallic, nickel-plated, with two securing screws (2mm-Allen screws).
• Rib ring - can be rotated around the fastening nut.
• Locking sleeve with indentation.
• Handwheel with set value marks.

The thermostatic head is equipped with an adjustable dial with blue markings. Each section of the blue markings corresponds to a setting interval of minus 1K - the thicker the marking, the greater the decrease in temperature. The indicator is the raised display on the handwheel.

The Herzcules thermostat is maintenance free.
