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.
