Thermostatic head with remote sensor and 2 m capillary, setting 10-50°C, t=10 s T100R-AA

Operates Without Power, Yet with Precision

The thermostat head controls room temperature without requiring external power – temperature changes cause the liquid inside the sensor to expand or contract, automatically opening or closing the valve. The liquid-filled sensor, connected to the head via a 2-meter capillary, allows installation in the most representative location for temperature measurement – e.g., on a wall, far from the radiator or other heat sources. This is particularly useful when the radiator is concealed or located under a window.

Installation and Maintenance Without Draining the System

Features a built-in protective sleeve (pozzetto) for immersing the sensor into the pipe – meaning there is no need to drain water from the system when replacing the head. Replacement is simple and quick, even with a fully pressurized installation. Compatible with all radiator valves featuring an M30 x 1.5 connection and a lockshield length of 11.5 mm – ensuring no compatibility issues during replacement or modernization.

Freeze Protection and Operational Stability

The adjustable range from 10 to 50 °C enables maintenance of a minimum room temperature even at low settings – ideal for apartments left unoccupied for extended periods. A 10-second response time offers a balance between speed and stability: it does not react to momentary temperature fluctuations (e.g., opening a door) but effectively maintains the set value. The white color (RAL 9016) blends seamlessly with standard radiators and surrounding interiors.

5-Year Warranty – A Safe Choice

The manufacturer offers a 5-year warranty from the date of production, indicating that the design is engineered for long-term reliability. All contact components (sleeve, sensor cover) are made of nickel-plated brass, while the housing is constructed from aging-resistant white plastic. There is no remote control function or anti-theft lock – this is a simple, mechanical component that operates exactly as it did decades ago: without batteries, without signals, and without electronic failures.
