Precise heating control: with a rated stroke of 4.0 mm and a rated actuating force of 110 N, this thermal actuator enables very accurate control of the underfloor heating circuits. This allows a stable and comfortable room temperature to be maintained and helps to avoid overheating or underheating. Efficient and low maintenance: this actuator for underfloor heating uses reliable PTC heating technology. When heated, the paraffin expands and precisely presses on the valve core shaft. The unit includes an automatic reset function, operates almost silently and safely closes the valve in the event of a power failure for added protection. Easy, tool‑free installation: the actuator is designed for quick mounting and removal without additional tools, saving time during installation and maintenance. Thanks to the 360° valve adapter system and the practical 2‑wire connection, the device is compatible with common systems. High performance and comfort: advanced thermal actuation technology ensures even heat distribution across the entire room, avoiding cold spots and excessive heat zones. The precise temperature control not only increases living comfort but can also help reduce unnecessary consumption., Weight: 0.57099725858 Pounds, Manufacturer: Hipzeepo
