Thermal Actuator for Underfloor Heating Systems (NC, 230V)
This high-performance thermal actuator is designed for precise and reliable control of water-based underfloor heating manifolds. Engineered for long-term durability and stable operation, it ensures efficient zone control and consistent indoor comfort.
With a Normally Closed (NC) operating principle, the actuator opens only when powered, making it a safe and energy-efficient solution for modern heating systems. Its robust construction, high actuation force, and IP54 protection make it suitable for both residential and commercial installations.
Thanks to the standard M30×1.5 connection, installation is quick and fully compatible with most European heating manifolds.
