The Heatmiser TA230 is a 230V, 2-wire thermal actuator designed for precise control of individual manifold circuit valves in underfloor heating systems. When connected to a room thermostat, it enables accurate regulation of heating zones by opening or closing valves as needed.
Featuring a compact design and a threaded ring nut (M30 x 1.5), the actuator ensures straightforward installation and compatibility with most standard manifolds. Its normally closed configuration prevents unwanted heat flow when inactive, enhancing energy efficiency.
