Heatmiser 230v Thermal Actuator

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.

• 230V powered – Ensures consistent and reliable operation
• 2-wire normally closed configuration – Enhances energy efficiency by preventing heat leakage
• M30 x 1.5 threaded connection – Facilitates easy and secure attachment to manifold valves
• Stroke length: 3.5mm ± 0.5mm – Provides precise control over valve operation
• Opening time: 120–180 seconds – Allows for smooth and responsive adjustments to heating demands
• Power consumption: 2W – Offers energy-efficient performance
• IP54 protection rating – Suitable for various environments, ensuring durability
• Compact dimensions – Measures approximately 45 x 49.5 x 58 mm for space-constrained installations
• Visual operation indicator – Orange marker rises when the valve is open, providing clear status indication

Compatible with Heatmiser wiring centres such as the UH4 and UH8, the TA230 integrates seamlessly into underfloor heating systems, offering reliable and efficient zone control.
