The Heatmiser thermal actuator TA230 is a reliable and efficient 2 wire thermal actuator specifically designed to control individual valves on a manifold system. When prompted by a room thermostat, the thermal actuator opens the valves, allowing for precise control of the heating in each room or zone.

To ensure seamless integration into your underfloor heating system, the Heatmiser thermal actuator is typically wired into an underfloor heating wiring centre, such as the Heatmiser UH4 or UH8. This enables centralized control and synchronization of the thermal actuators throughout the system, ensuring optimal performance and energy efficiency.

For convenient installation, the thermal actuator comes complete with a threaded ring nut M30 x 1.5. Prior to fitting the actuator, the threaded ring nut is securely screwed onto the manifold, providing a sturdy base for attaching the actuator. The actuator easily clips onto the threaded ring nut, streamlining the installation process and saving valuable time.

The Heatmiser thermal actuator operates on a 230v power supply, ensuring consistent and reliable performance. With its 2 wire normally closed configuration, the actuator efficiently controls the flow of heating water, allowing for precise temperature regulation and comfort control in each room or zone.

The stroke length of the thermal actuator is 3.5mm +/- 0.5, providing the necessary movement to open and close the valves with accuracy and precision. This ensures smooth and responsive operation, allowing for precise adjustment of the heating flow in response to the room thermostat signals.

Choose the Heatmiser thermal actuator - 2 Wire for your underfloor heating system and experience efficient, reliable, and customizable control of your heating zones. With its robust construction, convenient installation features, and compatibility with underfloor heating wiring centres, this thermal actuator is a valuable addition to any heating system.
