Heatmiser TA230 Underfloor Heating Thermal Actuator

The Heatmiser TA230 Underfloor Heating Thermal Actuator 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.

Installation

Please Note: This is a brief guide. Always refer to the full installation manual for comprehensive instructions.

1. Plan Your Layout:

• Divide the floor into a series of rectangles. Use these measurements to calculate the number and sizes of mats needed, excluding permanent or static fixtures from your calculations.

2. Prepare the Subfloor:

• For screed over concrete floors, lay insulation boards to minimize heat loss and ensure quicker warm-up times.

3. Lay the Heating Mat:

• Start with the first run of the mat. Cut the mat (leaving the cable intact) at the end of each run, turn it 90° or 180°, and continue laying.
• Once the area is covered, adjust the mat so that the loops are evenly spaced.
• Secure the mat to the subfloor using the special tape provided.

4. Electrical Connections:

• Install an RCD fused spur to power the thermostatic controller/programmer and the mat system.
• Lay the temperature probe from the timer-thermostat onto the floor, position it equidistant between two cable loops, and secure it to the surface.
• Position the unheated power supply cable from the end of the mat system near the thermostat.
• Make all necessary connections to the power supply. Run the heaters for no more than 10 minutes to ensure they are heating up properly.

5. Finish the Flooring:

• Option 1: Apply a thin, self-levelling screed over the mat and allow it to dry completely before laying tiles.
• Option 2: Directly trowel flexible tile adhesive over the mat and lay the floor tiles.
• After grouting, let the tile adhesive cure fully before switching on the system.
