This guide is for homeowners and installers using the Heatmiser Thermal Actuator TA230 to control underfloor heating systems. The TA230 provides precise temperature control for individual zones, improving comfort and efficiency. However, proper wiring and integration with a compatible wiring center are essential for optimal performance.

The Heatmiser TA230 operates on a 230VAC power supply.
The stroke length is 3.5mm +/- 0.5mm.
The TA230 uses an M30 x 1.5 threaded ring nut connection.
The TA230 is installed on the manifold, directly onto the valves controlling the underfloor heating zones.
If you are competent with electrical wiring, you can replace the actuator. Ensure power is switched off before commencing. If unsure, consult a qualified professional.
Normally closed means that the valve is closed when the actuator is not powered. When the thermostat calls for heat, the actuator receives power and opens the valve.
The IP rating is IP54, providing protection against dust and water spray.
The Heatmiser UH4 and UH8 wiring centers are recommended.
Check the wiring connections to the wiring center and the thermostat. Ensure the power supply is working and that the thermostat is correctly configured. Replace the actuator if necessary.
Verify that the valve is opening. Check the water flow through the manifold and ensure the underfloor heating system is operational. Check for airlocks in the system.
Check the valve for obstructions. If the noise persists, the actuator may be faulty and need replacing.
The TA230 is compatible with underfloor heating systems that use manifolds with M30 x 1.5 connections and are designed for 230VAC operation. It is best used with Heatmiser's UH4 and UH8 wiring centers.
