More info



Two temperature sensors are connected between the Auto Balancing Actuator and the emitter flow & return pipes or the inlet and outlet of the manifold. The Auto Balancing Actuator will measure the temperature sensors and adjust the valve position to maintain a constant 7°C temperature differential between the emitter flow and return pipes.

  • Very Low Power, less than 0.5W
  • Fast actuator opening and closing times typically 30 seconds
  • Performs the function of both the thermal actuator & the flow regulator, resulting in two functions in one unit
  • Quick to install - Fit & Forget
  • Reduced fuel bills, correctly temperature balanced rooms
  • Constant temperature, no more too hot or too cold rooms
  • Less user complaints, due to product installed correctly
  • Compatible with 16mm pipe


How the actuator worksHow It Works

The actuator has two remote sensors which are placed on the flow and return pipes from the manifold (16mm pipe only). These sensors are constantly monitored and the actuator will adjust the flow rate to maintain a Delta T of 7°C for the UFH circuit. With a very low power consumption of just 0.5W the Auto Balancing Actuator uses much less energy than conventional thermal actuators that typically use 2-3W or more. With a very fast opening and closing action of typically 30 seconds it is also much faster than conventional thermal actuators that can take 3 minutes or more to open or close.

The Auto Balancing Actuator behaves just like a normal thermal actuator however, rather than use a thermal wax element that expands and contracts to control the ON/OFF of the manifold valve it uses a high precision motor to move the valve pin very precisely. Together with knowing the flow and return temperatures the valve can now achieve an automatic balance for the UFH circuit.
