Uniform heating

In a standard underfloor heating system, hydronic balancing is a very difficult and laborious process. The THB230 / THB24 has two temperature sensors that are connected between the Auto Balancing Actuator and the emitter flow & return pipes or the inlet and outlet of the manifold.

FEATURES:

  • Normally Closed
  • Short response time - 30 seconds
  • High precision motor
  • Constant temperature - no more too hot or too cold rooms
  • Modulates the valves opening to maintain an optimal ΔT:
    * 7°C for temperatures ≥ 30°C
    * 4°C for temperatures < 30°C
  • 2-piece pipe sensors will measure flow and return temperatures
  • Low power consumption - less than 0,5 W
  • Available in 230 V and 24 V version
  • 5 year warranty

How does it work?
To correctly balance the flow of heated water through the UFH circuit the flow rate needs to be regulated: too much flow will lower the ∆T below 7°C and the circuit will ’’heat up too fast’’, too little flow will increase the ∆T above 7°C and the circuit will ‘’heat up too slowly’’.

The ABA is the answer for ‘’getting effective control of UFH circuit’’. ABA will constantly measure the ∆T via the two temperature sensors and adjust the valve position by closing or opening its slightly. All to maintain constant 7°C temperature differential (between the emitter flow and return pipes) and make your UFH circuit really effective - economy, convenient.
