TacoSys Pro

The TacoSys Pro heating circuit manifolds from Taconova ensure the perfect distribution of heat throughout the entire house.


The TacoSys Pro is a next-generation heating circuit manifold, which now comes with two new components. Firstly, the TopMeter Plus balancing valve, which is positioned in the supply and allows reproducible adjustment of the flow control at the stop limit. The last setting can thus be restored any time in compliance with DIN-EN 1264-4. Secondly, the TacoDrive valve drive unit, in which case the actuator has been integrated directly in the valve. The actuator is extremely compact and has a reversible first-open function, with the force of the expansion element acting directly on the valve.
Different valve positions result in different flow volumes. They thus guarantee individual regulation of the room temperature, precisely tailored to the requirements of your customers.
The TacoVent Vent air vent ensures fully automatic ventilation of supply and return, thus enhancing operat­ing safety and user convenience.
The underfloor heating circuit manifolds are supplied fully pre-assembled and ready-for-connection.
The high-quality stainless steel TacoSys Pro manifold can be supplied with between two and twelve heating circuits.
It fulfills all requirements with respect to performance, energy efficiency, reliability, durability and comfort.


  • Balancing with TopMeter Plus in the supply circuit
  • Directly integrated TacoDrive valve drive unit
  • TacoDrive offers high protection class (IP54)
  • Integrated valve position indicator
  • Compliance with DIN-EN 1264-4 standard
