Innovative Control Technology / Connected Intelligence


On-demand ventilation even without a central building management system:
with decentralised control intelligence


Connected Intelligence offers an inexpensive and flexible automation solution for LTG air-water systems. The System permits on-demand and room-matched ventilation and air conditioning with or without a building management system (BMS). Inexpensive and easy to install, the units can be connected to form a network that is compatible with existing building automation solutions and open for many different sensor systems.

Innovative automation solution

  • Relocation of the control tasks for energy- efficient air conditioning on the local field level
  • Simple implementation of energy-efficient demand-based ventilation and innovative ventilation concepts (tangential, night, hybrid ventilation)
  • High flexibility from self-supporting stand- alone solutions (master/slave) or BMS connection, as well as simple scaling for expansion/re-equipment

Decentralised control intelligence

  • Independent, demand-oriented and energy-efficient control of the units
  • Manufacturer know-how integrated in the unit, wired and tested at the factory
  • Open bus communication and simple expansion/ scaling capacity
  • At least 50 % savings for investment/installation costs for the building automation system (BAS)

Cost savings

  • Significant reduction of software/hardware data points and DDC costs thanks to more compact components resp. LTG boards
  • Considerably reduced wiring work and error risk on the construction site

Verified/open systems

  • Integrated and product-optimised control circuits for room temperature and air quality as well as heat recovery optimisation
  • Open communication by use of Modbus as a protocol and available gateway components and converters


  • Inexpensive stand-alone solution for small zones (e.g. renovation of partial areas without BMS connection)
  • Subsequent switching to a building management system resp. existing system is possible
  • Subsequent expansion using different sensors without additional effort/module
