Innovative Control Technology / Connected Intelligence

Demand-based ventilation without the need for a central building automation system:
decentralized control Intelligence

Connected Intelligence offers an inexpensive and flexible automation solution for LTG air-water products. The System permits demand-based and room-matched ventilation and air conditioning with or without a building automation system (BAS). Inexpensive and simple to install, the units can be daisy chained together with a single cable to form a network that is compatible with the existing building control system and compatible with most room sensors.

Innovative automation solution

  • Relocation of the control tasks for energy- efficient air conditioning directly at the unit within the room
  • Simple implementation of energy-efficient demand-based ventilation and innovative control strategies (tangential, night, hybrid ventilation)
  • High flexibility from self-supporting stand- alone solutions (master/slave) or BAS connection, as well as simple scaling for expansion or customer churn

Decentralized control intelligence

  • Independent, demand-based 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
  • Reduced controls and commission costs, not dependent on the building automation system

Cost savings

  • Significant reduction of software/hardware data points and DDC costs thanks to more compact components resp. LTG boards
  • Major reduction in control wiring and associated risk of wiring errors on site

Verified/open systems

  • Integrated and product-optimised control circuits for room temperature and air quality as well as heat recovery optimization
  • 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 BAS connection)
  • Subsequent switching to a building management system resp. existing system is possible
  • Subsequent expansion using different sensors without additional effort/module
