Controller description / Airtronic D for Rosenberg fans
Airtronic D control devices represent the highest level of development of the Airtronic series and are based on the Airtronic Basic. In addition, operation is also possible with frequency converters as drive units for the fans, pressure, humidity and flow volume control and air quality measurement.
Control may also be linked to building control systems via a visualisation program. Remote interrogation and intervention are possible over a modem.
Airtronic D control devices cover the entire spectrum of control and drive control of air and air conditioning
technology.
