Airtronic D for Rosenberg fans

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.

Freely programmable controller with microprocessor, which allows special customer requirements to be met

Operator unit with 4-line LCD display for messages in writing, 20 characters each

Suitable for front installation or wall mounting

14 digital message inputs (fault messages)

(e.g. subsequent insertion of a cooling sequence or heat recycling possible)

Operating voltage 24V AC, max 10 VA

Recyclable housing

Connection option for a local printer for regular monitoring
