Description of the controllers / Airtronic Basic for air handling units Rosenberg
Airtronic Basic controllers have been specially designed for the control of Rosenberg housed instruments and they represent optimum comfort and safety in operation, monitoring and service of the system. The most up-to-date DDC technology is used. Amongst the advantages of this technology, the option of customer specific adjustment should be emphasised for very many applications.
Complete operation is carried out remotely via a remote control display on which all fault reports and conditions of the service are shown in writing.
The Airtronic Basic series is manufactured in accordance with VDE (Association of German Electricians)
guidelines. It is available for control of fans with belt drive by standard motors and fans with direct drive by
controllable external rotor motors.
Freely programmable controller with microprocessor, which allows customers' special requirements to be met
