Building Automation

The benefits of AS-Interface – such as the simple, cost-saving installation and high degree of flexibility – have now established themselves in building automation. Numerous companies are already using the AS-i installation system, for example for controlling fire and smoke dampers, shutter drives or heating and cooling ceilings using analog output modules. Damper drives with flow regulators can be connected to the controller through the MP-Bus gateway. It is also possible to process EnOcean signals from wireless pushbuttons and sensors over AS-i. During your planning and application implementation phases we can be at your side and are open to application-specific special solutions.
