Solutions for building automation

Building automation

The demands on modern building automation systems are increasing all the time. The focus is on the control, convenience and intelligent linking of systems and their communication options. As complexity increases, the need for the greater surveillance and transparency of electrical building equipment is also growing in the form of centralized and decentralized information sources that display status, operation and error information.
