Control technology

A building automation system (BAS) is part of a building automation & control system (BACS) and is divided into three levels: the field level (e.g. valves and sensors), the automation level (e.g. DDC, ISP), and the management level (Baelz WinBas).

The BAS is located at the top level, i.e. management level. The automation level includes all of the building's monitoring, positioning, control, and optimization equipment.


Baelz control technology enables you to implement comprehensive concepts for industrial and building automation.
