Abstract: An assembly for installing building systems engineering units includes a housing, which comprises a control device for carrying out an electronic function, and a base module which is designed for fastening the housing for a pre-determined installation situation. The housing and the base module are designed for fixed but removable connection so that the housing can be connected to a base module adapted to the respective installation situation in dependence on the installation situation. The modular sub-division of an installation unit into a base module and a housing, which comprises the control device for carrying out a defined function, can significantly reduce the diversity of variants.

Abstract: Local technology modules automatically execute given functions as part of process automation. Each technology module has a memory storing module-specific information about the respective function of the technology module and its tie-in to a measuring point, open- and closed-loop control system. During an initialization phase, this information is transmitted to a central communication device, where it is stored for access by an operator communication and monitoring device. It can thus automatically add the information to its operator communication and monitoring interface.
