There is a different approach in room automation with regard to flexibility, sizing, use, and reuse versus on primary plants, for example, air handling.

Functions are required here to centrally switch all rooms with a specific room state through the entire floor or switch lighting in rooms at a specified time. The same applies to shading systems that deploy the blinds to a safe position during high winds based on a weather station. Building users are increasingly requiring flexible use of rooms. For example, the rooms are newly rented out, or rooms are increased in size using partitions and designed to the current use.

Building automation and control expects the building automation and control system to do this, or for the room automation to automatically adapt.

On the one hand, central functions can control the room operating mode as well as centralized control of lighting and blinds over multiple room automation stations. Protection, service, or emergency functions can also be implemented over various devices.

On the other hand, flexible room management can be implemented with Desigo room automation and PXC3 or DXR2 room automation stations.

Repurposing can be quite easy using the separation between room and room segment. Coordination takes place in the room between HVAC, lighting, and blinds, set data points are calculated, etc., and then sent to the assigned room segments. The physical data points are located in the segment to control aggregates and components.

The entire Desigo system prefers the use of BACnet/IP to avoid expensive gateway solutions. This requires careful planning, sizing, and implementation of BACnet and IP networks.
