Use
Starting with Desigo V5, PXC3 series room automation stations with Total Room
Automation applications (TRA) can be used for buildings with more sophisticated
requirements on functionality and flexibility. TRA is used when several disciplines
(HVAC, lighting, shading) are combined to form one total solution and when total
flexibility is required. TRA is perfect for solutions optimizing energy (class A)
without loss of comfort.
Functions
A PXC3 series room automation station can assume control for multiple rooms.
These programmable room automation stations provide the infrastructure to
provide and process system- and application-specific functions.

Architectural building grid (also called room axis).
2)
If V6 applications are loaded into a V5.1 device, less rooms are supported,
because V6 applications require more memory space.
To find out, DCM features the Load calculation tool.
