3.6 Examples for lighting and blind groups
This page shows two typical examples of the application of lighting and blind groups.
These examples illustrate:
– Why the RXC controller has to be treated as the basic unit for lighting and blind
groups
– How overlapping groups occur and how these are handled
The diagram below shows how the blind outputs are connected, and how groups are
allocated in a corner office (TCR4):

The groups defined in the diagram above have the following characteristics:
Group Description
South All blinds on the south-facing façade form a group which is operated
remotely via the system (e.g. “Down” at night, “Up” in the event of a storm).
East In the corner office, the blind on the east façade is disconnected from the
“South” group and assigned to the “East” group, so that it provides shade
only when required.
The diagram below shows two rooms with blinds and lighting zones. Assumptions:
– TCR5, Production area: blinds and lighting for the entire production area, operated
by manual switches
– TCR 6, Warehouse: blinds normally down, lighting only on when required

AOw Blind group for whole building façade
AOx Lighting group for Production area
AOy Lighting group for Warehouse
AOz Lighting group for entire floor: “Off” at night, via command from system
