3.4 Defining lighting and blind groups
In addition to HVAC functions, the integrated applications of DESIGO RXC include the
control of lighting and blinds. This makes it necessary to define groups for these
purposes too, whether in response to HVAC conditions or differing patterns of room
occupancy.
Whereas the room is the basic element for defining HVAC groups, in the case of blinds
and lighting, the definition of groups is based on the RXC controller. The diagram below
shows the principles which apply to the definition of blind or lighting groups.

Four groups have been defined, covering the complete area:
Group Covering…
AOp All rooms
AOw A subset of AOp
AOx A subset of AOp
AOy A subset of AOw
Note: p .. y can be numbers in the range 1 .. 200.
In summary, the following rules apply to the definition of lighting and blind groups:
- The RXC controller is the basic element for the definition of groups.
- The window-blind control functions of the RXC controller can be assigned to several
blind groups simultaneously.
- The lighting control functions of the RXC controller can be assigned to several
lighting groups simultaneously.
- The smallest unit is the controller, i.e. the lighting zones or blinds connected to a
controller always belong to the same group(s).
