Features
Programmable
The DXR2... automation stations provide the infrastructure for system and application-specific
functions and can be programmed.
Compact series
The compact build permits mounting in narrow spaces and on standardized DIN rails, and is
particularly well suited for compact panels or plants with integrated panel.
Plug-in terminal blocks
Plug-in terminal blocks to easily exchange room automation stations.
Use
● Desigo Room Automation applications combine multiple disciplines (HVAC for pressurized
rooms and fume hoods, lighting and shading) into one comprehensive solution.
● Desigo Room Automation offers the highest level of flexibility for energy-optimized solutions
while satisfying requirements for pressurization, ventilation and comfort using standard tools
and established workflows.
● Desigo Room Automation applications can be enhanced with lighting and blinds via KNX PL-
Link.
