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 directly on the damper shaft, and is designed for VAV and
FPB.
Plug-in terminal blocks
Plug-in terminal blocks to easily exchange room automation stations.
Integrated actuator
The actuator gear base is integrated into the housing of the actuating DXR. For dampers
requiring up to 88 lb-in (10 Nm) of torque.
Use
● Desigo Room Automation applications combine multiple disciplines (HVAC, lighting and
shading) into one comprehensive solution.
● Desigo Room Automation applications can be enhanced with lighting and blinds via KNX PL-
Link.
● Desigo Room Automation offers the highest level of flexibility for energy-optimized solutions
while satisfying requirements for temperature control, ventilation and comfort using standard
tools and established workflows.
Preinstalled applications
