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
