DXR2.. can automate up to two rooms for heating, ventilation, air conditioning, shading, and lighting, whereas DXR1 can automate one room and heating, ventilation, and air conditioning only.

The stations communicate with each other and other system components, depending on the type, via BACnet/IP (DXR1.E../DXR2.E..) or BACnet MS/TP (DXR1.M../DXR2.M..). The room automation stations have a set number of I/O data points and an onboard interface to KNX to connect field devices. The automation stations are delivered with preloaded applications and only need to be configured.

A comprehensive library of proven, standardized applications is also available and can be used instead of the preloaded applications. Buttons, sensors, and actuators for lighting and shading are connected to the room automation stations via the KNX PL-Link.

The preloaded and proven standardized applications in the library are configured using ABT Site and offer a great deal of flexibility since the inputs and outputs of the DXR1../DXR2.. can also be configured in addition to the functions.
