DXR2 can control one room. One segment also belongs to the room in each
DXR2. The DXR2 includes the control function for the room as well as control
function for the associated room segment.
Each DXR2 includes, in addition to the control for the room, control for the
associated room segment. A room segment is the smallest indivisible element
in the building.
An application type includes all possible versions of an application. The
application type forms the starting point for configuring a DXR2 automation
station. Functions for the associated application functions are enabled or
disabled by selecting or clearing the function.
