Room
Each DXR2 room automation station 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. Room control includes all functions that apply to the entire room including Green Leaf or, for example, room temperature controller. A group ensures the connection between room function and room segment function.
So that multiple DXR2 can be combined to form a larger room. They can also be separated again at a later date to guarantee full flexibility.
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. The room segment includes all field devices and controls and controllers for the individual disciplines, e.g. the room operator unit, control of VAV actuators, or chilled ceiling control. Each room segment requires a connection to room control. Room control can take place on the same DXR2 or another DXR2.

Multisegment
Switching multiple DXR2s to one large room is referred to as a multisegment application. One of the DXR2 assumes room control for all switched DXR2s. Room control is disabled on the other DXR2s. In addition, all room segment functions, on the various DXR2s, are connected through grouping with the still enabled room function of the one DXR2.
