7 Rooms and room segments

Each DXR2 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. 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. 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.

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.

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.
