Multisegment applications always ensure full coordination of individual
electrical and mechanical installations of jointly used room control in the room
segment. All HVAC controllers (e.g. temperature or fresh air) is automatically
managed by the system when rooms are combined or separated and
interconnected with the correct segments.
On VAV plants, supply air and extract air volume is correctly coordinated over
all segments to achieve the preset setpoints for the room.
In other words, it is possible to combine multiple supply air VAVs, with multiple
extract air VAVs to form one room. A maximum of one supply air and extract air
VAV can be connected to each DXR2 in this multisegment application.
The DXR2 responsible for room control recognizes a fault to one VAV actuators
or DXR2 controller in a multisegment application. If physically possible, the still
active VAV actuators will attempt to compensate in this case for the fault VAV
actuators.
Room operator units can be connected to various DXR2s on multisegment
applications. All displays and entries on room operator units are synchronized
as soon as the DXR2s are combined to one large room.
Existing assignments of light and blind switches are retained when merging
rooms to multisegment applications. The same applies to dividing up the rooms.
The assignment can be reconfigured within a room as needed.
The Desigo CC management platform can also be used to combine or divide
rooms. Desigo CC permits the user to combine the HVAC electrical and
mechanical installations to one room or divided them up again. Existing
assignments to light and blinds switches are unaffected.
