21.2 Application types
The DXR2.17C… automation station can be flexibly configured, depending on
available inputs and outputs. The following tested and flexible application types
are available, needing only to be configured:
● Room pressurization, temperature control (HvacLgtShd14) - provides the
HVAC and pressurization functions for the room segment(s) belonging to
one HVAC zone.
● Room pressurization, advanced temperature control (HvacLgtShd15) -
provides the HVAC and pressurization functions for the room segment(s)
belonging to one HVAC zone.
● HVAC Fume hood (Hvac16) – provides all the application functions for fume
hood(s) belonging to a lab room zone.
All configurable DXR2s can also be combined with lighting and blinds
applications.
21.3 Room and room segments
This application type uses the room automation room/segment structure. The
application type handles multiple segments that can be connected to multiple
controllers. It applies to room coordination functions, HVAC coordination
functions, HVAC device components and connects to central functions with
room automation group data definitions.
The application architecture defines a room as equivalent to a temperature
control zone. Multiple terminals serve one pressurization control zone if they
are also in the same temperature control zone.
One segment may include a supply terminal, an extract terminal, or both. A
segment may not include two supply terminals or two extract terminals.
The DXR2.E17C controls one segment and the DXR2.E17CX controls two
segments. Both room automation stations can coordinate multiple segments.
The room pressurization application types coordinate up to 20 fume hoods in
one room.
This fume hood control application type fits into the room automation
application architecture as a segment, not a full room/segment application. The
application type implements stand alone control for a fume hood and is
designed for use with one automation station dedicated to one hood.
