1 Product range overview
DXR1 and DXR2 room automation stations are perfectly suited for creating the
ideal comfort conditions for the room user. They measure room air temperature,
air quality (CO
2
), and humidity, and control fan coils, air volume flow, heat
pumps, chilled ceilings and heated ceilings, chilled beams, radiators, and floor
heating.
Moreover, the DXR2.. room automation station can be supplemented with
lighting and shading functions by adding the KNX PL-Link module.

The DXR2 room automation station can be flexibly configured, regardless of
available inputs and outputs. The following tested and flexible applications are
available, needing only to be configured. The following applications are
available:
● Air temperature control/variable air volume control (VAV)
● Fan coil units
● Heat pumps
● Chilled ceiling/ceiling heating
● Chilled beams
● Radiator/floor heating
All configurable DXR2 room automation stations can also be combined with
lighting and blinds applications.
Configurable applications meet the functional scope per VDI 3813 and permit
achievement of energy class A per EN 15232.
Information is centrally collected and evaluated to operate the entire system in
an energy optimized way. Each application is already set up to have all the
relevant information that can then be read without additional programming.
Energy relevant information includes:
● Ventilation system: Heating/cooling demand (optimum supply air
temperature), air demand (optimum supply air pressure or air volume)
● Heat pumps: Source demand
● Hot water/chilled water (2 pipe): Heat demand, cooling demand,
heating/cooling (changeover), etc.
● Chilled water system: Cooling demand, etc.
● Hot water system: Hot demand
Engineering central control or central measured values is child's play: Simply
enable prepared functions already available in the applications (no additional
programming required).
The functions include:
