Desigo room automation
Desigo room automation offers solutions with greater functionality and flexibility allowing for energy-
optimized plant operation without loss of comfort (efficiency class A).
The DXR1 and DXR2 room automation stations are perfectly suited to exclusively automate heating,
ventilation, and air conditioning in a room. In addition, the DXR2 can be extended with lighting and shading
functions by adding devices with KNX PL- Link.
The PXC3 modular room automation stations are used in buildings with multiple disciplines for room
automation (HVAC, lighting, blinds) all combined in one system.
Desigo RX
Desigo RX is a proven room automation product range featuring comprehensive communications and
application functions for individual rooms. The product range consists of a series of communicating room
controllers RXB with operator units and predefined applications for HVAC, lighting, and blinds. Desigo RX
room automation is capable of autonomous operation. Integration of LonWorks or KNX network via the
system controllers provides for additional functionality.
20.1 Desigo room automation
New guidelines to save energy and lower operating costs and greater requirements for comfort and design
require a more sophisticated interaction between a building's various technical installations. The modular
and compact room automation stations combine lighting, shading, and HVAC in one total solution and
provide a direct connection to the automation stations via BACnet.
