20.2.1 Product range overview
Desigo RXB is an innovative range of controllers and room units. Data
communication is based on KNX/EIB technology.
Desigo RXB hardware
The range comprises compact controllers, easy-to-operate room units and
controllers in room-style housings. The input and output configurations of the
controllers, and the housing style are fully optimized to suit their field of
application. The HVAC functions are operated with standard room units or
controllers in a room-style housing.
Desigo RXB software
Each controller is loaded with a selection of application software which
contains the control program for the associated room or area within a room.
The ETS commissioning and service tool is used for the engineering and
commissioning of a network incorporating the Desigo RXB range. This tool also
supports the creation of communication bindings between KNX/EIB-compatible
devices (Desigo RXB or third-party devices).
