RXB applications
RXB hardware
The product range comprises compact controllers and corresponding room units for comfortable control. The compact room controllers
are optimized to the respective application with regard to input/output configuration. HVAC functions are operated via standard room
units.
Communication is based on KNX S-mode. The fan coil room controllers communicate also in KNX LTE mode. KNX LTE mode is used for to
communicate with control equipment from the Synco™ 700 product range.
RXB software
Each RXB unit comes with preloaded application software featuring one or several applications (see next page).
The ETS software helps engineer and commission a network with RXB units.
In addition, the Synco™ tool… and room unit QAX34.3 by Siemens can be used for commissioning and parameterization.
Connection to the Desigo building automation and control system
Desigo PX KNX allow for flexibly connecting RXB controllers to the Desigo building automation and control system, and hence acts as a
gateway to BACnet. The connection provides access to other functions such as time schedules and central control of setpoints.
RXB thus fits into the overall expandable modular system, and ensures long-term cost-efficiency.
Integration into Synco™
The Synco™ central control unit RMB795 is used for controlling and monitoring the RXB controllers in a Synco™ system.
