Bus supply for RXB controllers

RXB controllers can work without bus supply if the following conditions are adhered to:
• Parameterize only using the HandyTool (not with ETS3 or ACS).
• No integration in a building automation and control system (e.g. DESIGO, Synco).
• No changeover mode (sensor signal via bus).
• No outdoor temperature via bus
• No master/slave combinations.
Otherwise, the Konnex bus, used by the RXB room controller for communication,
requires a bus supply.
Each controller consumes 5 mA. The supply has to be selected according to the
number of controllers. We recommend the following products:

RXB Konnex controller communications

RXB Konnex controllers support communication as per the Konnex specification.
Among the modes defined in this specification are the following:

• S-mode

= Standard mode
• LTE mode = Logical Tag Extended Mode
This is a new mode which supports simpler
engineering and is used in conjunction with Synco.
1.8.1 S-mode
This mode corresponds to EIB communication. Connections are established via ETS3
Professional and group addresses.
This ensures a link to the existing EIB environment.
For more details of this mode, refer to the EIB manual.
