Bus supply for RXB Konnex controllers

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

RXB Konnex controller communications

The RXB Konnex controllers support communications as defined in the Konnex
specification.
This specification defines the following modes among others:

• S-mode

= Standard mode.
• LTE-Mode= Logical Tag Extended Mode
This is a new mode which supports simpler engineering and is used
with Synco.
1.7.1
S-mode
This mode corresponds to EIB communications. Connections are established via ETS3
Professional and group addresses.
This ensures a link to the existing EIB environment.
Refer to the EIB manual for more information on this mode.
