Siemens RXB (KNX) application library RXB Description of functions for FC-10, FC-11, FC-12, FC-13 CM110385en_08
Building Technologies Temperature measurement 2013-06-17
Subject to the appropriate configuration and integration, the room temperature/return
air temperature is read by the controller immediately after a reset.
For a Konnex sensor the send heartbeat must be set to "Cyclical sending enabled"
The situation is slightly different in LTE mode: Here, each signal has its own specific
name, and the room temperature and return air temperature therefore each have their
own communication object.

For the FNC10, FNC12, and FNC18 applications, the outside air temperature must be
available as a bus information. It can be read via the next S-mode communication
