7.1.6 Temperature sensor input from Konnex bus
The signal from the sensor connected to the bus takes priority. The signal is not
averaged and no sensor correction (page 157) is done.
Since KNX temperature sensors are available from a variety of manufacturers, the
name of the S-mode output communication object varies accordingly.
