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 140) is done.
Since KNX temperature sensors are available from a variety of manufacturers, the
name of the S-mode output communication object varies accordingly.
KNX temperatur sensor
... or ...
If the room temperature/return temperature is available as information on the bus, it can
be read with one of the following S-mode communication objects:
Room temperature input (Input communication object)
Return air temperature input (Input communication object)

DPT_Value_Temp
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"
