Building Technologies Temperature measurement 28 Feb 2009
7.1.5 Temperature sensor outputs on the Konnex bus
To map the local temperature measurement in a building automation and control
system, the following two output communication objects are used:
RXB... Room controller
10384Z15en
Effective room temperature
Room temperature output
R
O
+
The value of the communication object
Room temperature output is not filtered (not
smoothed).
Sending takes place only if room "Room" is parameterized for the temperature sensor
B1.
The value transmitted as the
Effective room Temperature is the filtered (smoothed)
value of the communication object Room temperature output or Return air temperature
output, or the average (see 7.1.3):
Room temperature output (output communication object)
Effective room temperature (output communication object)

Invalid temperatures are mapped to the bus as 0 °C.
In LTE mode, the room air temperature from directly connected sensors is mapped as
