The
HVAC Status (non-standard DPT)
according to the KNX specification sends the corresponding
hex value for the currently set operating mode. If several statements apply, the hex values are
added, and the status symbol then outputs the added hex value. The hex values can then be read
out by a visualization.
The following table shows the hex values associated with the individual messages:
