I think I finally have a solution in OH2

There following issues appeared

Issue #1 - Dealing with DPT 20.105
Frank explained the way how OH treats DPT 20.105. Different than expected.

Issue #2 - ETS5 device configuration
It´s a generic application, so I had to find out the proper configuration of my air conditioning system. E.g., Indoor unit has fan mode=no". Tested it out by writing and then reading the mode, for instance. I also tested mode settings with the remote control.

Issue #3 - Bus reply strings are not identical to Intesis handbook
My air conditioning system should theoretically have a mode “Dry” and exactly use this string. But it used “Dehumidification” instead. Took a while to understand, why a sent out mode didn´t show up in the sitemap selection.

My solution looks like this for interface

Panasonic Etherea AC units to KNX Interface with Binary Inputs - 1 unit
PA-AC-KNX-1i, 4 binary inputs
