Solving unknown registers - is there some available source of data which can help me to fill the gaps

[ivoIT1]

I have to say that it is interesting project, I have not hope that it will work but most was translated to real signals,
but still I have some unknown cmds which I would like to fix.
Technically it is interesting that the definition works even if the controllers are freely configurable, and maybe this is my problem:

What I know:
address 15: slave #2, scanned "MF=Vaillant;ID=UI ;SW=0502;HW=6201", loaded "vaillant/15.ui.csv"
address 23: slave, scanned "MF=Vaillant;ID=VR630;SW=0500;HW=6301", loaded "vaillant/23.vr630.cc.csv"
address 25: slave, scanned "MF=Vaillant;ID=VR630;SW=0500;HW=6301", loaded "vaillant/25.vr630.hwc.csv"
address 26: slave, scanned "MF=Vaillant;ID=VR630;SW=0500;HW=6301", loaded "vaillant/26.vr630.hc.csv"
address 50: slave, scanned "MF=Vaillant;ID=VR630;SW=0500;HW=6301", loaded "vaillant/50.vr630.mc.csv"
address 51: slave, scanned "MF=Vaillant;ID=VR630;SW=0500;HW=6301", loaded "vaillant/51.vr630.mc.3.csv"
address 7f: master #24
address 84: slave #24, scanned "MF=Vaillant;ID=VR630;SW=0500;HW=6301"

I really do not know how the system is decoding which circuit is for hot water, mixers or burners, and this can be my problem.

after clean up , I still have these command not decoded to real signals. I have removed the data part of it , but I have it too.

Is there someone who can recommend some documentation which give me direction to fill the gaps ?
as example : these telegrams looks OK, but in device 26 this [PBSB],[ID] is not defined, and I am pretty sure that this is just increasing temp measurement of hot water tank, but hot water in my case should be 25. This is why I do not understand how it is assigned and more it looks that someone just decide it , as all are coming from VR630 and there is not any detail info which is which and in my case they can be switched, as order in unit is : Burners, MIX1, MIX2, hot water. ( at least on the screen )
1026b504010d / 050000280405
1026b504010d / 0500002a0405
1026b504010d / 0500002c0405
1026b504010d / 0500002e0405
1026b504010d / 050000300405
1026b504010d / 050000320405

Anyhow good result if 80+% was decoded !
