I found a working solution to connect my Bequem Burner to my PC without direct-cable!
It works this way:
Bequem -> Lantronix comserver -> dlan (powerline) -> my PC
With this solution i can change "Önskad panntemp" and a lot of other parameters, which are usually set on the burners display, from the far!
I can also switch on and off the burner with my PC.
