i forgot one step.
it's importent
check on display
go scroll down to "Version"
after powerbrake he lost signal and has no memory
there stand 14kw 24 kw or 28kw
i think on yours stand 14kw and you have a 24 kw version.
go to "Fachmannebene" put the code on to
the code is 1919 (It's the year when brötje starts building boilers)
push ok and stand now a refresh warning on display
go out with the up buttom
check again version display
24kw
give me a response of your software stand number and i come again
with instructions.
tip : push the down and minus buttom together and you have all information on tap.

function only at display mode like the same on your video.
never play on next side
