Calibration Temperature sensor on an MP2 5000 GX

[eibdoktor (Axel Grossmann)]

I have commissioned my new MP2 48/5000/70 GX now, it is running, but tells me frequently, that the temperature is only 5°C, although the BMS reports 11°C. So how can I adjust the offset of the MP2 temp.-sensor input? I have searched the documentation, this forum and other forums, but with absolutely no feedback or solution.
