Burning hotend - Rapido

HELP. I've gone completely dumb.

at first I have a symptom that the rapido does not heat up above 220C degrees and now I have the impression that it is heated to the max, i.e. up to 350C because the filament is on fire.

it is connected to the EBB36 can bus and the thermistor is PT1000 ( two lines)

How to check whether the thermistor gives true values??

here is my config
