Problems with VentoBox

Hello,

I have a new P2S printer.
I bought a VentoBox and installed it today. Everytime i start the print my VentoBox gives an error. See picture.
I tried several solutions from the internet. Disconnect the connector and installed again on the motherboard. I cleared all the air flow openings and startet the VentoBox on 50% instead 100%. I tried also the Gcode advices on internet but all failed or gave errors. I am little desperate and dont know what todo next. I cant and i sont know how i can see if the fan is working at all. I hope you guys can help me out. Please be gentle with me i am not a technical engineer.
