Vitotrol 300E - PIN code for service menu?

Good morning all,

Does anyone know the factory setting PIN code for the service menu on a Vitotrol 300E? I’ve tried Viessmann support and they are not aware of it 🤦🏼‍♂️

Many thanks

Search for the year when Viessmann was founded and you will have the Code 🙂

Thanks! I expected that in the menu I could force a software update but no.
