On the technical manual there are no instructions to reset it without the keyboard, the keyboard remains locked and restarts when sent.
When I'm off I also turn on only with the mains but nothing
If you have the installation manual, there shou;d be a section on defaulting the unit, can you find the section about defaulting the codes only?
default the codes and then follow the procedure from first start up that is in the manual.
If you are still struggling call Tech support in Italy and or a local installer.
Not sure I can help any further at this moment in time unfortortunately.
