Hello,
Im not from Germany and I noticed that this is only active community for Viessman , hopefully someone had similar issues and could help.
I have new Vitodens 100-w gas burner with Vitotrol 200-e thermostat which is having issues. Thermostat is constantly rebooting (daily) when i press any button. It looks like it was freezed and not sending correct temp to burner. From time to time also screen goes totally black and i need to reboot whole gas burger to get it working back.
Did someone have similar issues ? I already recieved new thermostat from Viessmann but issue is still there.
Regards,
J
