Hello
Out technician replaced the motherboard for Vitovent 300-W as I described in https://community.viessmann.de/t5/Lueftung/Vitovent-300-W-not-working-with-fully-functionality/m-p/3... but then I forgot to post the requested information.
Currently the LB1 panel shows that the maximum is 325m3/h even if the system can go up to 400m3/h. The technician didn't get any documentation, where the dip switch values described, all set to zeros by default.
What is the correct configuration?
Thanks,
Tamas
