Viessmann 100-w B1HA Parameter Question!!

obg8 Member Posts: 22
So I'm trying to set my boiler up and I noticed a parameter is wrong..

So in the manual (link below, page 40) it lists all the parameter settings

Parameter 7 for me is set to 1

It should be set to 2 (b1ha)

How do I adjust this?? It won't let me use the up/down arrow

    Are you sure you don't have the combi boiler? Isn't that setting a factory one?

    @gschallert Setting is a factory one, the guy from viessmann tech support said they are all like that with the control board from the manufacturer. Said I cannot change it.

    Do you have a combi or a heat only model?
