Has anyone here had much experience with the old Velta (now upnor) UFH systems

I have a customer who has a few issue and i'm trying to find some info.
I've managed to download the settings doc to see the installer settings but not sure how to get into the settings menu on the Veltamat 3D unit.

The issue is the floors are not getting hot enough in cold weather even tho the outside sensor is showing lower temps. I was wondering what the curve was set to and hence looking for info on how to get to the installer settings.

Flow temp seems to be 31-35 and return around 30

any help would be much appreciated, thank you
