Viessmann Vitodens 100W - Changing display from degrees Fahrenheit to Celsius

I just installed a Viessmann Vitodens 100W Combi boiler. Does anyone know how to change the water temperature display to degrees Celsius? It's not covered in the manuals.

    The control shared above is an older 200 series control. If the boiler you have is a B1KE model of either size, it is the third question on the commissioning assistant when you started up the boiler. to access the assistant again

    hold "OK" and the "three lines button " for 4 seconds (access service menu)

    arrow up and down to select "Basic Settings"

    hit "OK"

    arrow up/down to "Commissioning Assistant"

    hit "OK"

    If you have a different model (100-W has been used through several model generations) let me know the model number and I can find the info for you
