How to set the heating temperature above 55 degrees on my Viessmann Vitodens 111-w?

Hi I was wondering if anyone could help me with raising the central heating temperature above 55 degrees on the above boiler.

Instructions read to go into the menu using the three bar icon and then use the up arrow to increase temperature.

However I can’t set the temperature any higher than 55 degrees. I can use the up and down arrows below this top temperature of 55 but no higher. It seems 55 has been set elsewhere as the maximum temperature.

Any ideas? Thanks very much!

Most modern boilers have a settings menu, where you can set the maximum flow temperature.

Here is a video of the settings menu on a different Vitodens model, the 100W. It might be the same for yours. Maximum flow temperature seems to be setting 8. Apart from finding the video, I know nothing about this, so it would be at your own risk!
