Still setting up and testing my new Vaillant.

Firstly I have attached some screen prints of my set-up, could you advise if my settings correct.  I am trying to achieve:

Internal Temp: 22C
Curve: 0.2
Manual setting
24 hrs run time

Secondly.  My flow temperature is a lot higher than the target being set by the Heating Curve.  Its 17C outside at the moment so I should see a flow temp of 25C according to the curve, but the app, sensocomfort, and my temperature probes are seeing 27C.

Some addition data that may be relevant:  Typical power 400 watts consumption, compressor running at 25%. HP is cycling every 2hours (which is to be expected).
