Also, the return temperature should not rise too quickly during the first 15 minutes.

In well-balanced systems, the return temperature should only start to increase after 8-10 minutes.

That doesn’t happen, quite the opposite.
Didn’t you have an issue with the return sensor?

Nothing. Let it run through and don't adjust anything further.

We currently use 20 kWh/day for our Viessmann heat pump. It is a major renovation of a 170 m² (1,830 sq ft) living area.
