Underfloor heating air-water heat pump. House too warm when the sun shines

Hm, is it stuck? You had 2l/min earlier, right?
Was the heating on in between?
Is the heating running now? Turn it to see if something moves. Do you already have the thermometer?

Yes, 2 liters were set earlier. The heating was running a moment ago and all were up, but this one is still up now, the others have stabilized again. The heating has been off for 58 minutes. I don't dare to turn it further because a bit of water sprayed out today in spring mode. Unfortunately, I don't have the thermometer yet.
Now I am at a loss.

Is the heating circulation pump running right now?

Hi,
How have the temperatures changed in the bedroom-dressing room and hallway enteo. What about the bathroom?

Good morning, nothing has changed in the last 24 hours.
This morning at 7 o'clock:
Bedroom: 22.5
Hallways: 23.1
Bathroom: 20.8
Utility room/ 20.6
etc.
Only the power consumption has dropped from 30kWh to 14kWh.
:-(
What is the reason for this, how can it be that the hallway stays so hot? But the bathroom is cool.
Sleeping is unbearable.
I will adjust the heating curve from 29.5 22.0 0 to
29 21 0.
The float valves are now all back up, since the heat pump is currently running.
I will check again later regarding the bathroom.

How have the temperatures in the bedroom-dressing room and hallway developed? What about the bathroom?

P.S. The float in the bathroom was apparently stuck, it is back at 2 again
