ᐅ Underfloor heating with an air-to-water heat pump. House gets too warm when the sun is shining.

Hello everyone,
I have a general question.
We moved into our new build four months ago. The living area on the ground floor has three large floor-to-ceiling windows facing south. We have underfloor heating and an air-to-water heat pump.
It provides a really comfortable temperature inside the house, but we have a problem – whenever the sun is shining in winter, even if it’s -2°C (28°F) outside, the temperature suddenly rises to 24°C (75°F) in the living room. It gets uncomfortably warm in here, and the underfloor heating can’t be turned down quickly.
Should we assume that the large floor-to-ceiling windows are responsible for the heat gain? A photo of the south-facing side of the house is attached.
What would you do – always lower all the blinds as soon as sunlight is forecast? That seems quite annoying...
We have motorized blinds controlled by Somfy. Would you consider buying a sensor that automatically lowers the blinds at a certain temperature?
Thanks in advance for your replies.

Then turn the top to adjust the flow (be careful at first so nothing breaks, but your tubes look similar to mine, so they should work the same. If it won’t turn, please wait for the heating technician)I’m at the controls now, I’ve loosened the lower nut and want to turn the top part. I don’t want to apply too much force anymore, but when I press lightly, the upper black wheel doesn’t move. Which way should I turn it to reduce the volume? Counterclockwise? We have this heat again this morning, it’s unbearable in the bedroom.

And immediately check whether the main bathroom can be made more spacious.

The refrigerant in the heat pump also has an optimal operating range, and the temperature difference between supply and return is important for this. The ideal temperature difference depends on the refrigerant, but I’m not familiar with that... Okay, I figured it out. I’ve now adjusted the controls a bit back and forth.
For example, I reduced the energy flow to the hallways and the master bedroom. I wanted to redirect that energy to the bathroom, but I couldn’t set it higher than two without water spraying out, so I quickly turned it back down.
I’d actually prefer 2.5 or three there in the bathroom, but right now it’s just two. Well, I’ll keep an eye on it.
I hope I haven’t reduced the overall flow rate too much. I took quite a bit from the halls, where it’s currently at 23.2°C (74.2°F).

That's exactly right
And immediately check if the main bathroom can get more flowThis is how it looks now, see attached. On the ground floor, I wanted to increase energy in the living room and reduced it in the hallway. But the pipes, three in total for living areas, couldn’t really be adjusted well. And one is black. I didn’t dare to touch that :-/

Tonight you will get a first trend.
You can read the overall flow on all the tubes.
After 24 hours, the house has stabilized again; please provide feedback with the table then.
