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.

But a heating system is much more complicated than a television.That’s not necessarily true. People are just used to modern conveniences. I clearly remember when you couldn’t do anything with a TV without carefully studying the manual, and nowadays, as soon as you want to go beyond the options the manufacturer offers (which can be quite basic depending on the brand), reading the manual becomes necessary.It’s similar with heat pumps. Any child can operate a refrigerator (which is also a heat pump). That’s because the manufacturer installs only a thermostat, and that’s it.
With a larger system, like for a house, the situation is different. The manufacturer doesn’t know what will ultimately be connected, so they only supply the unit and recommendations. What happens next is up to the heating engineer and the end user. One party sets the parameters based on needs and preferences, and the other is responsible for fine-tuning. Or you keep having the other party come back until everything works perfectly.

If there is a homeowner reading this who is still choosing their service providers: pick those who are passionate about their profession and the technology they install. I can’t choose my heating technician, but apparently he once worked for six years in factory customer service for Daikin. So, in theory, he should be quite capable. At least, he seems to have optimized his own home quite well, based on information from phone calls with him about technical possibilities.
However, what he actually delivers—or may have delivered during previous service visits—is very questionable.

Why don’t you start a thread? Otherwise, there is a forum for that, but I’m not allowed to mention the name.

I’ve also been tweaking the heating curve so that it’s 22.5°C (72.5°F) in my place. All thermostats/valves are fully open. However, I’m not sure if the settings are correct.
My heat pump is cycling like crazy, too.

Forum, but the name must not be mentionedI have come to believe that the Novelan WP is especially poor technical equipment. You really have to completely close the bypass valve and manually adjust everything. That’s why I would prefer gas. The system works flawlessly without any adjustment, and consumption figures are also accurate.
My Novelan still cycles twice a day and has an average compressor runtime of 45 minutes.
