ᐅ Underfloor heating on the first floor is no longer working.

Hello, we need some help.
The underfloor heating on the first floor is no longer heating, but it still works in the ground floor and basement.
The pressure gauge shows 1.2 bar. The heating system was serviced at the beginning of the year. I suspect that our 5-year-old godchild might have adjusted some valves.

I noticed that when I turn the red valves in the ground floor to a vertical position, the supply pipe on the first floor gets warm, but that’s all.
Could it be that something is incorrectly adjusted?

See pictures.

Try searching for "manual radiator valve" and you should find what you need. They may look different but serve the same function. Use the standard 30x1.5 (1.18x0.06 inches) size and it should fit.

I want to have the same ones as the old ones; I have already screwed on different ones myself.

The function is the same. But you need to know what you want.
