Questions about underfloor heating with geothermal energy

So, I just followed the tip to check the valves. In the attic they are open, as well as on the upper floor. On the ground floor they are perpendicular to the pipe, so closed.

Can I now open them WITHOUT FURTHER ado? Or will something blow up in my face then?

Can I open them now WITHOUT ANY PROBLEM? Or will something blow up around me?

Our sanitation guy told us, "the tile guy should simply close those things, he should know how it works. If he forgets to open them again, we can just..."
So: Yes!

Please report your success, if it happens.

So, I'm slowly starting to freak out here.

Last night, just to be safe, I copied my neighbor's settings because his place is cozy, I just came into the living room and..... 17.9 degrees!!!!! What's that supposed to mean?

I opened the valves for the ground floor yesterday. The guest bathroom, which is also on the ground floor, is noticeably warm. That's how it should be.

The guest toilet is also connected to the HK distributor on the ground floor? Is the central return in the HK distributor on the ground floor possibly still closed off, so that the guest toilet is only heated by heat transfer from the water? Is there still enough pressure in the pipes? I think 1.8-2 bar is normal for us.

I was only able to open one blue valve and one red valve yesterday, so the supply and return.

Hello,

I could only open one blue and one red valve yesterday, so supply and return.

Called the handyman? The weekend is not going to be warm
