IDM iPump 2-8 Optimization / Adjustment

Hmm, you can't see everything in the pictures, but if the affected room on the left is shown in the top picture, then the flow rate there is zero?! Please take another picture where the sight glasses and drives are visible at the same time.

Sorry, that wasn’t quite clear from me. The second from the left is the affected room. Here it might be better visible.

Well, could it be that Child 1 and Child 2 are swapped? Or Child 2 and Hallway, etc.?

Tjoa, could it be that Child 1 and Child 2 are swapped? Or Child 2 and hallway, etc.?

I would have to test that exactly, but honestly I don't expect it. Otherwise, one of the other rooms should be warming up right now, which is not the case. (Except the bathroom, but here the valve is also open because the thermostat is currently set to 3) The floor also feels "warm," but for some reason the entire room does not warm up accordingly. Currently, it is at least 17.4°C.

As a test, I placed the thermometer on the floor earlier to see the temperature directly at the floor. Here it is at least 19°C, which in my opinion is too low with a flow temperature of currently ~33°C. Obviously, the room doesn’t really get warm because of that. But what’s causing it...

The other rooms, where the valve is also closed everywhere, are significantly cooler. So the assignment should be correct.

I also don’t know if everything is really set optimally; maybe someone with more knowledge should take a look.

What are the temperatures around it? Is a ventilation installed?
