Hello everyone,
In my apartment, the room temperature is not right at all.
Although the thermostat is set to 22 degrees, the room temperature sometimes reaches 25 degrees.
I have done some research and read that it might help to reduce the flow temperature. Does the return temperature also need to be reduced?
Could someone please tell me, based on my photo, where I can adjust the flow temperature and where I can adjust the return temperature? Maybe also a tip on what values I should set?
Thank you very much

The valve marked in the top right of the picture is likely the supply line since it is set to 30°C (86°F). This is already quite low. The flow rate is probably too high, and the thermostat cannot regulate any lower because it is at its minimum setting.
It will probably need to be recalibrated (hydraulic balancing).
From a professional standpoint, I would say: RTFM 😎 or let the expert who “messed this up” take care of it.
Considering we are supposed to be in the Industry 4.0 era, this looks pretty “makeshift” :p
One more note: At the bottom, two electrical cables are improperly connected using a terminal block without proper enclosure. This needs attention. It’s dangerous!

knalltüte30 Dec 2020 21:47I can still see the plate heat exchanger from Danfoss in the middle. What is it doing there? (Domestic hot water station?)
Are you sure that this is the heating circuit manifold for the underfloor heating?

How old is the heating system?
If it is very old: controllers like the marked one tend to clog over time, and a pin inside can get stuck. Then it no longer adjusts properly.
Under the marked controller, there is a device from Wilo. It looks like a pump. As a first step, I would try turning the controller slightly counterclockwise, hoping to reduce the flow rate for the underfloor heating.

Thank you for the quick reply 🙂
I have already reduced the flow rate as well; I think the previous owner of the apartment tinkered with it too much.
I might still try lowering the supply temperature a bit.
If that doesn’t help, I’ll have no choice but to call a professional 😀
I’ll also take a look at the electrical cables, thanks!
