Hydraulic balancing, disable single room control?

Whereas it must be said that what works in the cold does not necessarily have to work during the transition period.

Definitely. During the transition period it is always either too cold or too warm. That is also why the advice is to wait and not rush to the heating system at the first low temperatures to try and optimize it supposedly. That brings absolutely nothing.

In my opinion, it is a process of approximation and no heating engineer can do that for you.

Here too, yes, absolutely, especially since every house is completely different and also reacts differently. The heating engineer can only provide an approximate setting; the rest you have to do yourself. Or you leave it, that is up to each individual.

I will also have the problem of timing when I look at the operating hours and burner starts like this...

Hey everyone!
So, I had some time and dared to tinker a bit with the heating...

The actuators are still electrically connected!
But I was able to "turn them up" and then they clicked into place... Is that a function to open the motors manually? Does anyone have these motors and can tell me something about it?

Then I turned the black star grips and set all the red floats to 1...

Is everything correct so far?
Or did I do something wrong?

I have attached the set heating curve for you...

You can set the marking on the actuators to "open" then they are continuously open and without function. I hope you wrote down where the dampers were before you started turning them. I say this in every thread here. Do not just turn them around like that.

By turning the head of the actuators, it moves up and down. I have now turned it "up" and thus the red marking appears on the actuator. Is it open now? I'm not quite sure from the marking.

No, of course I didn't take a photo beforehand... But I also trust our plumber to not have adjusted the flow at all... Or are there any calculations he should have regarding this?
