Thermal balancing of underfloor heating - How to proceed?

Well, first the heating curve should now be turned down before adjusting the tscos. And this in such a way that the coldest room is found.

And please not like this... It’s still too warm outside. Best to wait until continuous heating is on. Then do the following: Turn all taco setters all the way up. Wait 24 hours. If it gets too warm everywhere = turn heating curve down, wait 24 hours Keep turning down the heating curve until the first room becomes too cold Then slightly throttle the (probably) too warm rooms Wait 24 hours If the cold room then becomes too warm again = heating curve down Repeat this until the desired temperature is no longer reached anywhere. Then turn the heating curve up a little again. This way you find the setting that still allows maximum flow with minimal heating curve. EDIT: DOCUMENT EVERY step. If you mess up, you at least know what happened. And note the result as well.

Are you kidding me? I say the same thing, just not as extensively..

PS here it was 2 degrees and ground frost last night, so that is enough for the thermal balancing.

But if you are as petty as joedreck, please first ensure that no solar heat gains disturb the measurement and deactivate all auxiliary heaters if present.

Thank you for the feedback. I will upload pictures tonight. So far, I have only removed the actuators and set the ERR to 0, as it is now unnecessary. Somehow, seeing the parts at 0 reassures me. I will wait a bit before doing the alignment. Since the HK is already at 2 out of 10, it is already very low. Should I therefore slightly increase it before starting the adjustments and then gradually adjust it? I will then turn the taco setter to the right and close it to the left?

It would be nice if you could reconsider your choice of words a bit. Besides, you didn’t write it exactly like that, but FIRST turn down the heating curve and THEN adjust the Tacos.
And yes, one should be meticulous there. Especially since the heat pump doesn’t run due to the currently still relatively high outside temperatures and thus distorts the results accordingly.
Of course, you can’t get reliable results if the fireplace is on in between, or, or.

Just a reaction to your statement.

You could have simply added that first all the tacos need to be opened.

And not "And so then please don’t..." Because it will end up exactly where 99% of homeowners do. The bathroom is the coldest room and gets 3l.

So now back to the topic.
