Thermal balancing of underfloor heating - How to proceed?

Hello everyone.
Briefly about the system.
Air-water heat pump Elco with underfloor heating, 9.93kWh photovoltaic system and KWR with central heat recovery.

I have now removed the electric actuators for the thermal balancing and want to set the system this way over the winter. I want to make the adjustment now via the "float valves". In which direction do these need to be turned for more or less flow? Do I need to pay attention to anything?
Currently, the settings are as they were made during the hydraulic balancing.
The heating curve is set to 2 out of 10 and the reference outside temperature to 12.
Currently, heating is only on at night.

The delay time is set to 5 minutes. After this time window, the heating turns off above 12 degrees and turns on below 12 degrees. Would you change this value?

this won't work, put more info in here and take photos of your heating system, distributors, etc.

Firstly, it is actually still far too warm for any sort of balancing.

Secondly, is what the balancing does, etc., known? T_im_Norden has a great explanation here. Have you already read it? https://www.hausbau-forum.de/threads/zentraler-raumtemperaturregler-fuer-err-der-fbh.35503/page-7#post-417304

Thirdly, first simply remove the actuators and wait, preferably 3-4 days, to see what actually happens and avoid turning anything anywhere.

The adjustments after a previously completed hydraulic balancing rarely involve larger ranges than +/-0.25-0.5 turns on the valves in the HKV.

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

Please first and foremost write down everything exactly as it is. It is best to create a list so that you have documented every single step including the effect. Otherwise, things get confusing.

Yes, first of all, don't turn around anywhere. You only create more confusion than you like.
