ᐅ Thermal Balancing of Underfloor Heating – How to Proceed?

Hello everyone.
A quick overview of the system.
Air-to-water heat pump Elco with underfloor heating, 9.93 kWh (kilowatt-hours) photovoltaic system, and central ventilation with heat recovery.

I have now removed the electric actuators for the hydraulic balancing and plan to run the system this way over the winter. I want to make the balancing adjustments using the "float valves." In which direction should they be turned to increase or decrease flow? Is there anything I should be aware of?
Currently, the settings are as they were for the hydraulic balancing.
The heating curve is set to 2 out of 10, and the reference outdoor temperature is set to 12°C (54°F).
So at the moment, heating only runs at night.

The delay time is set to 5 minutes. After this time window, the heating switches off if the temperature is above 12°C (54°F) and switches on if below 12°C (54°F). Would you recommend changing this value?

That won’t work. Please provide more information here and include photos of your heating system, manifolds, etc.

First of all, it is actually still too warm for any balancing.

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

Thirdly, simply remove the actuators first and wait for 3 to 4 days to see what happens. It is advisable to avoid adjusting anything during this time.

Interventions after a previous hydraulic balancing rarely involve more than +/-0.25 to 0.5 turns on the valves in the heating circuit distributor.

Well, first the heating curve should be turned down before adjusting the TSCs, making sure to identify the coldest room.

Please first of all record everything exactly as it is. It is best to create a list so that you document every single step, including its impact. Otherwise, things can get confusing.

Yes, first of all, don’t turn around anywhere. That only causes more confusion than you want.
