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?

Well, first the heating curve should be turned down before adjusting the thermostatic radiator valves. Make sure to find the coldest room first. And please don’t do it like this...
It’s still too warm outside. It’s best to wait until the heating runs continuously. Then do the following:
Turn all thermostatic radiator valves fully open. Wait 24 hours.
If it gets too warm everywhere = lower the heating curve, wait 24 hours.
Keep lowering the heating curve until the first room gets too cold.
Then slightly reduce the valves in the rooms that are probably too warm.
Wait 24 hours.
If the cold room becomes too warm again = lower the heating curve.
Repeat this until the desired temperature can no longer be reached anywhere. Then raise the heating curve slightly again.
This way, you find the setting that allows maximum flow with the lowest possible heating curve.
EDIT: Document EVERY step. If something goes wrong, at least you know what happened. Also record the results.
Thank you for the feedback. I will upload some pictures this evening. So far, I have only removed the actuators and set the ERR to 0, since it is now unnecessary. Somehow, seeing the values at zero gives me some reassurance.
I will wait a bit longer before doing the calibration. Since the heating circuit (HK) is already set to 2 out of 10, it is quite low. Should I slightly increase it before starting the adjustments and then gradually fine-tune it afterward?
For the Tacosetter valves, do I turn them to the right to open and to the left to close?

Are you joking? I'm basically saying the same thing, just not as extensively...
PS last night it was 2°C (36°F) with ground frost, so that’s enough for the thermal balancing. It would be appreciated if you could reconsider your choice of words. Also, you didn’t write it exactly like that; first lower the heating curve and THEN adjust the Tacos.
And yes, it pays to be precise here—especially since the heat pump does not run continuously due to the still relatively high outside temperatures, which distorts the results accordingly.
Likewise, reliable results cannot be obtained if the fireplace is used in the meantime, or similar factors.
Just a response to your statement.
You could have simply added that all the ducting must be opened first.
And not "And so please don’t..." because it will end up exactly where 99% of homeowners do. The bathroom is the coldest room and receives 3 liters (0.8 gallons).
Now, back to the topic.
