Yes, I am aware of that.

However, the built-in controls are usually quite simple (even if someone hides a Smart in the name). They work simply on demand. During the day, few losses = little heating output. At night, exactly the opposite. But at some point, your screed is heated up enough that everything levels out and, if necessary, is also charged during the day. Now, during the transitional period, the whole system first has to "get going."

For the heat pump, there is actually no difference whether it is night or day (of course, this parameter still exists in the control). But if you want to meaningfully incorporate this parameter, then you really have to get involved yourself and build your own logic for it. Otherwise, it will just switch on and off rigidly.

At AI/Novelan, you can set a "Taganhebung", which is certainly possible with other manufacturers as well.

This also applies to heating times. During the day, increase the heating curve accordingly and lower it at night. However, whether this is worthwhile on average is questionable. Higher VLT naturally leads to a loss of efficiency, which must be compensated by the nighttime reduction.

Unfortunately, it's all Greek to me..... I can read the instructions 10 times or look something up in forums and only understand a fraction of it... if anything at all. You can ask me what my soil survey cost, which was 2 years ago now, what this or that classification cost, I don't have to look it up... I have it all in my head... but with the heat pump... no way ...

I had thought about programming it so that it only works during the day... I also entered something in a program with the times, but whether that is actually applied... at the beginning it used the heating rod, which I have already turned off... I then always saw the power peaks in the app of the photovoltaic system ...

That’s what I meant by [Taganhebung]

In September of this year I saved 30% compared to last year. [Klimakurve] according to Google almost identical. I am curious to see how the savings will look in the colder months now, whether it is transferable
