Air-water heat pump current consumption and data

I don't really get it now either. The running pattern looks perfect, the pauses you mean are shutdown processes...

What surprises me more is why it stops heating at the end. Do you have any shutdown processes like p0_pause or something in the log?

Where do you see that he stops? One thing is defrost processes and at the other end he has reached the target return flow + hysteresis and switches off.

even if your modulating pump is way too big, it should never shut off at ~ -5 degrees. Hysteresis looks like 2k, right?

it is set to 1.5k.

Can you upload a .csv file here?

The breaks are really insanely short for such a long runtime. What causes the return flow to drop so quickly?

It's the same for me. I don't know why either... Within an hour, the return flow drops by 3K
