What flow temperatures are you currently running?

electrical power consumption at that time was, I think, 400 watts. I think I can also display the Hz frequency somewhere...

Crazy how low your heat pump modulates at the current outdoor temperature. Is the 400 watts just the compressor or the entire system?

I would say it's for the entire system.

Here and especially in the other forum, optimization is always taken to the extreme. :rolleyes:

It's also a bit of a hobby...

Can’t I set that on my heat pump? There is only heating curve slope and heating curve shift. Slope is set to 0.1 and shift to 0

How do you actually recognize the slope? With my brine-water heat pump, I can only set the heating curve with three values: 23 °C / 21 °C / 0 K

Heat pump has now been running for 52 hours, temperatures keep dropping here.

How do you most quickly track down a hydraulic short circuit (short heating circuit causing the return flow to rise too quickly)? I want to take another look at it over the weekend, as it’s supposed to get colder and snow. Since my heat pump modulates, it always adjusts the temperature difference, so I have mostly had a rather small temperature difference (~3K), with a few exceptions. I hope that when the system is more heavily loaded, it will then operate with a larger temperature difference (e.g., 5K), which would make an overly hot return flow more noticeable more quickly? Or is that nonsense?
