If you cycle, you won't get rid of the heat. ERR active? How much power does the heat pump have? If it only runs for 8 hours, it has to cool down for 16 hours to catch up, so you shouldn't be surprised about the flow temperature.

I currently have the "problem" as well. The heat pump runs for 8 hours, then pauses for 8 hours, and so on. It would be better to get the unit running continuously. But my system is slightly oversized and probably can't modulate down that far. The question is, could you trick it somehow? That would definitely increase efficiency by a few percentage points. Although I don't understand exactly how it modulates. Because when it runs, it goes full throttle at 8 kW. But it could also run at 5 kW. I haven't figured out yet when it draws how much.

That depends, among other things, on the set hysteresis. At the beginning, it always goes full power first, and then when it reaches the upper hysteresis range, it throttles down. But 8 kW is already massive.
