Air-water heat pump current consumption and data

You can set the pump optimization to 5 minutes. The heating element is enabled from -2°C, you can probably go lower here. Efficiency pump min to 5 V.

Ok, I'll do that. Pump optimization also from no to yes? Or is the 5-minute setting enough?

Yes, and 5 minutes

Is the thermal disinfection (Legionella flush) active? Conscious decision? Do you then always flush all the pipes?

Is the thermal disinfection (Legionella cycle) active? Conscious decision? Do you always flush all lines then?

Everything set as suggested. What about the thermal disinfection? Is it on or off? Should it be on?

The spread in standby confuses me. Hope it doesn’t escalate again. Let’s see how it is after the next heating cycle.
Heat pump has been idle for almost 4 hours now and will probably not run for another 2.5 hours.

Your return flow looks strange. With one heating cycle, it starts normally; at the second, there is an immediate kink.

Then your return flow temperature fluctuates wildly. Are you sure that no errors are still active?

You have selected the disaster curves from the day before yesterday and yesterday morning. The last heating cycle is the one with the corrected flow rates.

Therefore the question is, is the last heating cycle noticeable or okay?
