ᐅ Air-to-Water Heat Pump: Current Consumption and Data

You can set the pump optimization to 5 minutes.
The heating element activates from -2°C (28°F), you can probably lower that further.
Set the efficiency pump minimum to 5 V.

Okay, I'll do that. Should I also switch pump optimization from no to yes? Or is just setting it to 5 minutes enough?

Yes, and 5 minutes

Is the thermal disinfection (legionella cycle) active? Was this a deliberate decision? Do you always flush all the pipes afterwards?

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

The temperature difference during standby confuses me. I hope it doesn’t escalate again. Let’s see how it looks after the next heating cycle.
The heat pump has been idle for almost 4 hours now and will probably remain off for another 2.5 hours.

Your return flow looks unusual. During a heating cycle, it starts normally at 2, then suddenly there is a sharp drop.

After that, your return temperature fluctuates significantly. Are you sure no error codes 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.

So, the question is: does the last heating cycle look unusual or is it okay?
