CTA Aeroheat heat pump settings for improvement

Could it be related to the [Überstromventil]? During the last technician visit, he opened the valve quite a bit.

then you would probably also have the problem during defrosting in heating mode
can you provide a DTA?

Yes, link will be sent via PM

According to DTA, the defrost valve did not open. But it works in heating mode. A technician needs to take a look. Check with the manufacturer

Ok. Great. Thank you very much for the excellent analysis!

Are there any other points that should be configured differently on my heat pump so that it runs more efficiently?

I haven’t checked that quickly now
