Nibe F2040 12 kW with SMO 20 control fitted last August. Not sure it’s running correctly yet. What’s puzzling me is that the control monitoring always shows return flow temp higher than supply temp. And also showing info error messages about compressor limited by load and high condenser in, and high condenser out. Anyone have any experience of Nibe heat pumps or any suggestions?

I suspect there is an incorrect wiring connection. However not made any progress yet with the installer and I understand Nibe customer service will only address technical queries from installers.
