Hello,
I am interested in the typical measurement values for a heat pump with cooling function, as my values seem to be lower than expected. Shouldn't there be a difference between the supply and return temperatures? According to the heating engineer, the values are normal. The pump is a Waterkotte A1+ with deep drilling.
Indoor temperature: 21.7°C (thermometer)
Outdoor temperature: 29.8°C (pump)
Supply temperature: 21.9°C
Return temperature: 21.9°C

There should also be a few 3/2-way valves that switch back and forth between the modes.
