Measurement values natural cooling heat pump

Hi,
I would be interested in the normal measurement values for a heat pump with cooling function, from my feeling they should be lower for me. And shouldn’t there be a difference between flow and return? According to the heating engineer, the values are normal though. The pump is a Waterkotte A1+ with deep drilling.

Indoor temp: 21.7°C (Thermometer)
Outdoor temp: 29.8°C (Pump)
Flow: 21.9°C
Return: 21.9°C

Doesn't anyone have a Waterkotte and can share their values? I just have the feeling that something isn't quite right, but you can find almost nothing on the internet to use as a comparison. Here are the current values:

Current values:
Return flow target 18°C
Outside 21.9°C
Inside 24.3°
Supply/Return 24.5°C
Source in 11.1°C
Source out 11.3°C
Evaporator 20.5°C
Condenser 15.6°C
Suction line 29°C

hmm, no matter if it's the brine circuit or the heating circuit, there should definitely be a differential - as long as it's running. What (desired) indoor temperature have you set? To me, it looks like neither the brine circuit nor the water circuit are moving. That would also explain why the supply and return flow are very, very close to the indoor temperature. Because without a differential (in brine or water) you have no energy transfer. and thus zero cooling capacity.

There is movement in the heating circuit, all valves in the heating circuit distributor are open and flow is visible. Room temperature cannot be set directly, but the return flow setpoint is at 18°C. Sometimes there is a difference of 0.1°C between supply and return. According to the heating engineer, this is supposed to be normal, but I don't fully trust that.

then I would have said the brine circuit is standing. Because as I said, without a temperature difference there is no energy transfer

How can I tell if the brine circuit is stopped, I had the issue last year already with the heating engineer, had provided the measured values and got the response that everything is fine.
