Air-water heat pump current consumption and data

Can you measure the return flow to see if it really has 22 degrees? Then also measure the individual circuits to possibly find the short circuit.

However, I suspect that the cold return flow is coming from the now connected basement.

Here is the upper floor. Can you read this

measured directly at each radiator with the children's IR thermometer.

Now we are already at 36 degrees supply temperature? With a heat pump? What does the consumption look like now? It should be completely out of control

It is.

Here is the OG. Can you read this?

Hmm, the temperatures are already very high and also differ extremely from those of the heating system.

I would take the basement out again for now, otherwise it will easily take 2-3 days to heat it up completely.

Hello
What is the total volume flow at the moment? What are the settings of the heat pump? Please post the data from the CSV.

Was your heat pump still working perfectly on page 13 on Thursday? :D
