Air-water heat pump current consumption and data

The purchasing strategy of many companies is, in my opinion, wrong. Actually, they would have to compare the purchase prices of their components with those of the service calls during the warranty period. In the case of a sensor, where the buyer might save 10 cents, there are often service calls costing 300-400 euros. And that for a part that costs them about 1-3 euros.... But I am also somewhat biased :p

As I said. Incentives and TCO including service. So you're at odds with the buyers? :p

But to get back to the topic: I'm already dreading all the problems that could come my way. If a small 3€ sensor torpedoes the entire heat pump control and my wife lynches me.

only with those who earn commission on the savings :p

I have certainty :cool:

Just out of frustration, at 23.7 degrees return flow with 12K spread to the supply flow, I took the sensor out of the sleeve and slammed it against the heat pump. Then I put it back into the return flow sleeve.

What can I say, immediately I saw a wondrous 27.5 degrees.

Where are the supply and return sensors located on your side? :eek: Can you just reach them like that? On my side, they are located in the heat pump outside. Without completely opening the housing and unscrewing what feels like 100 covers, I can’t get to them!

He is sitting on the return copper pipe in a welded sleeve on the hot water tower under an insulating cover.

However, the issue is only temporarily resolved. The sensor is still defective and will deviate.
