How to tell if underfloor heating is running - ERR still without thermostat cover

136 kW heat for the heating, 67 kW heat for the hot water.

Is the screed program probably included?

How much electricity did the heat pump draw?

By the way, the heat meter should be able to display the flow temperature, at least according to the manual.

Attached is the status regarding electricity consumption.

Also attached are pictures from the professional area of the heating system. I couldn't set the heating as I had thought. For example: at 0 degrees 28 degrees and at -10 degrees 32 degrees. However, I could only set the flow temperature within the min and max range of 20 to 45 degrees. I have now set 32 degrees as max in all zones. Who can tell me that they are not already running at 0 degrees?

What is the deal with the 3 zones anyway? This is not clear from the manual.

What do you think of the GREEN mode? This avoids the use of the heating rod.

The heating curve is set to 0.6. It can be adjusted from 0.2 to a maximum of 1.0. What should I set it to?

The type of temperature control is 3 out of 4. What is that about?

The heating curve is set to 0.6. It can be adjusted from 0.2 to 1.0 at most. What should I set it to?

Set it to 0.2

if that turns out to be too little in winter, set it to 0.4. (Or even higher if the system can't reach the temperatures)

Who tells me that they aren’t already running at 0 degrees?

That is what the heating curve is for. It prevents temperatures from being raised higher than specified by the curve. You can also set 100°C (of course you don’t do that and it’s a very, very simple example and in reality everything is a bit more complex) but if the heating curve says temperatures must not exceed 45°C, then they won’t go above that.

When your electricity meter has recorded the complete electricity for the 8 weeks of operation, the heating system's coefficient of performance is good. Then you would have generated approximately 270 kW of heat with 35.37 kW.

If your electricity meter counted the complete electricity for the 8 weeks of operation, the heating system's coefficient of performance is good. Then you would have produced about 270 kW of heat with 35.37 kW.

I'm not quite sure if you mean it seriously or not? Could something be wrong here? The conversion should be about x4 for the annual performance factor, right? This doesn't fit at all here.

The annual performance factor (Jahresarbeitszahl) is actually not a constant value, but depends, for example, on the ambient temperature.

When it is warm, an air-to-water heat pump requires less energy to generate heat; when it is cold, it requires more.

Calculated over the year, this results in the average referred to as the annual performance factor.
