Air-water heat pump current consumption and data

Remove the fuse and see what happens afterwards.

I already did, just now. That's why the screenshot only shows a few minutes. that's still okay, at the top it's 20.2 degrees, at the bottom 22.8 degrees. It should have started normally just now.

Could it be that the heating curve for defrosting is too low for these subzero temperatures? I mean, we are very satisfied inside with 25/21/0. But maybe it is simply too cold for defrosting the outdoor unit at -10 and below.

Is the heating element deactivated?

Is the heating element deactivated?

Sure. Hot water has just started running, at least. I've set the heating curve to 26/21/0. I think that after defrosting, the heating operation will start immediately. Let’s see. I’m noticing that the -10 degrees is really challenging the heat pump; I’ve never seen this thing prepare hot water so slowly.

Heating operation has started. This also establishes the total house consumption for today. Yesterday it was 24.4 kWh and today it will be 29 kWh.

At least it is heating again. How is the AT with you?

We are already at -17.6° at 21:42, it will be interesting.
