Hello,
if anyone happens to know a bit about this subject, I ask you to watch this short video of the display of the device named in the title.
[MEDIA=youtube]pp2ZunHAFpE[/MEDIA]
I have described something about it in the video text.
I am not familiar with this, but this behavior does not seem right to me. Why am I even dealing with this and making a video about it? Because the rooms heated with the underfloor heating barely get warm – but the plumber says "Everything is correct"...
Thanks in advance.

sounds like the mixer that is merrily going back and forth here. Do you have a buffer and a mixer?

Yes, exactly buffer and mixer. But the back and forth driving is not everything. It constantly switches off the pump (in the video at minute 2:13), so that for several minutes there is no flow in the underfloor heating. The whole thing happens in an endless loop, so the pump runs for 2 minutes, then not for 5 minutes.

can you set the pump to continuous operation?

To be honest, I don't know how. I haven't found anything like that in the menus on the display. And on the pump itself, there is only a control dial with meaningless symbols.
