Is there some room temperature regulation? If these regulators are set to a temperature which is about the room temperature, you might get quite some frequent switching on/off while the temperature goes above and below this setting. This could also be influenced by the heat pumps activity and the changing air flow.
If you look at the forward temperature/framledningstemp. curve, is it rather smooth with some defrost drops or is it quite some zig-zag pattern?
Or is there some filtering (e.g. over 24h) of the outer temperature active, which might permit additional power during some nights and not during the others depending on the add power stop temperature?
There are room regulators on the bottom floor where I can set wished temperature. Top floor is radiators with scale 1-9.
Room regulators bottom floor set to 21C and radiators all open on max 9.
Posting images from today and this weeks framledningstemperatur. (Past night was raise to 60C water tank every 7 days).
How do I check filtering time and setting?
Thanks
