Anyone monitoring a new R32 Ecodan?

Can anyone explain this mess…

I decided to see what would happen if I switched to WC in this mild weather. I was expecting cycling but why is it such a mess. Surely it should just warm up each cycle overshoot because it can’t get rid of the heat pause for a bit and repeat.
