@matt-drummer, apologies if you’ve covered this already - I can’t remember all the detail above! Have you enabled quiet mode?
I expected this to reduce performance, as in COP. However, all I’m observing is lower energy consumption & heat output. It’s enabled my 16kW LG to modulate down to around 750W rather than 1.5kW in normal running mode. I’ll just need to turn it off when it gets cold again.
It’s possible the Daikin is smarter than the LG and modulates down into this region automatically. The LG sadly doesn’t!
Edit - I see you have Anyone use Quiet Mode with Samsung ASHP to reduce cycling? - #4 by matt-drummer
Presumably means your unit is already using this range.
