Hi @clockworks. I was just suggesting the one hour MELCloud graph so it’s more detailed. I think @gary could see what I was driving at.... the actua...
Thanks for the description @clockworks, that gives a better picture of your setup. I’m not sure if I’m interpreting your graphs properly but it appe...
@clockworks The wireless controller will modulate the HP and reduce output as the HP approaches the target room temp- but only when in Auto Adapt m...
The first thing I have seen in your graphs is that opening the TRVs has allowed the emitters to offload more heat, making your home somewhat warmer. I...

That’s great to here…. im curious, If you’re putting a 2c drop on the flow temp what’s your room temperature drop at the end of the setback? (Of cou...
yes I’m already using weather compensation on our Mitsubishi but, as stated above, there isn’t a scheduled LWT setback option available. The trial I h...
Update: it looks like Daikin do exactly what I’m looking for in this post. I’ve just seen this video done by Heat Geek… over 2 years ago. It’s at 8m...
