Thanks Tim. That’s more really interesting and useful stuff to think about.
I know I should be able to get it into the My Heatpump app, I’ve been on the lookout for a decent set of instructions on how to do it. I did give it a try before Christmas, but I found that my EmonPi was only pushes new data when upload manually. It’s very much on my list and I totally appreciate it is might be a source of insight to others as well if I can get that to work!
After adding quiet mode this morning - it started up about 10:30 and has run without cycling at all, the compressor and FSP are also much more stable. The HeaterPower is rounded to the nearest KW - so I wouldn’t read too much into that - I summise it must be hovering around 3.5kw. I also think the flow/return gap has dropped a bit - I haven’t touched the diff.adjust yet, just waiting for it to cycle before I go onto the installer menu (which stops it running!)
That feels like quite an improvement.
Appreciate I haven’t looked at everything you’ve mentioned yet - so I will come back later. Thanks again!
