RE: Ecodan Long Cycling and AA behaviour in one day.

Yes (and everything in-between lol). I was running a curve of 38C at -5 / 35C at +15, this would result in 4-5 cycles per hour during mild outside tem...

RE: Ecodan Long Cycling and AA behaviour in one day.

@derek-m What did Toyah once say, 'It's a mystery, I'm still searching for a clue..' 😀 . My system needs 40C+ flow temps when OAT is in the 12-15C r...

RE: Ecodan Long Cycling and AA behaviour in one day.

The curve was actually set for another experiment (that was working very well). It's another topic entirely so I won't go into detail here; but I 'inv...

RE: Ecodan Long Cycling and AA behaviour in one day.

I had a bit of time on my hands this afternoon (and it was raining) so decided to have a quick 'play' with AA mode again. OAT was 12C, and I set my WC...

RE: Ecodan Long Cycling and AA behaviour in one day.

That's in AA mode. General consensus (until now?) was that AA mode used the WC curve as a baseline and adapted from there - 37C was spot on where my c...

RE: Ecodan Long Cycling and AA behaviour in one day.

Hope you don't mind me joining this topic as well. Here's a chart with the AA 'thermo diff adjust' option turned OFF, OAT was mild (13C). The way I ...

RE: Ecodan cycling

Thanks Derek, very useful. I'm using the remote stat to turn the heating off at set temp +1 degree (at milder ambient temps). Set temp is 18C, so re...

RE: Smart meter installation – seamless or a potential nightmare?

It's not just 'old' devices - if you want a rather ironic example - best ask Mitsubishi why their Melcloud WiFi controller only supports 2.4Ghz. I t...

RE: Mitsubishi Ecodan & Raspberry Pi automations

I think I'm looking too hard, that's just the fixed flow temp default value so just a co-incidence. Just checked - my fixed flow was set at 36C.
