So far so good by the way, the settings seem to have seen us through the worst of the weather. I've actually had to set the AI settings to -3 in the day and it's still done a sterling job.

Thanks, yes, I get that; the 1 degree correlation just tended to work out that way in terms of where I want the temperature and heading ranges to start and stop (and it also made explaining the example easier 😂)

As I understand it, the target flow temp should be adjusted, based on the outside temp? So if that's the case, wouldn't it have as linear effect, regardless of how cold it was? E.g. I have tried to set it so that it updates the target flow temp by ~1 degree for every degree the outside temp drops; LWT temp auto mode 25 45 Outdoor temp auto mode -4 16 So the difference of target flow temp between -4 and 1 should be 5 degrees lower? It's that correct or am I completely misunderstanding?

That's been very useful, thanks. I also caught up with the latter pays of that post as it seems I was a couple of months out of date! I'm currently experimenting and will let you know progress!

Hi, thanks for the replies. @ReedRichards I have previously read through that post, it's very informative. I keep hearing about weather compensation, but what settings would you say specifically relate to this? I have version 3.0.5.6 of the firmware... @Alwayslearning22... I agree. We originally were going to have a larger unit but the installer changed their mind at the last minute which admittedly did save a fair bit of money, so we can now use for increased energy costs of the less efficient pump! It's not too bad, it's only when the weather really drops the poor old girl has to really work to keep the house warm.

Hi, I've had an r32 5kw fitted for coming up to 2 years now. We love it, but I keep thinking it's not tuned optimally as trends to defrost every 50 mins or so in cold weather and also can easily chew through 70kwh of electricity per day on colder days which given today's prices hurts the wallet! I'm currently trying out the ai/auto modes and trying to optimise that. I've been going through the settings through the installation manual and also a semi handy youtube video ( ) There is one setting which I still don't write understand at the moment which is 'th on/off variable' as per https://www.manualslib.com/manual/1580071/Lg-Therma-V-Ahuw096a3.html?page=113 Can anyone explain the effect this will have at all? Thanks.
