Can anyone tell me why the OP asked for information if they then cant be bothered to either get involved or even acknowledge that people are trying to help them.

They were last active this afternoon (on the site but they haven't posted/commented since the 15th), so they may have read the info and gone away to see if they can make use of it before coming back to either say thank you, or ask clarifying questions.

Not everybody's immediate priority will be following up on a forum thread straight away; maybe they have more pressing things needing attention or they have limited time or capacity and use that to try and act on the info, or maybe some emergency has cropped up, or (whatever).  I very much understand the annoyance when posters do not ever answer questions or acknowledge advice, especially when that advice takes a lot of effort to provide, but it's only been 4 days (and the question was posted at the weekend, maybe they don't have time during the week), no need for impatience.

Apologies for not replying sooner, we’ve had a catalogue of issues to deal with - home was built 5 years ago but has never been lived in so nothing has been used properly and there’s a long list of things that should have been dealt with in ‘snagging’ that never happened… we’ve already had to get a plumber and the sewer sump pump people out (multiple times for the pump) and are now waiting on electrician, oven repair and roofer - but mainly due to issues with Broadband which took nearly two weeks to get installed (and isn’t giving anything approaching quoted speeds 😡) and a patchy mobile signal… I’ve been able to read but not post (the phrase “insufficient bandwidth” is featuring heavily in my life atm, and currently applies as much to my mental state as our internet connection 🤦🏻‍♀️)

And no broadband and not-good-enough mobile signal has meant working from home hasn’t been possible, resulting in a 3 hour round trip commute…

Have you tried scanning the QR code on that unit in picture three?

I hadn’t, I hadn’t even clocked that there was a QR code to be honest, I’d been so focused on the screen 🤦🏻‍♀️ 

Thank you

Get in touch with the selling Estate Agent and ask them nicely to contact the Seller about this... Documentation (manuals) or even the name of the Installers/

Some info may be on the installed bits... and / or in the legal pack from your solicitors.

You need to look for makes and model numbers on any of the items...

Clear close up pics of the labels may help. 
Also the outdoor unit.

That Samsung bit has an installer? label with gas safe number that may help find the installer (or not based on that wen url).

That controller number DB68-03252a finds YouTube videos for a Samsung ASHP...  Start there?
Samsung will likely have full manuals available if you get the correct model numbers off the kit.

The thermostat Google image search found me this https://totaltiles.co.uk/touch-screen-underfloor-heating-thermostat.html
which has a manual available.

Seller has claimed not to have ever had any paperwork, manuals or instructions for anything, all through the buying process (which is one of the reasons it took so long - my daughter spent hours on the phone trying to track down various certificates he should have been able to produce, but couldn’t/wouldn’t, that our solicitor said were needed)

That link was very helpful, thank you 🙂

Thanks to you all
I passed on everything I learned from your responses and my son-in-law has managed to get the heating on. I think we still need to get someone in to check the set up as it’s entirely possible our very inexpert attempts to get things working might have inadvertently affected other things we don’t yet know about. The temperatures shown on the many room thermostats appears to be several degrees different to what is shown on the actual old-school thermometers we have scattered around the house, but we’ve been tweaking them up/down to establish more comfortable temperatures. 
 
Part of the problem was that when the electric tripped (first time we turned the oven on 🤦🏻‍♀️ oven repair person now added to our ‘to do’ list) the controller needed to be manually switched back on - the screen was lit up so we didn’t realise that it wasn’t on 😳

You’ve inherited a system that probably hasn’t been set up properly. Those wall controls are under-floor heating thermostats and the main controller is running a 50°C flow, which is far too high for underfloor. That usually means the zones are fighting each other and the heat pump is cycling instead of delivering steady heat. under-floor heating needs low temperatures and continuous operation, not radiator-style on/off control. The living room being cold suggests its loop isn’t getting enough flow. The quickest way forward is to get the under-floor heating manifold checked, open the loops, drop the flow temperature and run the system steadily. Once configured properly, an ASHP with UFH should be very comfortable.

No it isn't.

That is the DHW temperature!

Do not adjust anything based on this advice!!!!!

Your system probably works fine and doing what this person suggests is likely to mess it up!

Have you actually turned the heating on via the heat pump controller?

It was likely turned off over the summer.

Thank you for your warning stopping us from following the previous advice.

Indeed, it does seem that the controller was off - the agent advised us the day we moved in that the heating was on, so possibly this happened when the electrics tripped and we didn’t realise because the screen was lit up

   been reading this with interest as I'm in the learning process with our new ASHP. @ Jackieblack sounds like you've got you hands full.......
