Or just buy it and fit it without the grant or any mcs rubbish? 7kW monobloc is sub £2k if you know where to look.

I’ll give it a try and report back. Currently drawing up a simple relay based circuit to enable to cooling call when any of the fan coils are switched to ‘fan only’ mode.

Do you know if dhw still has priority if I use the separate heating and cooling call inputs, instead of the a/c linkage input?

The midea are nearly always installed with either a plate or a llh for separation.

Perfecto…. He’s at installer show this week so I’m not bothering him with questions. So a/c linkage is a simple call for heat/cool with the ambient switching taking care of changing from heat to cool. The dedicated cooling call is just that and the same for heating call?

Hmm…. A dedicated call for cooling you say?

I’d like mine to have a little more options for cooling (dedicated cooling zone valve output for example, dedicated cooling call instead of a combined heat/cool call), but it does what we need

A good unit if I recall (I remember reading the manual from cover to cover)

Interesting thermostat, cheers. Shame my wife wouldn’t be able to use that - we run a nest for that very reason (peak ergonomics imho) Remind me again if you could be so kind what heat pump you’re using?

If we get another hot spell I’ll try setting the heat pump to 12 degrees and jumper out the call for heat (why oh why can’t we get heat/cool thermostats in the UK)… see how the fan coils work.

That’s an option for sure. Replace the bedroom rads with wall mount fan coils. I was thinking a separate unit and ducting would make pipe work easier as when I replumbed I didn’t consider cooling so made a few mistakes with pipe runs and lack of zoning. Not an issue with heating but certainly an issue if I want to cool, I’d need to valve off the existing fan coils which don’t have a condensate pan, and the rads. They’re all on the same zone.

This…. I raised the issue at installer show last year at the heat geek theatre talks. Because of the fact that we have the most expensive electricity in Europe (pretty much) , we’re scop chasing. If we could settle for an easy 2.8 and chuck em in like a boiler, it would make things much easier.

If only electricity was 5p/unit all the time - then we could actually get on with this decarbonisation without needing any complicated additional work. 50deg fixed flow temp, separation, on/off stats. Easy.

The r290 ones will give you the COP from the mobile app/wifi side. The older r410a 9kW and the slightly larger r32 10kW units, no.

FWIW, I didn’t use any. Out the ground with insulated twin, pex-copper adapters and copper onto the back of the unit.
