It doesn't imply that all could be present simultaneously.
Some combinations are mutually exclusive, and couldn't ever appear together.

Yes, there are several possible control units by Mitsubishi...
... and installers may also choose to use others anyway.

I did find some info.  At 10.30am today used was 39kw and provided was 116kw. 

weather compensation curve is set to 55c at -15c.   I have seen some on youtube set theirs lower than that. Wondering whether to try 45c at -15c? not altered it yet. 

Hot water was set to 50c, I've dropped it to 47c to see if that's better.

I cannot find any pump settings. 

You require the entire manual of course, not just these two pages.

It is a breach of Building Regulations Part-L that you do not have the required documentation and training to correctly operate your heat-pump system.

In essence, the Building Regulations come down to common sense.
It's astonishing that the scheme offered by your Council in conjunction with OVO Energy doesn't satisfy the legal requirements.

I had a problem finding the controller cos I was looking for a screen with buttons.  Not the tiny touch screen thing they almost hid on the sidewall. 

It's an Ecodan FTC7. I finally found a picture online of what the screen looks like but I do not know what the icons are. 

This is not my settings. This pic is clipped from the Mitsubishi website.  Can anyone explain the icons for me please?

I do know the guy that was here Friday increased the hot water temperature. It was only warm/hot before. Now we can't hold a hand under the tap cos it's too hot.  I need to change that.  Also I have heard it's possible to slightly lower pump speed for the radiators?  It's waking us up at night. 

as for cost:  Today we did one washer load, two dryer loads, showers, and normal laptop and TV use, and cooked one meal on the cookertop. Add the heatpump, with very little solar as it was a miserable day.  cost so far is £4.53   That is the highest it's been so far since install. No idea if that is good or bad. 

Is it correct that you get either a remote control for program (time/temperature) OR get to use Melcloud app.  Not both?  Is that true or bull? 

Thanks

Sorry.  I've had enough. 

Unfortunately your electrician is speaking out of the wrong orifice.  Weather compensation means altering the flow temperature up or down according to the outside temperature, and has absolutely nothing to do with freezing up.  

If you operate without weather compensation your heat pump will cost 15%+ more to run.   Although getting weather compensation 'spot on' can be a bit of a challenge, even a crude curve will significantly reduce costs (and make the house more comfortable because it reduces temperature swings).

If you are happy with this then obviously thats up to you, if not then you have the right to demand it, or an explanation why it is not applicable (which, presumably, should not be BS).  Here is an extract from MIS3005-I the MCS requirements for installers.  If they don't conform to these then MCS can take action including striking them off.  If you wish to pursue the matter then I suggest you show them this and ask them to write down the explanation, advising them that you intend to forward it to MCS.

Sorry.  I've had enough.
