I had a Heatmiser Neostat installed with my Ecodan.  I was told, I think, by Brendon that it was a simple on-off switch not suited to ASHP control. He advised stripping it out and installing Mitsubishi components.  I did exactly that.
Same for us.  Our Ecodan now runs on WC with all emitters fully open.  Neostats are now used for monitoring only.

@Morgan I'm still looking into this for you – the competent installers that are near you don't do "repair" work yet – they just want to full installs. I have, however, been given two names of installers that are very reputable – if/when they reply, I'll put them in touch with you.

That's very kind.  I've made contact via two websites here and had no reply so I suspect that they too are only interested in full installs.  Frustrating.

I suspect the reason may be that there is no grant that can be applied to repair work, so no opportunity to bump up the price. 🙄

@Morgan I've just sent you a DM with the details of @adrian-liddell from Busy Energy who comes highly recommended by other installers that we trust. I will let you contact Adrian and see if this is a project he can assist you with.
