Hi thanks for your reply! I decided to take a punt so ordered it. Heatmiser sent me a battery tray for a different neostat so after complaining they did actually send the part I’d ordered. I am pleased to report it does work! I had to transplant the board into my old housing as they’ve changed the design of the little square nut for the bottom retaining screw for a nut moulded into the plastic with a round shape which clashes with the v1 stat itself. The rest of the housing is the same and the board slotted straight in. Been up and running successfully for over a week now. Might order a couple more for future use as I bet the others aren’t far behind. It’s interesting regarding the failure being related to heat - the one that failed is recessed into an upstairs stud wall and another I have of the same vintage downstairs is into a brick wall in a much cooler location! if the old board is of use before I chuck it please let me know.

just read this thread with interest. Have 2 x v1 neostat room stats, one of which went offline the other night. after switching the panels and backplates around I concluded one of the backplates has failed. I found that Heatmiser sell a V2 backplate psu as an individual part for £10 & postage although in the description it tells you only to buy it for v2 stats. Heatmiser tech support also confirmed this and pushed me towards buying a whole new v2 stat (which I don't want to do as they have a different colour backlight and won't match the UFH neostats that sit directly alongside, also seems excessively expensive when it's only the backplate that's failed). Earlier in this thread someone noted they had used v2 backplates with v1 stats and I've also seen an old ebay listing where someone sold a v1 stat/v2 backplate combo and said it was working fine. Can anyone confirm real life compatibility please? of course it suits Heatmiser to say it's not compatible because this will mean people can keep their v1 stats going longer using a £10 spare part 🙃
