I'm getting ready to fit a new 3rd generation Nest thermostat (and Heatlink). When I've looked at the wiring centre it doesn't look like any wiring diagram. There are no wires to positions 1,2,3,4 & 5. There are connections to positions 6, 7, 8, 9 & 10 with permanent lives on 11 & 12. The issue...

Hi all.... I think it's possible to fit a Nest to my Vaillant 828 Turbomax boiler but I'm pretty confused about the whole thing really and there are so many different threads about doing it, I'm even more confused. I must say THIS thread is useful as it discusses fitting to a 824 boiler. Part...

Morning We've finally plumped for a nest persuaded by the slight Black Friday reduction. I'd read a few reviews beforehand and most advised they were easy enough to install (I suppose that is dependant on the installer!), I've had a quick look at the current set up, which has the mains switch...

Hi all, I'm planning to buy a nest v3 and self install if I can. V new existing system was installed in my house about 12 months ago. If it's possible I would wire the heatlink in the utility room where the programmable timer is currently. I am hoping this has the connections I need to do that...

Hi all :) I've just bought a NEST 3rd gen, and would like to use OpenTherm. The Nest 'doc' has me just using the OT terminals to control the boiler, but i've also read that it's a standard wiring (i'll replace the programmer) PLUS the OT. Does anyone have any experience with this? I've...
