heatlink

Installation of Nest seems to have led to the destruction of my heating system. - Plumbers did some interesting wiring, connecting the power wires of the Nest thermostat to anything but T1 and T2 in the Heatlink, resulting in Nest H72 error. - Got plumbers back and they wired the thermostat into...

In the attached photos you can see the wiring and wiring diagram of the receiver I am looking to replace with my Nest Thermostat E Heatlink. My question is around the Common connection. As you can see I have a jumper from L to COM. Am I correct to believe that I should use L (brown wire) as...

I've had a quick look on the forum and have found similar but nothing I can see that's double cabled and with a fuse box. I think I've identified the black as C and grey as NO via the forum. Question is, what do I do with the wires from the boiler and fuse box. I'm assuming these do not go to...

Afternoon All, I've been trawling threads and Google for help. We've recently had an extension built and a new boiler installed. On asking the plumber to install the Heat Link he stated not his job and on asking the electrician he stated the same. This went on until electrician agreed. Any how...
