Nest Gen 1

Hi guys

I have a Nest thermostat Gen 1 (Heating only) and a vokera Compact He Boiler that i would like to connect it too. I have it all set up apart from connected to the Boiler as im not sure where to wire it too. I have a pic of the back of the clock and the heat link . I have been told that i can do it myself as i am not touching the gas itself ?. Any help or advice would be great.

Think i have it sussed . Can someone confirm if i disconnect 1 and 2 and connect the heat link 2 and 3 (Relay) that should be it sorted ?. What about 4 and 5 what does the M stand for do i leave these connected ?

Yes that’s right and the M wires in 4&5 can also be disconnected, they are supplying power to the timer motor which will no longer be required.
