Thermostat wiring diagram confirmation needed please!

Community Member

Hi! I need help with the wiring in my Nest thermostat 4th gen.

I have four cables:

Brown: 24v live (connected to C)

White: 24v neutral (connected to R)

Red: these are the cables from the gas boiler relay, if the close the circuit the boiler will start (connected to W and G)

Can someone please confirm my setup is correct? This is a picture of how I connected it:

No, that is wrong and the base isn't compatible with stranded wires.
