Thank you everyone for help. It worked

Thanks, wasn't sure as followed instructions through but as wires are just numbered and Google instructions where asking for COM and No it was a bit confusing.

Does it matter which way round the two wires from Siemens thermostat go into Google Heatlink?

I have a Siemens RAA02 and want to install Google Nest Thermostat E with Heatlink Can I replace the room thermostat it has wires in 1 and 2 and earth, or do I have to take out controller. Really not sure what either wires are for and where they go into Google Heatlink. DSC_0876 by Ben...
