Replacing Salus wireless thermostat with Nest

@stem I have always wondered why you need to wire in an earth when using the 12 power supply, have you any idea ?
I don't know, I've always wondered, but if I had to guess, I might think that it was something to do with the 12v power supply and that the transformer is earthed. If it wasn't and a fault occurred within the transformer maybe T1 or T2 would become live, as would the thermostat connected to it. Obviously no risk if the thermostat wasn't connected to them.........Or maybe it's there to provide protection in case someone inadvertently connects 230V to T1 or T2

My Salus has 230V coming to both the unit and to the boiler circuit board - (2 no 3C flex coming out of the spur) do i need 230V for the heat link and also to the boiler? there is a link between the common and Live in the boiler does this need to be removed also?

any comments appreciated
