Nest Thermostat E UK - Relay Switching Voltage

[AndrewT11]

Please could you confirm whether the GB variant of the Nest Thermostat E supports mains voltage switching? There seems to be a lot of confusion over this.

The specification states that 
“High-voltage wires
If your thermostat is labeled 120V or 240V,
or has thick wires with wire nuts, or has
L1 and L2 terminal blocks, your system
is high voltage and isn’t compatible with
the Nest Thermostat”

However, I believe that this does not apply in Europe where many boilers use mains voltage switching, but I can’t find any information to support it.

Thanks

This should explain everything for the UK Nest E thermostat

That’s really useful. I am reassured that it will work, although I could not download the guide.

Why were Google Support unable to give me this??

Many thanks for your help.

Sadly Google support are not Nest anymore, and there answers your question!

Ever since Google took over Nest, it’s never been the same. Nest support had patience of saints and really knew their stuff, where Google sadly don’t.
