nest 4th compatibility

[dhia1990]

is the 4th generation compatible with my thermostat

That appears to be a line-voltage thermostat which is not compatible with any of the Nest thermostats if you are located in the US/Canada market. If you are located in the UK/European market I don't think the Google Nest Thermostat is avaible.

Hello there,

I wanted to ensure that everything was covered here.

I appreciate your help here, @Patrick_Caezza.

@dhia1990, thanks for keeping up with our Nest Thermostat. High-voltage thermostats frequently have two to four thick wires coming out of them and are installed into the wall, which are not Nest compatible. Due to the high voltage they transport, high-voltage thermostats should only be installed or removed by professionals.

Please let us know if you have any other questions or concerns.

Regards,

Mark

thank you for asking ,the technician said that the thermostat output of my boiler are 230 v , so my nest isn't compatible with it .

Hello there,

Thanks for letting me know. In some cases, it’s possible that your system can be made Nest Thermostat-compatible by having them install a step-down transformer to 20–30 V to your system.

If there’s anything else I can help you with, please let me know.

excellent idea , and then which nest 2 ports should we use

Hi dhia1990,

If it is a heating-only system, connect the designated wires to the W/W1 terminal and the power wire to the R/Rh terminal at Nest. You can verify the use of these wires on your system's control board.

Thanks,

Mark
