nest thermostat has different wiring diagram then shown on installation instructions

Because you can't rely on the wire colours alone to determine what they do, we can't really advise where you should connect them in Nest Thermostat. Do you have a photo of the wire layout with your previous thermostat?

Hello folks,

Thanks for assisting here, @David_K.

@HR57, to determine your systems' compatibility and their wiring configuration. Could you please share a photo of your previous thermostat's wiring?

We'll look forward to your response.

Regards,

Mark
