Nest Thermostat Compatibility

[NavidSalar]

Hi, 

I have a gas ducted heating system (Brivis Buffalo) with an Emerson manual controller. Was wondering if there's any compatible Nest thermostat on the market? My current controller has two stranded wires only (RH and W).

Thx

Hello NavidSalar, 

Thanks for reaching out to the Google Nest Community Forum. I understand you have questions about whether your wiring system is compatible with our Nest Thermostats. No worries; it’s a pleasure to guide you through. 

Based on the information you provided, it appears that your wiring configuration is compatible with most of our thermostat models. However, if you have a millivolt heating system, which is common in older homes, this system won’t be compatible with our Nest Thermostats. You can confirm this information and learn more about the different models by checking the Compatibility Checker. 

If you need more assistance, please feel free to ask here in this forum. 

Best regards, 

Daniel
