Installing Nest to Gas Boiler

[JimM]

Received gift.  Trying to connect to our gas boiler.  No AC, just heat.  Replacing old Honeywell mercury bulb thermostat with only two wires coming from wall (white and black).  Is the nest compatible and which holes do I insert the black and white wires?   Thanks

Hi JimM, 

Thanks for reaching out to the Google Nest Community. 

A few questions — what specific Nest thermostat do you have? Could you provide the make and model of your furnace? Also, could you provide a photo of the wires of your old thermostat so I can check on it?

You may also check our online Compatibility Checker or this link for more information about Nest thermostat compatibility: https://bit.ly/3qZ6OQ1\
