Does the “Nest thermostat’ not the E or 3rd generation. Just the one that is listed as a Nest Thermostat, has 2 AAA batteries in it work with a 2 wire gas fired steam boiler.

Hi Jsharpe,

Thanks for posting here in the community. To better check this, can you share with us the wiring set up of your existing Thermostat? Also, you might want to check this article to know about the Nest Thermostat compatibility.

Hi there,

Thanks for assisting, Emerson.

@Jsharpe, I wanted to follow up and see if you are still in need of any help. The Nest Thermostat (2020) often requires a C wire to work, though there are cases where it might not be needed but it works better if it does.

Best,

Mark
