Real old school thermostat here. Wires are S, R5, and Y6. yes, that’s a mercury switch. Will it work with Nest thermostat?
please let me know if I can switch this beast. It’s heat only for an addition.
Thanks for reaching out. Could you share the make and model of your current thermostat? Also, what type of HVAC system do you have?
It's me again. I wanted to check back in to see if you have other questions and concerns. Feel free to let me know if you do.
