Lennox s40 direct replacement for 10f81 iComfort?
Homeowner here with an old 10f81 that gave out today. Luckily my phone can still control the thermostat as I believe just the screen went out. I’m wondering if the new s40 that was released recently will be a direct plug and play replacement.
My concerns:
Will I have to rewire anything on the air handler?
I have a 2 zone system, will my second zone controller work with the s40?
I don’t want to have someone come out and quote me $2000+ for parts and labor for doing basically nothing.
Any feedback would be greatly appreciated!
I’m sure you guys are sick of hearing about Lennox and their made to break products.
