If my current thermostat requires batteries, does that mean I probably don't have a C-wire? From what I can tell though, it takes 3 AA batteries(that I have to change about every 6 months when they wear out) but I think all they do is power the memory that stores all the custom timing settings, I think the thermostat can still be adjusted up and down manually without active batteries, you just can't store any settings at all.
