    Switching thermostats
    I have a newer standard American system, model 2tee3f37a1000aa, I'm switching the thermostats from the American standard to the new Honeywell smart WiFi. I understand that American standard uses the b wire instead of the c wire. There are no w1 and w2 on the new thermostat though. Please help.
