Do the colors of the wires correspond to the letters on my new thermostat?

Last updated:

No, the terminal label letters do not stand for the color of wire that should be inserted. In fact, there is no code governing wire colors and thermostat connections. You should wire your thermostat according to the letters used to label the terminals, not the colors of the wires.
