I have a 2-stage AC system (AC only). It has the following wires - Rc, C, G, Y1, Y2. According to the Nest Compatibility Checker, the regular Nest Thermostat should work with this system. The problem is the regular Nest Thermostat does not have a Y2 terminal. How is it supposed to work? Which terminal do I use for Y2?

Replying to myself. I dug a little deeper and found that the *O/B terminal is programable and will function as the Y2 terminal in my situation.
Case closed.
