12. Thank you so much.

Yes, it is two stage. I am coming to regret that, since a lot of places don't want to work on it.

Unfortunately I'm in Texas. And I mean that "unfortunately" in more than one sense.

So if the wires in the wall match the thermostat it's good?

That great price on the Amana thermostat turned out to be something weird. The email bounced and the phone number just makes beeps. Oh well.
