mine must be working differently then, I've used auto for the last six months set at 70. cool in the summer, warm in the winter. Although you seem to contradict yourself, if you are setting the temp and the heat is coming on, then it must know it's cold outside. I thought I had read here to use auto with the remote start for best results, or maybe I'm just misunderstanding you. Or more likely no one actually knows all the combinations that work, or half the trucks are one way and half the other, haha
