Automatically turn off AC if it's cool outside

If it is warm inside your house but cool outside, then you are wasting energy if the AC is running. Use this to stop it, and open your windows instead! This will set your target temperature to a higher value (set it high enough that you know it will stop cooling) when the temperature outside your house drops to a temperature you specify.
