I have this on my nest, and one interesting feature, is it turns down the AC to a lower temp a few hours before the 'energy rush hour' so that your house doesn't get as warm. IE, I have it at 72 deg, a 'energy rush hour' is declared, the nest automatically turns my thermostat to 70 deg an hour or two before, then to 75 deg during the rush hour.
