8:30 PM set to 67. Off at 6:30 AM. Cools BR down nice for sleeping. It doesn't run that much after it gets cool. I put it in usually in May when it starts not cooling off in the evening. I'm not sure if it's saving much money but I think it does. I used to turn the whole house down at night for better sleeping. Only cooling one room has to be more economical than the whole house. If I ever build another house it'll have mini splits in every bedroom.
Whole house unit runs a lot from about mid morning until after dark on these 100 degree days. July is the most it's ever run, by a long ways, according to my fancy thermostat I've had for a couple of years.
