I program mine to come on 30 minutes before we awake and shut down 30 minutes Before we leave on weekdays. Then on 60 minutes before we normally get home and reduce 60 minutes before we go to bed. I usually adjust temperature change of 4-6 degrees differential only. I think if you do larger differential you need to adjust your start up times earlier. 3 units and house is always comfortable and my highest bill was just over $300 last year(Christmas and kids home,etc.). My previous house had one unit and was not insulated nearly as well and bill was on average more. Good move.
