• Page 53: Understand temperature recovery feature Your thermostat comes with a feature called Adaptive Intelligent Recovery™, which eliminates all guesswork when setting your schedule. The thermostat determines how long it takes the furnace to warm your house or the air conditioner to cool it. Simply set your program schedule to the time you want the house to be at your comfort temperature. The thermostat turns on the heating or cooling at just the right time to reach your scheduled temperature. For example, if you want the temperature to be 70°F by 6:00 AM, set the Wake period for that time. The thermostat alerts you when the heating or cooling system is coming on before a scheduled time. It takes about a week for the thermostat to adjust to local weather, your schedule, and your home's construction. Each day, it adjusts the next day’s recovery start time accordingly.
