ADAPTIVE INTELLIGENT RECOVERYTM CONTROL
Your new thermostat is so smart, it's almost human. You perceive temperature from a variety of sources, not only from the air in the room, but also from your surrounding walls, windows and furnishings. Humans feel differences in temperature as slight as two degrees Fahrenheit. Common household thermometers and standard thermostats sense only air temperature, which may not reflect how hot or cold the room actually feels to you. Your new thermostat reads both the temperature of the wall and in the air, and responds to temperature changes as little as one degree Fahrenheit, so room temperature is more likely to feel right to you and your family. The thermostat acts like a computer. When calculating the time to turn on your heating or cooling system, it considers air temperature, wall temperature, and the time you want to reach the comfort temperature. After considering these three things, Adaptive Intelligent

RecoveryTM control gradually changes the temperature from the energy savings setting to the comfort setting (for example, from a heating temperature of 62° at night to 70° in the morning). The system runs until the comfort temperature you choose is reached without overshooting the setting. This saves energy. How do you know when the system is in recovery? The thermostat displays "Recovery" whenever the thermostat activates Adaptive Intelligent RecoveryTM control. See Fig. 3. So, "Recovery" displays during the recovery time from Sleep to Wake and from Leave to Return.

After installation or new schedule programming, your thermostat learns from experience. Each day it checks how closely it hit the recovery target (for example, 70° at 6:00 AM) and adjusts the next day's recovery start time accordingly. After four to eight days, the thermostat has adjusted to local weather, your lifestyle, the construction of your home, and your heating and cooling system.
Optimum Comfort and Energy Savings
In Fig. 4, Adaptive Intelligent RecoveryTM control starts to recover at 5:00 AM and reaches the comfort temperature of 68° at 6:30 AM. Recovery time varies with the starting temperature and the comfort temperature you choose.

OPERATING YOUR THERMOSTAT
Your new thermostat saves energy and keeps you comfortable at the same time. By now you may be wondering how to program your thermostat and how to use some more time and energy-saving features. First, let's look at features you'll be using often, like setting the System and Fan keys, how to override the current programming mode or to hold the thermostat at a specific temperature while you go on vacation. You can even program the thermostat to return to your regular programming schedule on your last day of vacation so you are comfortable when you return and yet save energy while you are away.
