Example of thermostat display. 9 69-1332--4 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 10 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 continuously 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. "Recovery" displays during the recovery time from Sleep to Wake and from Leave to Return. System Em Heat Recovery AM Fan Mon Sleep Room Heat Auto M14561 Fig. 3. Example of "Recovery" indication. 69-1332--4 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. 11 69-1332--4 At 7:00 AM System Operating in Comfort Mode System Heat AM At 6:00 AM Recovery Continues Fan Mon Wake Room Auto TEMPERATURE System Heat Recovery AM At 5:00 AM Recovery Continues System Heat Fan Mon Sleep Room Auto Recovery AM 1 Fan At 4:00 AM Recovery Begins System Heat Mon Sleep Room Auto Recovery AM Fan Mon Sleep Room Auto ENERGY SAVINGS PERIOD RECOVERY FROM ENERGY SAVINGS TIME COMFORT PERIOD THE THERMOSTAT USES THE SAME SCHEME TO RETURN GRADUALLY TO LOWER COMFORT TEMPERATURE DURING THE COOLING SEASON. 1 IF In Recovery IS DISPLAYED, PRESS TO SEE THE COMFORT SETPOINT.

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. Setting System and Fan Keys Use the System and Fan keys to change the system and fan settings. The fan settings can be set for each schedule period individually. The system selection is for all the schedule periods. CAUTION Equipment Damage Hazard. Can cause permanent damage to the compressor or other equipment. To avoid possible compressor damage, allow the compressor to remain off for five minutes before restarting. To avoid possible equipment damage, do not operate cooling when the outside temperature is below 50°F (10°C). See equipment manufacturer instructions. 13 69-1332--4 Setting the System Key Press the System key until the desired system (Heat, Off, Cool, or Auto) displays. System HEAT PUMP Em.Ht: Emergency heat is controlled as stage 1 heat. Cooling system is off. Compressor is de-energized. (Available only with multistage heat pump.) Heat: The thermostat controls the heating. Off: Both the heating and cooling are off. Cool: The thermostat controls the cooling.
