Adaptive Intelligent Recovery™ Control Breakthrough Technology Senses Temperature More Like You Do Your Deluxe Programmable Thermostat is so smart, it’s almost human. • Your body perceives temperature from a variety of sources, not only from the air in the room, but also from your surroundings—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 might or might not reflect how hot or cold the room actually feels to a human being. • Your new thermostat reads both the temperature of the wall and 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 Optimum Comfort and Energy Savings Solution 70 F 60 SETPOINT TEMPERATURE ACTUAL TEMPERATURE 60 F SLEEP WAKE HEATING MODE THERMOSTAT USES THE SAME SCHEME TO RETURN TO LOWER COMFORT TEMPERAURE DURING THE COOLING SEASON. M15084 15 69-1400—1 DELUXE PROGRAMMABLE THERMOSTAT The Deluxe Programmable Thermostat is actually a small but powerful computer. When calculating the time to turn on your heating or cooling system, it considers (1) air temperature, (2) wall temperature, and (3) the time you want the comfort temperature established. • During the Adaptive Intelligent Recovery™ time, the thermostat increases the temperature setpoint from the energy savings to the comfort temperature. The equipment may shut off before reaching the comfort temperature to avoid going past the comfort temperature. This saves energy by avoiding cycling the equipment and overshooting the comfort temperature. The thermostat displays Recovery whenever the thermostat activates the Adaptive Intelligent Recovery™ feature. System Em Heat Recovery AM Mon Sleep Room Heat Fan Auto M14561 • This thermostat learns from experience. Each day it checks how closely it hit the recovery target and adjusts the next day recovery start time accordingly. • It typically takes four to eight days after installation for the thermostat to adjust to the local weather, your lifestyle, the construction of your home and your heating/ cooling system. The thermostat calculates the Leave/Return recovery separately from the Sleep/Wake recovery. [. . . ] THIS WARRANTY IS THE ONLY EXPRESS WARRANTY HONEYWELL MAKES ON THIS PRODUCT.
