ADAPTIVE INTELLIGENT

RECOVERY

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 thermo-

meters and standard thermostats sense only air temp-

erature, 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 calculat-

ing 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

control gradually changes the tempera-

ture 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
