ABOUT ADAPTIVE INTELLIGENT
RECOVERY
TM
• People perceive temperature from a variety of
sources, not only from the air in the room, but
also from their surroundings—walls, windows
and furnishings.
• Human beings feel differences in temperature
as slight as two degrees Fahrenheit.
• Common household thermometers and standard
thermostats sense only air temperature, which
may or may not reflect how hot or cold the room
actually feels to a human being.
• This thermostat reads the temperature of the
wall as well as the air—and responds to tem-
perature changes as little as one degree Fahr-
enheit—so room temperature is more likely to
"feel right."

RECOVERY FROM ENERGY SAVINGS
on your furnace or air conditioner, it considers (1) air
temperature, (2) the temperature of the wall and (3)
when you want the comfort temperature established.
During Adaptive Intelligent Recovery
mostat increases the control temperature gradually
and turns the equipment on and off several times to
save energy by avoiding "overshooting" the comfort
temperature. See the current control temperature
anytime during recovery by pressing the PRESENT
SETTING key. On some models, both the SYSTEM
and ENERGY SAVING lights may be lit at the same
time during recovery.
This "smart" control learns from experience . Each
day it checks how closely it "hit the target" and
adjusts the recovery start time accordingly.
It typically takes four to eight days after installa-
tion for this thermostat to adjust to the weather, life
style, home construction and heating/cooling sys-
tem. The thermostat calculates the LEAVE/RETURN
recovery separately from the SLEEP/WAKE recovery.
