Adaptive Intelligent Recovery™ Control - Honeywell T8635L User Manual

ADAPTIVE INTELLIGENT
RECOVERY™ 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 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
Recovery™ 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 continuously until the comfort
temperature you choose is reached without over-
shooting 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 Recovery™ control. See
Fig. 3. So, "Recovery" displays during the recovery
time from Sleep to Wake and from Leave to Return.
