FEATURES YOU’LL WANT TO
KNOW MORE ABOUT
Comfort-R™ Comfort Enhancement
System
Comfort can best be described as the proper balance
of temperature and relative humidity, also known as
“your comfort index.” The greatest level of comfort is
achieved when the temperature and relative humidity
are in balance with your body. When the relative
humidity is low, you feel comfortable at a higher
temperature. Likewise, when the relative humidity is
high, you feel comfortable only at a lower temperature. However, if the relative humidity becomes too
high, then true comfort cannot be achieved at any
temperature.
The Comfort-R™ system is specifically designed to
enhance the moisture removal process of your air
conditioning system and to make the air drier. This
system is so unique, it received a patent from the U.S.
Patent Office. During times of high relative humidity,
as well as during mild weather, the Comfort-R system
increases the moisture removal ability of your airconditioning system. This results in a lower relative
humidity inside your home, which in turn, allows you
to feel more comfortable. The resulting lower relative
humidity also allows you to maintain the temperature
setting on your thermostat at a higher temperature.

Adaptive Intelligent Recovery Control
Your Thermostat Senses Temperature
More Like You Do
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 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.
these three things, Adaptive Intelligent Recovery™
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 In
Recovery whenever the thermostat activates Adaptive
Intelligent Recovery Control. So, In Recovery displays
during the recovery time from Sleep to Wake and from
Leave to Return.

The Deluxe Programmable Heat-Cool Thermostat acts
like a 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 to reach the comfort temperature. After considering

After installation or new schedule programming, your
thermostat learns from experience. How? 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.
The Optimum Comfort and
Energy Savings Solution
In this example, Adaptive Intelligent Recovery Control
starts to recover at 4:00 AM and reaches the comfort
temperature of 68° at 7:00 AM. Recovery time varies
with the starting temperature and the comfort temperature you choose.
Your new thermostat saves energy and keeps you
comfortable at the same time. 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
how to override the current programming mode or
hold the thermostat at a specific temperature while
you go on vacation. You can even program the
thermostat to return to normal scheduled programming on your last day of vacation so you don’t have to
worry about energy saving while you are gone or not
being comfortable when you return.

NEAT STUFF YOU’LL BE USING OFTEN
Setting Temporary Temperatures
If your thermostat is set for 7-Day or 24-Hour Operation, you can override the current schedule period and
change the temperature setting until the next schedule period, or change the temperature setting while you are
on vacation. You can also change the temperature setting indefinitely.

NOTE: If “▲” or “▼” appears under the temperature display, it means that both the heating and cooling
setpoints are being adjusted. Tapping the key changes both the heat and cool setpoints by one degree.
Press after the desired setpoint is reached to verify the setpoints.
NOTE: While in temporary operation, the thermostat uses conventional recovery for that period only. The
thermostat assumes you desire to maintain the temporary setting until the end of the period.
