The Emergency Heat feature allows you to “turn on” the electric heat section of the system by moving the system switch to the Em. Ht. position. The LED lights and the thermostat displays “Em. Ht.” when the system calls for emergency heating. The thermostat may also display “Aux. Ht.” if the system calls for additional back-up heating (see figure to right).

FEATURES
•Worry-free programming.
• Comfort-R Comfort Enhancement Process—a unique American Standard feature.
• Adaptive Intelligent Recovery Control for comfort and energy savings.
•Wake, Leave, Return and Sleep at the comfort level you select.
• Customize the program schedule—program your own schedule to fit your needs.
• Continuous comfort and energy savings— adjust the schedule as often as you like.
•Temporary schedule override—set the thermostat higher or lower for the current program schedule.
•Vacation mode (1 to 255 days) for added comfort and energy savings. Set the temperature higher or lower for energy savings
while on vacation. At the same time, set the comfort level you want when you return.

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.
The Deluxe Programmable Heat Pump 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
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 Recov- ery whenever the thermostat activates Adaptive Intelligent Recovery Control. So, Recovery displays during the recovery time from Sleep to Wake and from Leave to Return.

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.
