CUSTOMIZING YOUR THERMOSTAT

Program Options Set-Up by Your Trane Dealer

Your Trane dealer has programmed your thermostat using the options checked below. For example, your thermostat displays temperatures in degrees Fahrenheit if the checkbox next to Fahrenheit (°F) is checked. Contact your Trane dealer to reprogram any of the options listed.

NOTE: If no options are checked, those listed in the first column are the factory settings on your thermostat.

Refer to the Definitions section for a description and comparison of Adaptive Intelligent Recovery™ Control (a Honeywell trademark) to Conventional recovery.

GETTING AROUND THE KEYBOARD

The keyboard is located behind the thermostat cover. Three frequently used keys are located next to the display (Increase temperature setting, Decrease temperature setting, and Information key). The thermostat displays important information such as day, time, schedule period, temperature, filter indicator, system and fan operation.

Emergency Heat

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).

When the heat pump requires servicing, the LED lights and the system automatically activates emergency heat. After contacting your service technician, clear the LED signal by moving the system switch to Em. Ht. then back to Heat or Auto.

Auxiliary Heat

The auxiliary heaters assist the heat pump under normal conditions when low outdoor temperature occurs. The auxiliary heaters may also operate while in the recovery mode to maintain comfort level. The thermostat displays “Aux. Ht. ” (see figure above) when the auxiliary heating equipment operates.

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 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.

	Room
Mon	In Recovery
Sleep
System	Fan
Heat	Auto
	M10344

In Recovery indication shown in example above.

	Pub. No. 22-5128-02
12	69-1216

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.

Changing Temperature Setting Until the Next Schedule Period

NOTE: This feature does not apply to Constant Temperature Setpoint Programming.

	Press Increase ▲ or Decrease ▼ until the desired

After selecting a temporary setting, display reads Temporary until canceled.

Example displays shows temporary heat setting of 70° at 6:00 AM.

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.
