TRANE XT500C Deluxe Programmable Thermostats 

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 Recoveryª Control (a Honeywell trademark) to Conventional recovery.

NOTE: The XT300C and XT302C thermostats are manufactured for the Trane Company by Honeywell Inc. Specific features are unique to Trane and are only available on Trane models.

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 Òturn onÓ the electric heat section of the system by moving the system switch to the Em. Ht. position. The LED lights and the thermostat displays ÒEm. Ht.Ó when the system calls for emergency heating. The thermostat may also display ÒAux. Ht.Ó 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 recovery mode to maintain the comfort level. The thermostat displays ÒAux. Ht. Ó (see figure above) when the auxiliary heating equipment operates.

FEATURES YOU 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 Òyour comfort index.Ó 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-Rª 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 air-conditioning 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 the Temperature More As You Do
Your new thermostat is so smart, itÕs 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-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 these three things, Adaptive Intelligent Recoveryª 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.

In the Recovery indication shown in the example above. 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 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 the normally scheduled programming on

your last day of vacation so you donÕt have to worry about energy saving while you are gone or not being comfortable when you return. THE THERMOSTAT USES THE SAME SCHEME TO RETURN GRADUALLY TO A LOWER COMFORT TEMPERATURE DURING THE COOLING SEASON.

NEAT STUFF YOU 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

Conventional Recovery
Conventional recovery is an optional setting that allows you to choose the exact time your heating or cooling system comes on to start recovery, as opposed to Adaptive Intelligent Recovery™ Control. If your thermostat is set to conventional recovery, an displays continuously, as shown on the example display.

Conventional Recovery Modes

WAKE          You choose the time you want your heating or cooling system to start to reach your comfort temperature after the SLEEP period. Adjust this time to earlier when you know it will take longer for the system to reach your comfort temperature. Adjust this time to later when you know the SLEEP temperature is closer to your WAKE temperature.

LEAVE        You to choose the time you want your heating or cooling system to start an energy-saving mode while you are away (lower temperature during heating season, and higher temperature during cooling season) – follows the WAKE period.

RETURN     You choose the time you want your heating or cooling system to start to reach your comfort temperature after the energy-savings LEAVE period.

SLEEP You choose the time you want your heating or cooling system to start an energy-savings mode while you sleep-follows the RETURN period

Preprogrammed Schedule

The preprogrammed schedule consists of the four periods (Wake, Leave, Return and Sleep) and accompanying temperatures programmed into your thermostat at the factory. See Tables 1 and 4.

Period
One of the four times of the day (Wake, Leave, Return or Sleep) that you can program a setpoint or setpoint.

Setpoint
Setpoint is the temperature setting you select for a schedule or for a Hold. The set point can be either the heating temperature you set or the cooling temperature. Setpoint does not refer to actual room temperature or outdoor temperature.

System
The system refers to either the heating or cooling mechanics. For example, when the System is set to Heat, the heating mechanics operate according to the heating setpoint. The thermostat selects the System when set to Auto. Some installations allow you to turn the System off (neither heating nor cooling will operate).
