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.
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.
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.
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 temperature setpoint displays.
While selecting a temporary setting, only the setpoint displays.The temporary temperature setting you select displays for approximately 3 seconds. The display reads Temporary until the next period begins, or you cancel the Hold.
To cancel the Hold before the designated time, press Run Program.
After selecting a temporary setting, the display reads Temporary until canceled. Example displays show a 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.
NOTE: This feature does not apply to Constant Temperature Setpoint Programming. NOTE: The current time does not display while in this mode.
NOTE: The display changes from the setpoint to the room temperature after approximately 3 seconds.
To cancel the Hold, press Run Program.
Vacation Mode
NOTE: This feature does not apply to Constant Temperature Setpoint Programming.
To cancel the Hold before the designated time, press Run Program.
The Information key provides information at your fingertips. The sequence of key presses is as follows:
If the filter status is expired (refer to Filter Indication section), the sequence of key
Displaying Outdoor Temperature
NOTE: If the filter status is expired, press
Displaying Current Settings
Press
NOTE: Without outdoor temp. sensor, press
NOTE: If the filter status is expired, press
Filter Indication
Your thermostat monitors the time the fan is running and lets you know when to replace the filter, based on the number of fan run-time days you select. Upon expiration, the thermostat displays Filter, and the backlight flashes during the Wake and Return modes. To temporarily cancel the flashing display, press
Your thermostat comes preset to the 30-day setting. To change this setting, or reset it after filter expiration, follow these instructions:
IMPORTANT
To track the time the fan is running, you must select a setting other than 0. If the setting is 0 days, the display will always show Ò0 Days; 0 SettingÓ when Filter is pressed.
Clock
Setting Current Day and Time
IMPORTANT
Always press the keys with your fingertip or a similar blunt tool. Sharp instruments like pens and pencil points will damage the keyboard. On initial power up or after an extended power loss, 1:00 PM flashes on the display until a key is pressed.
The system’s default setting is Heat and the fan’s default setting is Auto. Use the System and Fan keys to change the settings. The fan settings can be set for each scheduled period individually. The system selection is for all the scheduled periods.
7-Day Preprogrammed Schedule
If your thermostat is set for 7-Day Operation, follow the steps below. Otherwise, refer to 24-Hour Program and Operation, or Constant Temperature Setpoint Programming.

Before starting the programming procedure, use Tables 2 and 3 to organize your schedule. The preprogrammed schedule is shown in Table 1. Four time periods are available for each day of the week Ð WAKE, LEAVE, RETURN, and SLEEP
A Word About Power Outages
DonÕt worry! Your thermostat retains the schedule (preprogrammed or your own) for the life of the product. The clock and day information is retained for a minimum of ten minutes during a power outage. After a longer power outage, the current time and day may need to be set (1:00 PM flashes on the display), but the schedule is retained.

To modify the preprogrammed schedule, start by programming the Wake time and temperature, and fan operation for any one day:
NOTE: This schedule follows the current day and time you set in the section Setting Current Day and Time and the Heat or Cool setting and Fan setting you selected in the section Setting System and Fan.
NOTE: The copy feature applies only to 7-Day Operation. The thermostat must be in program mode to use the copy feature. Go to step 2 if the thermostat is already in the program mode (Set Program displays in the upper left corner).
Suppose you want to skip a scheduled period or periods for a particular day because you donÕt need them. For example, if Saturday is a day you normally stay at home from school or work, you can clear the Leave and Return periods for this day and keep the Wake and Sleep periods. You can always reprogram the periods later.
NOTE: The clear feature applies to 7-Day and 24-Hour Operations. The thermostat must be in program mode to use the clear feature. Go to step 2 if the thermostat is already in the program mode (Set Program displays in the upper left corner).
24-Hour Program and Operation
24-Hour Operation is the same as 7-Day Operation except the same program repeats itself each day. Monday through Sunday follows the same exact schedule (four periods and up to eight temperatures).
24-Hour Preprogrammed Schedule
If your thermostat is set for 24-Hour Operation, follow the steps below. Otherwise, refer to 7-Day Program and Operation, or Constant Temperature Setpoint Programming.

Adaptive Intelligent Recovery™ Control
Adaptive Intelligent Recovery™ Control is the factory default setting that allows you to choose the exact time the room reaches your comfort temperature, as opposed to conventional recovery. Adaptive Intelligent Recovery™ Modes
WAKE You choose the exact time the room reaches your comfort temperature after the SLEEP period.
LEAVE You to choose the time you want your heating or cooling system to start an energy-savings mode while you are away (lower temperature during the heating season, and higher temperature during the cooling season) – follows the WAKE period.
RETURN You choose the exact time the room reaches your comfort temperature after the energy-saving LEAVE period.
SLEEP You choose the time you want your heating or cooling system to start an energy-savings mode while you sleep-follow the RETURN 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.
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
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).
