Programming a Trane thermostat begins with selecting the comfort control you want to set. Set the clock or day schedule, and press the up and down buttons to select the weekday start time. Follow the same procedure to set the periods for leave, sleep, return and weekends.
To select the comfort control options, which include heating, cooling and auto, press the button under the system display on the lower part of the thermostat. Use the directional buttons to set a new temperature. Overriding the system keeps the temperature constant until the next programmed schedule. Alternatively, you can clear all schedules to operate the thermostat manually. The temperature remains at the desired set temperature. Select the fan to improve the air circulation of the home.
