TEMPERATURE OVERRIDE AND TEMPERATURE HOLD OPERATION These features let you change the current Set Temperature without changing the programs stored in your thermostat’s memory. This thermostat is “armchair programmable.” You can make any program or setting changes with the thermostat body off or on the wall thermostat base. The TX500 alternately displays the current time and the room temperature. It also displays the day of the week and the currently active control program that is controlling the temperature: MORN, DAY, EVE, or NIGHT. The set point temperature will appear in the right side of the display. In the winter, set the system switch to HEAT to control your heating system. In the summer, set the switch to COOL to control your air conditioner. In spring and fall or when windows are open, you can set the system switch OFF. Setting the FAN switch to AUTO automatically runs your system’s fan during heating and cooling. Setting the FAN switch to ON runs your system’s fan continuously even without heating or cooling. N O T TEMPORARY TEMPERATURE OVERRIDE MORN • Press UP/DOWN to change the current temperature setting. The OVERRIDE indicator appears on display. • The Override feature will be automatically canceled at the start of the next program period. • To cancel OVERRIDE prior to next program period press UP/DOWN until original set temperature appears.

Adjust temperature as desired with UP/DOWN. • Temperature setting will not change even after next program period begins. • To clear, press HOLD again. MO DAY HOLD ADVANCED FEATURES TEMPERATURE SWING A thermostat works by turning your heating or cooling system on and off whenever the room temperature varies a certain number of degrees from the set-point temperature. This variation is the “swing.” Your system should cycle on about 3 to 6 times per hour. A smaller swing number increases the number of cycles, so room temperature is more constant. A larger swing number decreases the number of cycles, to save energy in most cases. The dial must be in the RUN position to close the door. You can change any of the preset times and/or temperatures to suit your schedules for the weekday and weekend programs. Each day is divided into four periods: Morning, Day, Evening, and Night. Each period is programmed for HEAT and for COOL. A blank programming chart is provided below for you to record your temperature settings in that chart.
