• Your thermostat is a precision instrument. Please handle it with care.
• Turn off electricity to the appliance before installing or servicing thermostat or any part of the system.
Do not turn electricity back on until work is completed.
• Do not short (jumper) across electric terminals at control on furnace or air conditioner to test the
system. This will damage the thermostat and void your warranty.
• All wiring must conform to local codes and ordinances.
• This thermostat is designed for use with 24 volt and millivolt systems. The thermostat should be
limited to a maximum of 1.0 amps; higher amperage may cause damage to the thermostat. If you are
in doubt, call your utility company.

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.
TEMPORARY TEMPERATURE OVERRIDE
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.
•
•
•
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. OVERRIDE indicator will disappear
from display.
