yourself with your purchase before installing your new thermostat.

Then follow the installation procedures, one step at a time. This
will save you time and minimize the chance of damaging the

thermostat and the systems it controls. These instructions may

FEATURES

• The TX500 can be used with most 24

volt gas, oil or electric heating and air

conditioning systems or gas millivolt

heating systems. It cannot be used
with 120 volt heating systems or heat
pumps. Ask your dealer for other LUX
thermostats to control those systems.

• The TX500 is programmable. There

are four programming periods per day.
Each period can be programmed
separately.

• You can use the built-in time/

temperature programs, or alter

them to suit your schedule. The
TX500 provides separate programming
for weekdays and weekends — for both

heating and cooling. You can override the

programmed temperatures for as little as one
programming period or for an entire vacation.

• 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.
