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.
