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.
