Thanks to a large lighted display, patented Lux Speed Dial, and preprogrammed energy-saving schedule, the TX9100E is incredibly easy to use.
Multiple Programming Options
One of the easiest ways to reduce utility costs is to program your thermostat to fit your schedule. The TX9100E lets you create a different program for every day of the week, and you can enter four different time periods and temperature settings in a 24-hour period. And when you're away from home, you can use the vacation hold option to ensure that you're not paying to heat or cool an empty house.

Smart Recovery for Maximum Comfort
The TX9100E boasts Smart Recovery, which means the thermostat "learns" how long it takes for the furnace and air conditioner to reach programmed temperature settings. That way, the correct temperature is reached by the beginning of your programmed period.

User-Friendly Programming, Battery Monitor, and Keypad Lock
Thanks to a large lighted display, patented Lux Speed Dial, and a preprogrammed schedule developed to save energy and reduce costs, the TX9100E is incredibly easy to use. It even has a battery monitor that indicates when the battery power is running low.

The TX9100E also offers a programmable keypad lock and 10,000 different possible combinations to prevent unauthorized changes to the thermostat settings.

To maximize your home's energy efficiency, the TX9100E comes preprogrammed with a default heating and cooling schedule that's designed to save up to $500 in energy costs over a year, and can also help cut down on your carbon footprint. Because the TX9100E is 100% mercury free, you can be sure it's a safe and environmentally conscious choice for your home.
