Lux TX9100E Smart Temp Programmable Thermostat
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.

Save Money and the Environment
Like all programmable thermostats, the TX9100E helps reduce energy consumption, but this efficient device takes savings a step further. 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.

5.0 out of 5 stars Easy install, full of features, October 22, 2009
Amazon Verified Purchase(What's this?)
This review is from: Lux TX9100E 7 Day Universal Programmable Thermostat (Tools & Hardware)
It took more time to remove the old thermostat than it did to install this new one. I did read the instructions carefully, but I did not look all the way through the packaging materials. I made my own wire labels from masking tape and carefully noted what each wire was connected to on the old thermostat. As I was getting the new thermostat out to install it, out pops a complete set of stick-on wire labels! Using those would have saved a few minutes.

The only thing that was not real clear was just when to attach the new thermostat to its wall-mounted base. Since I am using the optional battery backup mode, I found that I could sit in my recliner and program the thermostat, then click it into place on the wall mount. I don't use a lot of alternate programs ... just the same one each day. The "copy" option worked great. Just set up your first day, and copy it to the other days. Simple.

I have a heat pump with a second stage (very expensive to run) electric heat strip. My old thermostat would kick in that second stage whenever I clicked up the temperature setting a bit. This new thermostat lets you set just how far apart the setting for the heat pump and the second stage should be. Also, it has an "early recovery" mode that anticipates the morning "warmup" phase ahead of time, and it starts the phase early and gradually ... once again so that the second stage heat does not kick in unless it is really cold outside.

If there are any negatives, the backlight is not very bright. When you press any button you can see the display in the dark, but it isn't near as bright as a computer monitor or flat-screen tv. Still, if you are going to use this with the batteries as the sole source of power, this level of brightness would probably use minimal battery resources. If your wiring allows powering it directly from the furnace / heat pump, then it is too bad that there is not a brighter setting for the display.

5.0 out of 5 stars Lux TX9100E Thermostat, August 23, 2009
This review is from: Lux TX9100E 7 Day Universal Programmable Thermostat (Tools & Hardware)
This very versatile programmable thermostat is a great alternative to purchasing a more expensive Honeywell thermostat. This thermostat will readily wire up to any single stage or two-stage heat pump system - electric or gas; my unit is a Rheem all electric two-stage heat pump system. Lux shipped the unit promptly and well-packaged. All necessary mounting accessories and clearly-written instructions came with the unit. Installation was a breeze. I must note that if you are a do-it-yourself type, I strongly recommend that you contact Lux and/or your A/C-heater manufacturer to compare notes on which color wire goes to which terminal on your thermostat when connecting the wires. Each system's wiring codes are different, and thermostat makers add extra connection terminals to accommodate as many different systems as possible. For example, in my Rheem system, I have a brown "C" wire that is used as a common for the thermostat and a blue wire that is used to activate one of the heater controls. I connected the brown "C" wire to the "C" terminal and the blue wire to the "B" terminal of the thermostat. In other systems, there is no "C" wire and the blue wire is used as a common. In this particular case, if you were to connect the blue wire to the "B" terminal on your thermostat instead of connecting it to the "C" terminal, you could possibly damage your system. Once wired up correctly, the unit is very easy to program - it takes maybe 15 to 20 minutes to set up a 7-day routine that once set, can be left alone and never touched again and it will provide you with round-the-clock automatic temperature adjustments that will save you money and keep your home comfortable.

There is only one small negative to the Lux TX9100E thermostat. In some wiring applications, it may be necessary to insert a jumper wire between two specific terminals to correctly accommodate your particular system's requirements. Lux does not include this jumper wire in its package. You are required to make one yourself if your system requires it.

5.0 out of 5 stars Cut my electricity bill in half, June 30, 2009
This review is from: Lux TX9100E 7 Day Universal Programmable Thermostat (Tools & Hardware)
I went from a non-programmable thermostat to this LUX model. It has 4 time settings per day and is programmable for 7 individual days in both heating and cooling. That's 56 different times and modes that can be set. It's extremely flexible and is super easy to install. Having the unit adjust temperatures for the different zones in my house automatically during the day so that zones are adjusted for our usage has cut my electricity bill almost in half.
