Additionally, audible touch confirmation indicates that your choices are being registered, while snowflake and flame icons indicate cooling or heating mode. For further convenience, a filter-usage monitor allows you to set filter limits from zero to 720 hours of use, and a "replace" icon will appear when battery power is running low.

Took about 45 minutes from removing old unit to new installation and completing programming. It works great!

4 wire Gas heating and electric cooling.

Honeywell Electronic C9825 - bought in year 2000. Has weekday, weekend, 4 periods per day and adaptive recovery. Replaced as temperature override and 'Hold' features work erratically.

The TX9000TS is the 3rd electronic thermostat I've owned and is probably the most intuitive of them all. Lux has provided a generous sized display and a very responsive touch-screen. The back light is a pleasing blue. The unit is 3 parts - the main unit, a back plate where you connect the wires and an optional accent plate that provides a .75 inch border to provide a finished look.

I had read the earlier reviews on Amazon and had decided that I will not read the instructions prior to the install to determine how intuitive this system really was? The only exception I would allow myself was if the wiring was significantly different from my old unit - which it was not!

The setup was relatively simple. Removed the old unit and replaced it with the new back plate and accent bezel. No new holes to drill. The accent bezel is the closest piece to the wall and is held up by the back plate. I straightened the old wires, inserted into the corresponding clamp and tightened the screws - Total time of 15 minutes.

I inserted 2 new alkaline batteries (And NO, I did not use the recommended Duracell or Energizer!) and the unit came to life. I clicked on the time and it started beeping. I could see arrows on the right and intuitively touched them to set the time. Did the same to set the day.

I have been so pleased by this product. It was very easy to install. The large touchscreen and display size made programming a breeze. I didn't think it was possible to really like a thermostat, but this one is so easy to interface with and so attractive that I'm actually enjoying it a bit. The fact that it is a touchscreen is the best part--if I had to buy another thermostat and this model were not an option, I would definitely look for another that had a touchscreen. The unit is working flawlessly and keeping the house at a consistent temperature--much better than my old mercury thermostat.

Considering all the features of the TX9000TS, I think Lux offers this product at a very reasonable price. I have found that similar touchscreen thermostats from other companies cost much more.

Finally, I ordered this unit from a third-party seller on Amazon. On the screen there was a small defect in the coating of the touchscreen itself. I wasn't sure if the blip was supposed to be there, so I got in touch with Lux Customer Service. The response was almost immediate, and very helpful. They made every effort to understand what I was trying to describe, and once we determined that there was a problem, they agreed to send out a new one with a prepaid return envelope for my defective unit. I was so surprised at Lux's high level of customer service and their willingness to stand behind their product, since it is usually akin to pulling teeth in order to get problems like this resolved. As a result of the interaction I had with Lux, I would definitely favor their brand of thermostats in the future.

Really simple to Install with just a screwdriver. Wiring made simple by good instructions. The product itself comes with a size increase backplate to avoid having to redecorate if size does not correspond to old unit. Now onto the functions, really simple easy to program with smart copy function. Large display and numerals can be read from 10 feet away. Touch screen is a pleasure to use. Backlight is bright and clear and makes this unit an absolute dream do adjust in the night time or as you walk into the house.

I'm not what you would call a "do-it-yourselfer" for the most part. But we really needed digital thermostats, and I thought programmable thermostats would save us some money. The thermostats the builder installed when we bought our house seven years ago were not even digital. I just wish I'd changed them out sooner - I can't believe I waited so long!

We have two systems in our house, one in the attic to heat/cool the upstairs, and one in the basement to take care of downstairs, so I ordered two of these Lux thermostats. I would say that I spent an hour researching thermostats and also watching videos online that demonstrated how to install them, so when I got the package from Amazon I was prepared! I spent approximately 10 minutes installing each one, and most of that time was taking the old thermostats off and trudging up and down one or two flights of stairs to turn the circuits on and off! They were very easy to install and worked great right out of the box. The displays are large and easy to read, and the light function is very nice. Menus and settings are fairly intuitive and easy to understand.

I did have to adjust the heating/cooling schedules that come built in. The defaults are pretty "frugal" and you'll be very hot in the summer and cold in the winter if you use them! But it was very easy to program schedules the way we needed them, and now that I've used it with both AC and heat I'm very happy. Our last "late summer" electric bill was noticeably lower, and I can't wait to see how much lower our gas bills are this winter. I can already tell that we're using less energy, just based on the temperature in the house at various times of the day.

I was pretty intimidated at the thought of installing new thermostats, but this Lux product made it simple. Five stars!
