BOTTOM LINE:
Took about 45 minutes from removing old unit to new installation and completing programming. It works great!
SYSTEM:
4 wire Gas heating and electric cooling.
OLD UNIT:
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.
TOTAL EXPERIENCE:
1 Week
REVIEW:
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. Touching the 'Menu' got me into the programming mode for the unit. I touched "SCROLL" to skip to the next feature, and "NEXT" for the next step in the feature programming. I do admit I took a few iterations to get used to the programming logic. Also 'YES' to accept settings is a little different from the colloquial "ENTER" we are used to in a computer literate world!
This unit is programmable for every day of the week. I, at most, need one setting for all week-days and one each for Sat and Sun. While programming the days, I noticed that they had a "COPY" function. I was sure that this was to copy my settings - every time I touched it, it went over to the next day. I thought that the data was being copied over and I did verify it after I completed my first iteration of programming. By the way, once you are in the programming mode, setting the start time for any period and/or setting the temperature is as simple as touching the time or temperature and using the up/down arrows. Could not be simpler!
I was fortunate that I had the program settings available from my old unit - once I went through a few iterations of errors (not using "YES" to accept settings!) the unit was programmed - Total time of 15 minutes
I spent another 10 minutes setting the 'Filter Usage' and 'Swing settings' and reviewing the 'Temperature Calibration' and 'Energy Usage' monitor. The Swing settings only went upto 2.5 degrees in 0.5 degree increments (One of the other reviewer found that it went upto 3.0 degrees???)
I did not see the 'Smart Recovery' option and thought that it might be a switch on the circuit board like my last unit. It was 1.30 in the morning and I did not feel like reading the instructions. I attached the TX9000TS and it kicked off instantly.
The instructions did have the following options that can be changed with the small slide switches towards the back of the main unit -- 12/24 hours time format, Smart Recovery, Degrees in C or F, and 2 or 5 minute interval between restarts.
OTHER REVIEWER'S CONCERNS
Some of the other reviewers have concerns that the unit does not automatically switch between heating and cooling to keep the temperature constant. This is done intentionally!
In the summer, our ideal temperature is 74 degrees. When we leave for work, our "DAY" period is set to 82 degrees so that the AC does not cool the home while we're out. In an auto switch between heating and cooling, the heat would take over and get the temperature to 82 degrees and maintain it - which is NOT the intent!! We do not want the AC to cool any below 82. I can, of course, see the gentleman's point if one spends 90% of their time at home and is OK with the associated heating/cooling cost.
PROS:
* TX9000TS is rated #1 by Consumer Reports
* Cheapest in its class for display size and features
* Very easy to program
* Love the LARGE display and the accuracy of the touch zones.
* Very nice Backlight and fantastic positioning of the backlight switch.
* Like the "CHANGE FILTER" feature. I used to use a Sharpie on the filter and then try to read the date through the grill
* Like the "Low Battery" alert.
* Power Usage also seems like a valuable feature...will find out in the near future! I did manage to find it by pressing menu and scrolling
CONS:
* Lux could have done a better job with the programming terminology and could have improved the user experience with regards to the programming. For e.g., if you had to program day and time, it continues to loop when you click "NEXT"...to exit the programming you need to use "MENU".
* Another feature I miss from my old Honeywell is the "RUN PROGRAM" button which when pressed would clear the "OVERRIDE" functions and run as per the program. The TX9000TS unit achieves this either by touching the temperature and using the arrow keys to bring the temperature to the programmed value, OR, by touching "HOLD" twice. Minor inconvenience.
* The tabs, on the top of the base plate, that hold this unit are very small and I am in constant fear of breaking them off. My old Honeywell had a very robust design.
CONCLUSION:
I do agree that the TX9000TS is not completely intuitive, but it is nowhere as unintuitive as others claim. I do like to play around with stuff that I get...if it were all super-intuitive and easy then it'd be no fun! ;o)
 Very good thermostat - but be careful! August 15, 2008

Florida gives heating/cooling systems a most arduous workout - and after high bills and uneven cooling with two thermostats I took Consumer Reports' advice, and bought the LUX. Good move. As always, Amazon delivered it on time and in fine shape.
Then came the off-with-old, on-with-the-new routine. Been there, done that many times, so I was prepared for minor surprises and major frustration. Nope. Despite the LUX manual's TINY print, I was able to get everything right the first time. Well, maybe not everything . . .
In this part of Florida, or "Flawed-duh!" as we love to label our fair state, there is no natural gas service. And it's a good think I dug into the manual before setting the new unit in place. Seems there is a very tiny "jumper" hidden away in the bowels of the thermostat. In "most" cases (but not all, apparently) you're supposed to take the jumper (a tiny bit of black plastic) off the "gas" pins, and slide it onto the "elect" pins. But not in all cases. . . . .hmm. Time to call the LUX guys.
My phone pal wasn't sure about the jumper, and had to look it up, but then came back to say that I did, indeed, have to move it.
Saying one smallish prayer, I picked at the jumper, to find that it did, indeed, slide easily off its pins. And onto the other set of pins, right next to it. Later, I'd find that I did it correctly. Whew!
That aside, the thermostat was quite frustrating to program, in that I had to remember what Scroll, Next, Yes, Exit, and Menu all meant. I managed to mix up Scroll and Next a dozen times before I got it right.
Once set up - it works like a charm! My AC unit cycles on-off less frequently, the house seems to stay at a stable temperature, and my work-at-home wife is a much happier camper. (read it: "worth every penny!")
I do have two very minor gripes: the hinges on top of the unit are very fragile - be careful when taking off the front cover! The other small irritant is that the "Menu" label on the front screen is half-hidden by the upper plastic case, and very tricky to activate.
Although some reviewers have given the LUX lower marks, I must say that (knock on wood) my unit works flawlessly - and is very easy for even my aged eyes to see in mid-night.
Excellent Thermostat...but pricey March 21, 2008

I've been using this thermostat for over a year now and it's a great thermostat. It's not intuitive, but once you practice setting it everythng's fine. One feature I like is it has a programmable "swing" which allows me to let the temperature in the house drop or increase up to three degrees before the heat/a-c kicks in...this saves a lot of energy and prevents "short cycling." Most thermostats that I've researched only allow a one degree deviation from the temperature I want and that's not very efficient in saving energy. I don't like Honeywell as I've had two of them fail; granted they were low end units, but not much fun when the temperature is sub-zero.
 Works but not happy with it. March 17, 2008

My system is a 4 wire electric heating and cooling system. It has a default jumper on the back for gas, slightly annoying. But once it was connected for the system it did do most of what it says. The temperature is easy to set for "override" but setting the time yourself (programmable) has not jumped out on how to do it. Yes I am sure it is in the manual, but something like this really should be pretty clear on screen how to set it up. But that aside and the reason I am not bothering to look into it is there are 2 major problems (at least for what I expect)
1. The system does not auto switch from Heat and Cool, the bottom left swtich when you open the panel has Cool-Off-Heat, seems to defeat some of the purpose behind a touch screen.
2. The box says it does power usage monitoring. I have tried scrolling through the options to find that and the closest thing I can find is the filter change that will let you know how many hours it ran. Not exactly what I would consider power usage monitoring.
I have seen other people with Honeywell and that is what I am getting next. The Honeywells look better and best I can tell, they are easier to work with.
Great thermostat... if large. June 12, 2008

I bought this thermostat to replace a programmable Honeywell unit that was the same price, and had many of the same features, but was inaccurate when it came to maintaining temperature. This Lux is easy to set-up, easy to take off the wall and replace the battery, and has many features the Honeywell did not have. I like the seven day programming, and the touch-screen. I do wish it displayed the room temperature and set temperature at the same time, though. Also, I am not fond of the switches that control heat or cool and fan mode, but it's a minor issue as those controls are not used often. Overall, it's a great thermostat.
