Nice, but one fatal flaw
Controlled Heat Well
Fairly easy to program
Good display
No Override Time Control
Best Uses
We bought and installed this best-buy thermostat, and it works well; has a large clear display; and was easy to program with its Copy operation; and has a very good price. But it has one big design flaw: when you override the temperature setting, there is no way to give or change the time that the override runs. If you boost the heat setting by 2 degrees, say, the override will be in effect until the next program change time, whether that's in 15 minutes or 15 hours -- there's no other choice. So to boost the setting by 2 degrees for 90 minutes, say, you have to set a kitchen timer for your 90 minutes, and then return to the t'stat to cancel the override manually. <br /><br />This is a great step backward from the 10-year-old Honeywell RTH8000 that we are replacing. When you override the setting on that unit, it immediately presents a clock time setting for how long to override before reverting to the program. You set the time for it to run right then, and forget it.<br /><br />The lack of this common-sense feature in the Lux unit is, to me, a great inconvenience. To my wife, it is a deal-breaker. So we will be discarding the Lux unit and replacing it, probably with the Honeywell RTH8500D. The Honeywell units seem to be the only ones that get this commonly-used feature right. A great shame.<br /><br />I would recommend this to a friend, but only with the caveat that they must be willing to live with the flawed override function.

Features good, loud hum bad
Backlight Hums
Best Uses
I purchased one of these and found out after installing that the unit had a high pitched hum when the backlight was on. I returned the unit for another and the second unit also had a humming noise, although it was slightly higher pitched and softer. I ended up returning it and getting a Honeywell.<br /><br />I had the unit installed for a couple weeks and it met my needs, except for the humming. It is possible some people might not notice it, or even be able to hear it, but for me it was a great annoyance. If you feel like going through the hassle, I'd recommend this if you can find a unit that doesn't hum. However, be prepared to return the unit if it bothers you too.

significantly inaccurate temp readings
Big display
Easy To Read Temp
Generally Large Buttons
Backlight time too short
Inaccurate temp reading
Noisy Backlight
Best Uses
We purchased this unit from Lowe's as our previous thermostat died. This unit was priced well and seems to have good features for the money.<br /><br />The NUMBER ONE problem is that the temperature reading of the room is off by approximately 4 degrees RIGHT OUT OF THE BOX. We had 4 other different thermometers placed in the immediate area overnight and they were checked often and the Lux unit was always 3-4 degrees too high. We even put 2 of them on the wall right next to the Lux to make sure it wasn't the wall affecting things. On rare instances the unit would get within 2 degrees too high but this was fleeting, and likely due to rounding more than anything (the other thermometers displayed temps to the 1/10th decimal place). This slight variance though only made me more concerned that the temperature variance was not even linear! Ugh.<br /><br />Yes, I know there is a calibration function in the menu. We set that to -4 and it was closer, but again the seemingly non-linearity issue kept showing up. So we decided to return the unit thinking it was defective. I swapped the unit for an identical model from a different Lowe's so as to not get one from a potentially entire bad batch. Put this unit in and it's exactly the same problem.<br /><br />While we could just set the calibration and call it a day and not worry about it, it bothers me that something like this can be so VERY far off. Thermistors in these devices should be pretty accurate and it doesn't give me a lot of faith when a company that makes things that regulate your house temperature can't even come close to properly calibrating the most basic component of the device. It's like a faucet that only outputs half-flow even though you have the valve open all the way, or an oven that is actually at 350 when you set it to 400 (yes I know this happens).<br /><br />Aside from the above the unit is okay. It's not amazing. The backlight is bright enough but makes an annoying high-pitched whine while it's lit. It only stays lit for about 10 seconds which isn't really long enough but not the end of the world. One other significant design issue though is that to turn on the backlight to read it at night you simply have to touch the screen, but doing so can select menus or change settings if you touch the wrong parts. So you have to know specifically _where_ to touch if you want to read it in the dark (while heading to the kitchen for a midnight snack) or risk changing things. They should make it so the first touch for the light doesn't select or something.<br /><br />But in the end, it's all about accuracy, and this unit fails to instill confidence.
