Easy install and programming!
We decided to go with this thermostat based on the price and functionality. When we received it, I was surprised on how easy it was to install and program. It has been working very well for us!

FIVE STARS
My live-in girlfriends seems to think that the house should be 30 degrees inside in the summer. The constant thermostat battle has just been won by me thanks to this awesome thermostat by LUX and it's lock-out feature. I am now in control of the temp and she can't over-ride it. It has many great features, was easy to install, and easier to program. Very clear instructions etc. I've recommended this to my dad and 4 or 5 friends and would recommend it to anyone.

No Support for Emergecy Heat
The product page is not clear, but this thermostat does not support emergency heat. I bought it, only to later find its not compatible with my Heat/Air Conditioning.

Does the job
Replaced an old mercury thermostat with one of these and I'm pleased with the results. Easy to install (took more time to disconnect the old one, than to install this one), easy to program. The one complaint I have is the delay before the unit comes on. I'm sure there is a good reason for it, but when its hot, I'd like to be able to turn the a/c on without waiting 2 minutes.

This is the Programmable Thermostat get!
Quick and simple to install. The kit includes a very good set of instructions for all skill levels. Includes a useful set of wire labels that eliminate confused wire connections. Has handy air filter replacement reminder system to help get maximum benefit. Thermostat easiy to programmable and operate. The device has saved a fair amount of expense on cost of electricity. Has AA battery-run program that keeps set up data through a power interruption. Has independent heat and cool programs. An excellent purchase.

Ordered 3!
I have to say this is the easiest thermostat I've ever owned and the display is big enough for my elderly parents to read with ease. I originally ordered one and later bought two more for gifts after I had some time to live with it. It's a little more expensive than some of the other options, but I am highly satisfied.

Solid thermostat for 1/2 the price
I'm giving this product five starts for the price. If it cost as much as most of its competitors with similar features, I'd probably give it four at most.
The thing that sold me on this thermostat, besides the much lower price tag, is the fact that it allows you to set your desired temperature sensitivity. Some other thermostats (e.g. Honeywell) have it pre-set to 0.5 degrees (I believe), and don't allow you to change it. That means you may save electricity, but you're killing your AC unit by constantly starting and stopping it. The default on this unit is 2 degrees, and I left it at that, but it is possible to change it.
I also like the the little knobs at the bottom of the thermostat (hidden by a slightly too-loose cover). They allow for old-fashioned fan/AC/heat setting. But the touch screen is nice too, and setting the temperature on it is what actually turns on the heater/AC, obviously.
The backlight is nice. I read you can make it stay on permanently, but I'm not sure if it's using the juice from the batteries if you do.
Speaking of batteries, they are not included for some reason... You'll need 2 AA's.
The installation was a total breeze. I didn't need instructions, and swapped out my 30 yr old analog for this baby in about 15 mins, including drilling and leveling.
I've noticed sometimes it thinks for a while before switching the AC on once I set the temperature. 2 minutes max. But more times than not it turns right on.
Needless to say I'm a happy customer. For half the price and more features than a comparable Honeywell, this is a great buy in my opinion.

Excellent product!
I've had this thermostat for nearly two years and have found it to be easy to program and use. I like that I can have it turn on and off in the morning and in the evening, so I save on energy costs during the day.

Lux Touchscreen Themostat, Terrible interface. Don't bother. Spend a little extra and get a honeywell.
What can I say.
It was between this and the Honeywell TH8320U1003 ($30 difference).
The Lux menu is NOT intuitive. If you choose this unit, please read the manual well (It's only 6 pages). [...]
It's very repetitive. Press Menu, Scroll, Select Set Review Programs, Choose Monday, Program Monday, Press Yes to accept and proceed and press up or down arrows to change temperature. Remember these things: Menu, Next, Scroll, Exit. Menu gets into the settings. Next switches between menu settings, Scroll allows you to browse through a specific setting, and Exit does what it implies.
You have to set MORNING, DAY, EVENING, NITE. There is no way to select 5 days and set them for the same thing. I would prefer to have the option available.
With a little practice, I could have gotten used to this thermostat, BUT the other members of the household would hate it.
This was the highest rated thermostat from Consumer Reports. I'm not sure why (I'll guess price). It works, I'll give you that, but it's so ANNOYING to program, I'm not sure how they managed not to start drinking halfway through. Seriously, I read the glowing reviews and was swayed, even with the few people who were dissenters. I should have listened and not wasted time. This unit might work as a thermostat, but the interface is TERRIBLE. If you are ok with that, peace be with you.
I returned this unit to amazon. Good riddance.
I instead ordered the Honeywell unit. I tried their virtual thermostat and was hooked. [...]
It's MUCH easier and intuitive.

Most affordable 7-day thermostat, with touch screen to boot!
Have had this thermostat for about 6 months and am loving it. It's reliable and easy to program. Great extra features, too, like the adjustable filter change reminder and the energy monitor. Program 4 cycles per day, and if you want to use the same programming on Tuesday as you did for Monday, you just hit the "copy" button and it automatically inputs those settings for you. No sitting there and entering the same 10 button sequence 5 times for Monday - Friday.
Highly recommend the WP9000TS Wallplate for Lux Products TX9000TS. Just added this for $2, free shipping, and it definitely enhances the asthetic appeal (if there is such a thing for a thermostat!). Buy it when you purchase the thermostat, so you don't have to take the thermostat off later to add the wall plate.
******************** UPDATE - JULY 6, 2010 ******************** Have started having problems with the thermostat about two weeks ago (Have had it since January 2010). Now, when I try to program it, after pressing the touchscreen 3-4 times (for example, while trying to program the current time), the screen resets (as in, all characters on the screen light up and stay lit, and I can't do anything else). The problem has persisted. The only thing the thermostat will now do is hold a set temperature, and even then, it resets after a day or two and does nothing until the batteries are pulled out for a few minutes.
Will let you know how the returns process goes. The owner's manual says it has a 3-year warranty instructs me to return it to Amazon; however, Amazon won't let me return it because it has been more than 90 days. Contacted Lux directly and we'll see what they say.

Used it to replace the faulty switch on my attic fan. So far , so Good. Working well!

Good idea, diffenential adjustment does not work.
I like the idea of these thermostats, we do not have central air and have four window units in our northern home, which we get by with. The thermostats (I have four of them) have a tempeture differential adjustment of 1 to 9 degrees. Guess what, it does not work on any of the four units, so with a 1 degree set (it dosen't change even when you put on 9 degrees) are snapping on and off all the time. This is not so much of a problem during the day, but at night in bedrooms it is a problem. To bad all these units have the flaw, they are a good idea. Rich, up north for the summer.

Handy for Basic Air Conditioner with Mechanical Controls
I bought the WIN100 Heating & Cooling Programmable Outlet Thermostat to use with my cheap window A/C that has manual controls. It won't work with units that have electronic controls unless the unit can be set up to come on when plugged in, because this thermostat effectively unplugs the device to turn it off and plugs it back in to turn it on. (For example, my big window air conditioner has electronic controls that go into standby when plugged in, waiting for input from the remote or front panel buttons, so this thermostat could not turn it on.)
There are 4 programs for weekend (Sat/Sun, no choice) and 4 other programs for weekdays (Mon-Fri, no choice). (You also set the time of day and day of the week, so you could deliberately set the day or time different from reality to accomodate special programming needs.) Each program is a temperature setpoint and time of day at which it becomes effective. There is also a temporary override that lets you set a different temperature, which remains in effect until the time of the next program, at which point the program takes over. Unfortunately, you have to flip open the cover on the front of the unit to access the override (and other controls), which requires unplugging the bulky plug of the air conditioner.
The unit can be (manually) set to operate either heating or cooling appliances. I have not yet tried a heater, so can't comment on how it works.
As long as your unit will come on when power is applied to its plug, this thermostat will control it nicely.

Happy Homebrewer
I use this to control the temperature in my fermentation box. Works really well to control heating pads in the winter and refrigeration in the summer. I saw another post about the temperature differential not working. That may be true, I can't really tell, but it doesn't affect my application.

Great product.
I have gas heat and central air and it was very easy to wire it up. Make sure you read the instructions first and most of all label the wires before taking them off old unit. It also was pretty fast setting up the schedule. Unit is up and running and so far so good.

East to Install and works great
You can really hear it click on/off, odd since I had assumed it was a solid state switch rather than a relay type of mechnanical one. Anyway, I'd had it over a year now and it still works great. Programming it and using it is easy as was the installation. Saving money with a programmable one is total BS though since prior to having one I would simply turn it off while I was out and turn it on when I get back. Now my home is more confortable when I get home but my electric bills are a bit higher.

Honeywell RTH7600B: Great Thermostat; Great Customer Service
I recently purchased this Honeywell 7-day programmable thermostat (RTH7600) from Amazon for about $15 less than it was offered at Lowe's Home Improvement. I decided to install it on Saturday while the kids napped.
Installation was super-easy (I've never installed a thermostat before). The packaging says it's a 15-minute install, and it was; though I didn't need to drill holes for the mount b/c this new thermostat fit on the holes drilled for my old thermostat I was replacing.
What stumped me was programming the thing (the thermostat is highly customizable), and my first thought was: "Why did I do this on a Saturday afternoon? Either no one will answer the 800 number, or I'll be in voicemail hell." I was wrong on both counts.
The customer service line WAS answered on a Saturday afternoon, and the CSR walked me through the programming process and asked me -- repeatedly -- if I understood everything or if I'd like him to go over it one more time. (It's actually not that difficult once you do it once). I was blown away by the help, and I'll definitely consider Honeywell for future purchases.
The thermostat has been up and running for a couple days now with no problems at all. (My favorite aspect of this 'stat is the fact that the backlighting is *really* bright.) Very easy to see/use at night. All around good experience. Highly recommended.

Definitely Worth the Purchase
Great purchase at a reduced price. I previously priced this product at over $119 retail price, and then at $100 after receiving a HVAC Technician's discount before finding it on Amazon for $85.
A programmable thermostat is great for homes when it is necessary for your A/C system to run while you're not home or asleep. Personally I have a pet, so I need for my home to remain cool while I'm at work or else I would just turn the system off until I come home. This product is great because I can set the temperature at a reasonable level without it constantly running, skyrocketing my electric bill, and having the house nice and cool right before I return home from work. The touch screen is a nice "touch", which lights up appropriately, even in the dark. The programming features allow you to set the temperature for several hours of the day and even raise or lower the temperature when you sleep, for everyday of the week.
Installation is not difficult, although it is very important to note and document the location of all wires on your old t-stat before removing them, so you can place them correspondingly on the new one. It is also important to know what type of system you have (heat pump, "straight cool", gas furnace, 1 stage, 2 stage...etc.) so you can program the t-stat to work with your system. Even as a HVAC Technician, I forgot to program the Honeywell to work with my heat pump system, so if you decide to do it yourself, remember that little piece of advice to save you some confusion as to why your system is running in heat instead of air conditioning.
If you are on the fence, I would encourage you to give it a try!
NOTE: If you decide installing the thermostat is too difficult for you, I would suggest NOT calling a A/C company unless you want to pay an exaggerated price because you did not buy it from them. For this type of thermostat companies may charge up to $400 or more for purchase and installation. Try talking to an individual A/C Technician that you feel comfortable with and explaining your problem and see if he or she would be interested in installing it on their own time, since it only takes about fifteen minutes to install. You would definitely come out spending less money working with an individual technician opposed to the A/C company itself should you require the assistance.

Great unit, easy to install, cheap in value high in quality!
I purchases this thermostat when they had a sale back a few months ago, and the unit is doing good. I just use the energy savings defaults and it keeps me cool enough during the summer months and I would recommend this unit to all.
The nice thing about the unit is you can remove it off the back plate so you can sit down and program the unit while sitting down.
8.5/10 = overall rating from me!

Great controller
This is the second one I've owned. Unfortunately, the first one died after about three years. But I liked the old one enough to buy an exact replacement. That's about as good an endorsement as I can think of.
The default program features an energy efficient schedule that keeps the house temps moderate during the day while you're gone and then turns on the AC/heat in time to make the house comfortable when you get home.
The installation is extremely simple.
The daily use isn't quite as simple if you want to override the set program. You can bump the temp up or down without too much trouble, but cancelling the override isn't quite as intuitive. Also, making your override "stick" doesn't always seem to work for us. For example, we don't usually sleep with the AC on unless it's too hot to open the windows. So in those cases, we close the windows and override the program to drop the temps. That's fine at bedtime, but then in the middle of the night when the program switches to the next time unit, the override expires and the house heats up. It's not impossible to prevent that, but it's nearly impossible for my pea-brain to remember how to do it without re-reading the manual.
All in all, this controller is great for my household and has saved my family a ton of $$$ during the hot seasons when we have to use the AC.

Very Large Thermostat.
I'm sure the functionality of this thermostat is excellent (I owned the older model of the same thermostat in my last house) however, I had to return it. I was so large 6"x5" that my wife and I felt it would become somewhat of an eyesore. Make sure you measure the area where you plan to put this thermostat as it is much larger than most.

Great Product
We've had programmable thermostats for years, so we are familiar with the features that we like and what we use. This one went a step further with the HOME mode. Older thermostats that we had needed to readjusted every time it went into the next time phase if it was not a desirable temperature while we were not at work. The filter alert is also great and being able to check hours that it's been running helps us see where we need to tweak our temperatures a bit to lower our usage. Very easy to use. Husband connected it in no time with little effort. Instructions are easy to follow. Would definitely buy again

Question : my amp gets too hot... i need a exterior fan for my amplifier.. !?
I have a 1400d amplifier and it can get hot.. and while im sitting at a light with the bass hitting hard the bass will clip out.. now i know its two issue that it can be..the amp not getting enough power and getting overheated, or plain ol' getting over heated with enough power or not..now its not even 5 inchs all around i dont belive for air to flow.. no circulation for air to move about really..where could i find a good fan cooler to keep my amp cool, the audio store suggested a fan thats kinda cylinder shaped.. if i get one wheres the best place to get it and install one
Answer:
Change your wires to 2 or 4 gauge, if you still want the fans here are some schematics:http://www.bcae1.com/coolfans.htm

Question : my soundstorm amp wont turn on?
my soundstorm amp wont turn on. i know that when the amp gets heated it cuts off until it cools down and then it comes back on. i have never had problems until now. i checked all the wires, the fuse, and capacitor but i still dont know what is wrong. the light does not come on at all on the amp but it shows that the capacitor has power. what could be wrong.
Answer:
If you have access to a multimeter, I'd check all the lines going into/out of the amp. With everything turned on, connect the ground of the multimeter to the car chassis (bare metal) and check for voltage on the positive (hot) lines, you should get a reading somewhere between 11-14 volts. If you don't get a reading, the line is not sending power. I'm assuming your main is getting power if the capacitor powers on, but what about the feed from the stereo?If all the positives are fine, hook the positive end of the multimeter to the main power for the amp, and hook the negative end to the amp ground. If you don't get a reading, the ground is bad/corroded. If you do get a reading, that means the amp is screwed up and will probably need servicing.You could do this with a 12 volt test light too, but a multimeter is only $20-$25 for a descent one at Home Depot, Menard's, WalMart, etc.Good luck!

Question : upgrading an electric circuit from 12v 20 amp to 24v 15 amp. Would the wires get less heated?
Hi, I have a circuit where I am using one (dc) car battery and sucking in 20 amps. Because the battery dies tooo quick, I want to add a battery and make it 24v and lower the amps a little.My question is that would my wires (note: just the wires I am using for conductivity) be running cooler or hotter than what they are right now? right now, the wires do get quit warm in the process.Thanks
Answer:
If you double the voltage the current will be cut in half. I don't know where you get 15 amps. Yes, the less current drawn the less heat will have to be dissipated in the conductor.

Question : Why do my home theater amp's protection circuits stay open even after cooling?
My amp shut off then returned the other day. But now NADA! Even after cooling! What now? Can it be permanently shut off due to heat in it's enclosure? Can an electronics tech open it and restore the protection circuits? I would then add a fan to the sealed wall unit the amp resides in. Can my expensive marantz SR-19 be saved?
Answer:
It seems common these days for a receiver to be damaged after the protection circuitry is triggered once or twice. Don't know if it's because damage has already been done before it triggered or if the protection circuitry itself can sometimes become damaged by being triggered.It can be repaired, but it will need to be repaired. I would guess somewhere in the neighborhood of $200.00. If it's aging, you may want to put the money towards a newer receiver instead. Never use anything but 8 ohm speakers with a receiver and never turn the volume up past the point where any clipping distortion is heard from the amp (amp runs out of clean power and music begins to sound "fuzzy"). The object of the game is to never trigger the protection circuitry because that's what seems to happen quite often if you do these days.
