Customer Questions & Answers

Battery replacement location on device

I am a new tenant here and screen says low battery.
Asked by: Irish
The unit has two openings. The first flap door is to access more controls. The second opening splits the unit in half and the battery compartment is in the first half now held in your hand. Change the batteries and replace your steps. However, as a tenant I recommend that you contact the owner/manager and let them do it.

Does this model have the adjustable swing value?

Asked by: warneman
Yes it does. From 1 to 10. The lower the number the more frequent the AC will cycle per hour.

I am interested in adjusting the cycle to give more timing for the on and off setting. The older mechanical thermostat that we have is on and off about every 10 minutes. Does this Lux Thermostat have the feature?
Asked by: Ralph
Yes, if you are talking about the cycling of the AC unit during an hour; this is the swing value and it is adjustable from 1-10. Go into the program menu and follow the steps.

I like the fact that I can adjust the temperature span. I wish the temperature readings would show tenths of a degree. During set up, I used another thermometer that displayed the tenths place in order to adjust the span. This is where I noticed a plus or minus .2 degree variation in the lower set point.

Rated 1 out of 5 by from Tx9000Ua I purchased this thermostat to replace an old Lux 9000 which had served me very well. To be honest I wish they still offered them. This unit is a mess. The temperature reading is not accurate. It reads off by at least 2 degrees from other thermometers I have. Also the unit does not come on at the set degree. It comes on at least two degree sooner than programmed. It has a program that limits how many times it can come on per hour which causes problems with cycling. Also all the information to program this unit does not come with it. You have to go online and download part of the instructions and even then some of it is poorly written. I would suggest that others stay away from this model.

Make sure you pick the right one! I just wired the same as my old thermostat, after determining what type HVAC system I have. I took a pic of the original wiring as well as wrote down what color wire was on what terminal. Some terminals on my original were labeled L1 and L2, on the LUX they are labeled just L and L2... L by itself is the same as L1. Go through the setup even if it appears to work right out of the box. There are a couple things in the setup that need to be changed. My second stage heat didn't appear to work correctly until I made a change in setup (I think it was the delay time).

Rated 5 out of 5 by from Absolutely perfect replacement thermostat Since Lux released a new revision of the TX9100U in 2014 I did not put much weight in the older reviews. I purchased the new TX9100U to replace our out-of-date thermostat that came with our new home. My main objective was to get something inexpensive that offered programming capability. The new TX9100U worked out very nicely. It was very easy to install in less than 15 minutes. I programmed the thermostat to kick down our heat to 62 at 11PM when we all go to bed and ramp the heat back on at 6:30AM when we get up; the programming works great and is sure to reduce our utility bills! and if I happen to be up late working I can easily temporarily override the program. I also like the large easy to read lighted display so I can read the thermostat display without reading glasses. The TX9100U maintains temperature at our desired set points and keeps our home comfortable. The new TX9100U did the trick for us at a decent price!

Rated 1 out of 5 by from not recommended I read the previous review about this model in this website, but I didn't believe it, so I went ahead with my purchase anyway. I ordered this unit online from Home Depot. I should have avoided it. I installed it last night, and it was fairly easy to install - certainly within 15 minutes as indicated it would take on the packaging for the unit. I bought the lux tx9100u to replace an older RiteTemp touchscreen thermostat that stopped working. Programming the daily times/temperatures was not very difficult on the tx9100u, but not as easy as my old touchscreen model. The copy button on this model is very useful to copy the program set for 1 day to the next. What I am very disappointed in is that Lux purposely programmed this model to not turn off the air conditioner at the set point temperature. I had my AC temperature set to 72 degrees today. My wife and I thought it felt like it was getting too cool this afternoon. So I went to the thermostat saw that it displayed a temperature of 72 degrees, but the AC was still running. So, I bumped up the setpoint temperature to 73 degrees. Several minutes later, the AC still had not turned off even though the room temperature on the display now said 71 degrees. I then moved the temperature setpoint to 74 degrees and then the AC turned off. I then looked at the manual to see if maybe the temperature swing was set incorrectly at the factory. The manual says to have the mode set to off and the programming slide set on run and holding down the hold button for at least 5 seconds to bring up the temperature swing adjustment. I followed the instructions, and after letting go of the hold button, the word "off" blinks on the display and you are never taken to the swing settings. I tried the instructions a few more times and held down the hold button longer for a few times for 10 seconds, but still no swing settings were displayed, and after releasing the hold button, "OFF" flashes a few times. I haven't tried the operation of the furnace with the thermostat today, since it was warm outside. As I was just about to click on submit this review this evening, I heard my AC turn back on. My current setpoint is 75 degrees, but the actual room temperature displayed is 73 degrees. I'm afraid that I am going to have to return this unit as this unit did not perform as well as my 9 year old thermostat that it replaced, and actually made the house uncomfortable due to not turning off the AC at the desired temperature set point, and there is no ability to access the temperature swing on my unit. It's too bad I have to give such a low rating, since the thermostat looks nice, and the bottons are convenient, but if a thermostat cannot keep you comfortable, what good is it?

Had an older version of this thermostat from about 15 years prior that had stopped working. This was a slightly different size but still works pretty much the same, screen is bigger, which is a help. Our system is very simple-- a 'gravity flow' heater, which is basically a box under the wall between the living room and the hallway that heats the air, which flow up through a grate in the floor. No fan, no A/C. Only two wires. Thermostat works fine for this. It comes with stickers so you can tag the wires in your existing system, and screws for mounting, you supply your own AA batteries. Only downside is a slight noise it makes when the screen lights up, which goes away after 10 seconds when the screen automatically goes off. Four settings per day, 7 per week. Once you set it up you're done. Controls are convenient.
