Question: Does it run on batteries or is powered by the "C" wire from the furnace?
Document: I was initially drawn to the backlit Lux TX1500E model because it could be powered by either 24 VAC or AA batteries, but the reviews indicated some A/C control failures caused by bad contacts when removable, processor section is docked back onto its wall mount.So I chose the simpler TX500E model instead, based on the better reviews. It's nearly identical in function and dimensions to my old Honeywell unit. I actually mounted the TX500E using the existing screw holes/anchors.
I bought my first Lux 500 thermostat on a Sunday morning in January 1999 when it was 30 degrees outside and the existing Honeywell digital/programmable thermostat (roughly six years old) had failed. I was waiting at Home Depot when they opened their doors at 7 am, and choose the Lux 500 from their available inventory. The house has no A/C, only a forced air gas furnace.
I was researching programmable thermostats and was shocked to find this on Amazon. This looks like the exact thermostat that I installed many years ago to replace the original crappy mechanical thermostat in my new house. To my surprise, this Lux thermostat has worked flawlessly for more than 10 years. I used to work as an HVAC technician so I know a good thermostat when I see it. The thermostat has some very good features like a run time delay to protect the A/C compressor.
used it on a Coleman Presidential 2-wire system and it works great. I recommend this as a replacement as I was told it couldn't be done
I found it easy to install and easy to set up. Nice product. If you want to adjust temperatures for different times of the day for A/C or heat, this will do it.
Like the Lux TX500E-10 Programmable Thermostat but had difficulty setting it up. My old Honeywell thermostat had 5 wire connections and the Lux included instructions couldn't handle it. Unlike the included instructions, the Lux website instructed the user to call the technical staff if you had a 5 wire setup. I was able to resolve the issue with their technical staff by phone.
I called them during the installation as the wiring color for one wire in my previous Honeywell unit was different and caused some confusion. Other than that, the installation was done in less than 5 minutes. I am a handy man myself so the time may not be representative of someone not used to working with such things.One feature which is sorely missing in it is the capability to program for vacations! I had to leave the house vacant for over two weeks and couldn't program it for that.
The TX500E Smart Temp Programmable Therostat that I purchased was easy to install. I had never installed a A/C themostat before this. But I can tell you anyone can do it. It took me about 45 minutes. And that includes reading the instructions a couple of times.Once it was installed it has worked perfectly. I have only had it about 3 weeks so far and no problems !
It took a few minutes for me to replace the old thermostat with this one. Then it took a few minutes more to figure out how to program it. Time of day settings I guess weren't something I was expecting but they have kept the furnace from running quite as often.
This does what it needs to do (turns the furnace on and off to regulate temperature), but the temperature sensor is inaccurate. It reads about 2 degrees high on my unit (which I verified with a calibrated laboratory thermometer). I was wondering why it felt cold in the house when I had it set to 68. It was actually 66!
Answer: yes
