Product Review: Lux TX500E Thermostat
I was thinking of doing this review a week or so ago on Amazon.com. They have over 40 product reviews for this thermostat. The majority seem to give it 4 or 5 stars. I won't be nearly so generous.
I held off installing the unit for over two months since it recommended turning off power to the room while doing so. I didn't want to hassle with that. Finally I gave it a try without turning off the power. That worked ok, except the tiny screws were a pain to deal with, as this amazon reviewer explained. I must have dropped those screws 30 or 40 times myself, and lost some of them.
Once installed, I put 2 AA batteries into the back of the face piece and popped the face piece on to the wall mount. Then we had to figure out how to program it.
The instructions, as with most things nowadays, were in print so small I couldn't read them with my naked eye. I even had difficulty with reading glasses. Connie could read them easier so she took charge of that.
One mistake we made was trying to program it while it was mounted on the wall. It was too high and was over a table making it hard for her to read and adjust it. We should have just popped the face piece off, programmed it, then popped it back on. Didn't think of that until much later.
Once we thought we had it programmed, we had to test it to see if it would go on as I still wasn't sure I had the two wires attached properly. Both wires were black, instead of colored as the instructions suggested they would be. After some tinkering with the temperature settings, the heater came on so I knew I had it right.
Then we started hassling with the main problem we have with the unit: The temperature gauge- or thermometer- doesn't read the temperature right. I don't know it's ever gone below 58 degrees since we installed it, and we'd still feel quite chilly in the house at times.
We have a thermometer/ barometer on the wall just below the unit and it always shows the room temperature four degrees lower. A soil thermometer we placed next to it shows the temperature as 10 degrees cooler. We don't know which one to believe, but I know it's not 58 degrees in this room when it's 40 outside, we haven't had the heater on since the morning before and I'm still cold.
As I sit here, the heater should be on, maybe. I believe Connie set it to 60 yesterday morning. It should start the heater when the room goes below 60, but it shows the temperature at 57 right now and no heater. I'm guessing that's because we might have it set lower for the morning hours or the weekend? I'll have to check that. I forget what times I had it set for.
The reason I bought this unit was it allowed you to set night and daytime temperatures, with special settings for weekends. It's kind of hard to figure those times out when we're still trying to figure out what the comfortable temperature ranges are with the unit.
One other thing I noticed while reading some of the Amazon reviews, is these units don't seem to last very long. Some say just a couple years. Some say up to eight. How soon will we have to go through this hassle again? And I hope it doesn't stop working in the winter!
I'm wishing now that I didn't bother buying this thing and just stuck with the old style manual thermostat we used without hassle since we bought the house. Unfortunately, I threw that away as soon as we had this unit up on the wall. Maybe I'll give this unit 3 stars, if we can ever figure out the right temperatures and get it programmed right.
I'll probably give it 1 star if it stops working within the next 2 years.
