Question: How loud is the click when the thermostat activates? I'm trying to find one for my bedroom.
Document: When the repair man attempted to work with the unit, the screen went haywire and could be made to do nothing. He replaced the unit with another one that he had available. The unit was installed for about 60 days. Now I'm trying to figure out how to return the unit and possibly get a refund, but I no longer have the packaging. I have never used Lux before and one unit is working fine. Just be wary of the product.
I've been wanting a programmable thermostat for years. My husband said finding the right one at a cost that we could afford would be difficult. I found the lux ones and read through their recommendation chart to find the one we needed. The Lux9100E had all the right features. I knew my husband wouldn't have time to install it so when I read how one of the other posters emailed Lux's Customer Service Dept.
I bought this product after learning that standard programmable Honeywells do not work for 3 wire zone valves. This one said it did and looking up the manual online I saw specific wiring directions for such. This was the cheapest model  I could find that said it would work with 3 wire hydronic zone valves (baseboard heating with an old school Burnham Boiler). The thermostat was easy to install and worked properly both opening and closing a white rodgers 3 wire zone valve.
* The one good feature about the TX9100E is the price; not bad considering the higher priced Honeywell's.The one serious drawback of the older TX9000 was that the Up and Down buttons had little height above the face of the thermostat; and after a few years of use, the buttons failed altogether.So, overall, I'm disappointed and will be on the lookout for a replacement.
I had a hard time picking a thermostat because they all had some bad reviews, and I'm glad I didn't pick a cheaper one than this because it's been very good. We did have kind of a hard time installing it, but with a little help from google we were able to do it. Other than that, it seems to be measuring the temperature correctly and keeping the house cool. Good purchase.
Since I am using the optional battery backup mode, I found that I could sit in my recliner and program the thermostat, then click it into place on the wall mount. I don't use a lot of alternate programs ... just the same one each day. The "copy" option worked great. Just set up your first day, and copy it to the other days. Simple.I have a heat pump with a second stage (very expensive to run) electric heat strip.
I've been using the thermostat for about 8 months now, and I'm still very happy with it... especially for the price.The only thing that bugs me a little is when the fan is set to &#34;on&#34; instead of &#34;auto&#34;, and your heat or air cycles on, the fan will shut off completely and start again with the heat/air. It's really insignificant, but one of those things...
I hooked up this thermostat as directed. Instructions are clear and I have a very simple system with little chance of mixing up the wiring. The thermostat went through one on/off cycle for air conditioning, then quit. It still works with controlling heat. I'm working on figuring out the problem with vendor. At this point, I can't recommend the product.
Both looked at the Lux thermostat and complained about it. They say Honeywell is the only way to go. But they both kind felt the first HVAC guy blew out the circuit board.Anyway, I now have a new heat pump for $5000, (the third HVAC guy did it, not the first, I'm not THAT stupid!) and a new Honeywell thermostat since all of them refused to use this one.
Installing this thermostat wasn't as easy as I hoped, but that was due to the age of my heatpump. One call to the Lux helpdesk answered my questions and I was up and running! The thermostat itself looks great, is easy to program and works wonderfully. The convenience of 4 intervals during the day should make for some savings as I can set the temp for when I'm sleeping (I like it cold), not home or whatever.
Answer: yes
