  • SAFETY HAZARD! Wired correctly to house, but SHORTED OUT internally
We replaced all thermostats in our house with the ELV4 (five total). They worked 'mostly' fine for the last five or so years. One would occasionally fail to turn off, resulting in the bathroom getting overly hot. Oh well, we thought, 'Might be something to do with bneing installed on an exterior wall. We can live with that.' Well... tonight one of them burned up when I turned the thermostat to 'off' since the windows were open! It went POOF right before my eyes! It was wired perfectly correct, and this one worked perfectly fine for five or so years (home office) prior to burning up. The electrical box shows no signs of damage - the burn marks are entirely within the thermostat. The switch shorted out and is now melted permanently in the off position. It also tripped the circuit breaker in or panel, but somehow damaged the breaker - it can be reset to on (did this AFTER safely disconnecting this faulty P.O.S. thermostat), but cannot be manually tripped fully off. Edit: We've had these ELV4 thermostats 7 years and one week (found them in my Amazon purchase history). ... show more

  • Hopeful, but not happy
Was really surprised for the lack of programmable single pole thermostats out there. I don't want or need my heater running all day long while I'm at work. This one was most affordable I found that did the functions I was looking for. My biggest complaint is how stinking loud this thing is when it kicks on and off. Which, as you can imagine, is a lot in the middle of winter. I can't believe there weren't more complaints on here about that. Also, the new box is very deep so install was a bit trickier than you'd think. Lastly, this thermostat does not fully cover the existing single gang cutout. My other one was just fine, but you can see the jagged sheetrock on either side of this one. If it wasn't so loud, I was going to fashion something to cover the eye sore. Lastly, I don't believe it is accurate. I like the room cool at night and initially set it for 66 degrees. 66 made me kick the comforter off...in the middle of winter. I dropped it a degree over the next couple nights and ended up landing on 63 as my comfortable setting. That obviously is not what it actually is. I also could have lived with this and made the necessary adjustments if the noise wasn't present. ... show more

  • Perfect Thermostat for Cadet Wall Units with Enclosed Fan.
If you have a Cadet wall unit with integrated fan, this thermostat is for you! My previous Honeywell unit even when configured in "fan mode" had the heater cycling on and off every couple of minutes (the Honeywell unit works great with electric baseboard heat). The LUX ELV4 solved the problem. It is the only electric heat thermostat that I have found that has a "swing setting". This enables you to set a spread of temperature before the heater/fan will cycle. On setting 1, the temp can only vary about 1/4 of a degree before the thermostat energizes the heater. On setting ten the swing is approximately 2 1/2 degrees before the heater/fan goes on and off. For my needs I've found that setting 3 allows a variation of 3/4 to one degree before starting the heating process. With that setting the heater energizes for about 8-10 minutes every half hour or so. Perfect for my needs. You may have to experiment with the setting bit to get it right for your climate and building construction and heat retention. One other note, when the thermostat turns the heater on OR off, it will stay that way for 5 minutes before the thermostat allows it to cycle again. This is to prevent unnecessary switching of your heating system. Should help preserve the life of the fan in this application. It makes no difference in electric baseboard heat. There is an audible click but it does not bother me. Also, the model I got does not have the ON/OFF switch that is accessible without removing the cover. It must be a left over older version. This is a minor inconvenience . Love this thing. ... show more

  • Got an oil fired boiler and want a digital thermostat? Look no further...
Finally, a digital thermostat for my oil fired boiler! If you have an oil fired hot water boiler and radiant floor heat then this product is for you. What you'll likely find out is that these systems use 'line voltage' and not 'low voltage' as many oil furnace systems use. I'm pretty handy around the house, and I thought I was pretty well educated on home thermostats. Oil furnaces and boilers all use low voltage to run a thermostat, right? Well, nooooooo, they don't. I was surprised to learn that after buying a plain old digital thermostat to replace my analog dial mercury switch. Pretty much every thermostat at a big box retailer is going to be low voltage because that's the most common. When I stuck one of those on my wall it did pretty much nothing (and may have gotten damaged in the process, though thankfully there were no whips of smoke billowing out). So, I pulled out my voltage meter and did a quick check and found out, "holy crap this is 120v AC." Hence began my internet search for a 120v thermostat. Come to find out, the 120v, or 'line voltage' system isn't too common. I wasn't able to find many thermostats that would fit my application, and many were specifically for electric baseboard heating. A bit more research brought me to the Lux ELV4. Finally, I had found what I was looking for. This is a very solid piece of hardware, and priced pretty competitively with low voltage models (though being more common they are generally cheaper). The ELV4 provides separate programming for weekday and weekend use. You can set two morning temps and two evening temps which generally cover 'wake up', 'go to work', 'return from work', and 'go to bed'. The clock display can also be set to show 12 or 24 hours. I have no doubt that the precise control of this unit will far exceed the performance of the old mercury switch (which most building codes don't allow for these days anyway). I'm going to watch my oil bill, but I'm betting I'll be spending less now that we can more finely control the temperature in the home and avoid the 'thermostat tennis' habit. So with all the great features, I wish there was one thing that could have been included - a back-light. You're going to have to turn on your room or hallway light if you want to see the display in the dark. A darn shame since that's really the only nit I have with the unit. I would give my review 4.5 stars if possible, but since I have to choose 4 or 5 I'll still go 5 because the rest of the unit is so solid. Finally, a word of advise, READ THE DIRECTIONS when you install. Yes, the wiring is pretty obvious (line voltage 'in' is red and 'load' out is black), but there are a couple things that can bite you if you don't RTDT. Obviously, there is a front panel that flips down to allow you to get to the programming options. What is NOT so obvious is that the face of the unit separates from the back mounting plate and there are MORE options BEHIND the face of the unit. Specifically, there is an on/off switch for the heat which can be used during the summer when you don't want the unit to turn on at all. The thermostat is shipped with the switch in the OFF position, so if you don't turn it ON you may think you have a DOA thermostat. Also, there are two 'dip' switches on the back to set the temp to either Fahrenheit or Celsius, as well as for the 12 or 24 hour clock. I'm attaching a picture of the thermostat with the optional trim plate (sold separately) for your viewing pleasure. Happy heating! ... show more
