I'm willing to be proven wrong on this, but that is my experience with the "lux" thermostat. Also, there is some confusion in the way Amazon is listing this; the LV2 is a double-pole thermostat, while the LV1 is a single-pole thermostat. Theoretically (if the damned thing worked at all) it is possible to wire up the LVV2 as a single-pole thermostat, only using one of the two microswitches inside.
But it still won't be sensitive enough to know what that median temperature for turning on and off is; you'll overheat and get cold before it kicks in.
By the way, I tried every possible location including holding it in front of the heater vent (where it did have the decency to turn the heat off, I have to admit).
Unless there is some fact or factor I'm not understanding, putting this product on the market was an amazingly crass and cynical act.

Ok, I would have to agree with the other reviews that have had problems with this item, if only i had read the reviews before purchasing two of these items then i wouldnt be trying to return them right now, afetr installing these thermostats i noticed that with the room tempreature being 73 degrees these thermostats would not turn off untill i turned them down to around 55 degrees, that gives it around a 17 degree difference. so if you want an acurate thermostat do not buy this item, put out some extra cash and purchse the LUX ELV4 programmable line heating thermostat, i now have two of these units and they are the best, they have a digital thermometer built into them so there is no need to worry about checking your heating system after programming these devices, your room will be nice and warm when you wake up and will turn off when you want it too.Best Deals on Lux Products LV2 Line Voltage Double Pole Heat Thermostat, Sterling
I replaced two old thermostats with Lux LV2's in my future retirement house. I had checked them with an ohmmeter before installation and they seemed OK. So I merely made sure they would turn the baseboards on, set them back to 60 degrees, and went home (85 miles away). Fortunately my wife and I decided to go back the next day instead of the following week. When we got there, one of the rooms was over 70 degrees and the baseboards were on. I had to move the dial back to below 50 to turn them off. The other room was cold. I needed to turn that thermostat to 80 before it came on, but then it didn't turn off until below 50.I pulled both of the Lux LV-2's. Replaced one with a Honeywell digital and the other with a Honeywell mechanical. Both Honeywells work well and the $20 mechanical holds within about 3 degrees total.
Finally, I took one of the LV-2s into the electronics lab at work. We put a 500 watt load on it in an enclosure and it would not shut off. The thermostat frame was nearly too hot to handle but it would not shut off. After it had cooled we again tested with the ohmmeter and it again seemed OK when cold and not under load.
Buy another brandthese are poison.
Honest reviews on Lux Products LV2 Line Voltage Double Pole Heat Thermostat, Sterling
The thermostat keeps a narrow temperature range which is good. The only problem is that the temperature setting dial is about 6-8 degrees off. I set it at 60 to get a 67 degree room.Find helpful customer reviews and review ratings for Lux Products LV2 Line Voltage Double Pole Heat Thermostat, Sterling
I tried to save some money by changing out our old thermostats. Going cheap on the thermostats was a mistake. This thermostat uses the old method of bimetallic material to switch on and off. It was poorly calibrated and when the room was 70 it needed to be turned past 85 to work. They would get stuck on and create all sorts of problems with the room temperature. I returned these chinese made hazards and purchased ones that use a chemical cell to detect temperature. The electronic ones are + or 1 degree. These units are + or 20 degrees and get stuck on. Forget them. We returned them. Round two on the install!
