What happens if someone takes the batteries out of the thermostat? When you reset it, will it just keep the heat on at 71?

It will only go as high as you program it for. Battery will not change the program.

I purchased one back in the summer for the grand-daughter, so this is our first winter, but it is sitting out in our detached garage in cold Tennessee weather. It's hasn't been extreme cold yet, but you have given me an idea that I might put a folded up blanket over the back end where the battery is, just in case. Taking the battery out and bringing it into the house is not something I personally want to do. It might be an easy thing, but this 71 yr. old granny doesn't want that job.

I think we have the light grey one so I can't answer that question. When the power goes out there are batteries that allow the thermostat to continue to work. However, your furnace/AC will not be working. When the power comes back on the thermostat will re-establish contact with your WiFi and everything will be fine. If you go to the Total Comfort website you can set up an email message to be sent you if the thermostat looses contact with the WiFi. That is almost always because of a power failure. I love that feature as we live in Alaska and spend several months outside of Alaska at a second home in the winter. So I know when the power goes off and it notifies me when the thermostat re-establishes contact with the WiFi when the power comes back on. So if there is a lengthy delay I can call and have someone go and check our home out. Hope this helps.

No. This thermostat does not use batteries. This is a primary reason for my purchase.

Since we have owned it the temps have varied from 100 to -19... Worked perectly still on my first set of batteries also.

Nothing, what should happen? The reason you shouldn't use it above 32 degrees is you could overheat the the element or the battery. I don't use it as a battery warmer. It operates at temperatures well over 32 degrees but you have to have enough of a heat sink to dissipate the heat or turn it off and on.

I never leave it on all night cause i do not want to waste the batteries.But i don't think it would over heat.I would not put it on medal shelf it could short out and not work anymore.

If the temp. rises too much the battery may overheat and boil away the electrolite. I would think that it should be turned off if the temp. stays above freezing for several hours I turn mine on at night and off in the morning if the temp. during .the day will be warner than 32 degrees.

The thermostat retains the last settings if that is your question. If power is out, your HVAC is out of commission anyway :-)

Yes the thermostat's batteries retain the its settings during power outages. These batteries run down in about 1 day unless external power is applied however. The power from the thermostat wiring must be supplemented from an external source. I ran an additional cable from the furnace for this purpose and the thermostat now operates an monitors temperature in my vacation house. I also have a "NEST" thermostat ($250 @ LOWES) as well which has more features and is able to run solely on the 2 existing thermostat wires in the wall.

I leave mine on 24/7 and haven't had any problems. Thermostat works way better than the cheap Home Depot brands. You certainly get what you pay for.

Unit comes off easily- changing and setting temps is easy- the light on it is fabulous we did not change batteries I believe it works off of the wires u attach. As I stated before their booklet on this item is online at luxproducts.comm look in my previous answer. Also their number for tech support is 18562348803. Good luck this is an awesome item.

No battery backup in mine. However if the power goes out, your furnace won't run it's fan anyway. When the power comes back on, the thermostat will resume as left off. We have ours in a vacation home and the power goes off intermittently throughout the winter. The thermostat is always reset and functioning when I check back in. I really enjoy this thermostat for checking in on the house and the external temperatures remotely, and for turning on the heat before we arrive in the winter.

I have not left it on if I am gone, however the heat element does turn on and off automatically according to whatthe thermostat is set for. I think you would probably be ok.

Hi Claude, This thermostat opperates on DC current. It is powered by a transformer on your furnace that converts your 120V AC corrent to 3 volts DC current. (You already have that transformer in your furnace. It operated your previous thermostat.) It also has a 2 AA Battery back-up in case the power goes out. Your local power companies Load Control Device will have absolutely no effect on this unit. Gil PS - it is a great thermostat. Easy to program and works like a dream.

No, this is strictly a 110V setup. The heat is on or off. Thermostats are usually low voltage.

No, it doesn't. It resets if you unplug it. Regardless of whether it stays plugged in or not, every time you turn it back on you have to manually set the "thermostat" function and temperature, although if it hasn't been unplugged it will default to the last temperature you set it on. There is a light on the front panel so that you know whether it's on automatic/thermostat or just "on".
