Is it able to use back-up batteries that enable the thermostat to retain my settings when there are 30-second power outages?

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.

Jim I have this thermostat with a battery installed and it does sustain through power failures.

Yes, the thermostat has batteries which retain the settings for power outages.

It's been quite awhile since I installed my timer and I don't remember now what number it was----but I know that it did take a back up battery. Are you sure your's does not? I've never seen one that didn't? But I suppose that it's possible that the newer models might use a system that won't dump your settings when the power goes off. I haven't researched your model number so I can't say one way or the other for certain.

No, but in the event of a power outage, it stores the programming for later. (No need to re-program.)

For prolonged power outages, it's possible that it would lose its settings. However, for brief power failure... it comes right back online when power is restored. Also, it DOES have a programable choice to set a Daylight Savings time option. It's a good thermostat... I'm happy that it was this that failed, and NOT a break in the heating elements under the tile!

If the thermostat is wired directly to unit and pulls power from the unit it will stay lit all night. If it runs just off the battery it will not.

The best response I can gives that it depends on the battery (i.e. lithium, alkaline, standard etc.) and the length of time that the battery has been in use prior to an outage. Additionally you can prolong battery life by turning off the units using the remote during the day for long power outages. Keep in mind that the units use leds so battery use is longer than any incandescent light bulb. Another good feature is that each unit has a low battery indicator which means batteries should be replaced even if you have not had a power outage (this is comparable to smoke and CO detectors which will beep when the battery should be replaced). Best advice I can give you is to have extra batteries on hand to handle long power outages of several days. All you will have to do is replaced the batteries in any unit that fails.

In my thermostat there are no batteries. It's hardwired in. When it started to malfunction I had to replace the whole unit.

I have had several brief power outings at my house and I have not had to reload the settings. You can save a config file to your computer in case you need to restore it to make it easy.

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

If you don't mind that the back light will not be constantly on, you can run this thermostat off of batteries. If you have the wire providing power to the thermostat, you can set the back light to stay on which is very nice at night. The batteries at this point provide backup, but then if there is no power, the fan in the house for the HVAC system wouldn't be working either. It's just there in that case to hold settings including the time and date.

If you unplug, timer has a rechargable back up battery inside incase power out or disconnected by accident, to save the same setting.

Not that I know of. Anything plugged in has a battery back up. I am in an area of frequent power failures. More than one a month and it has not been a problem with the security system. You could call GE, I think it is GE/Jasco for the security system. Sorry I don't have the number with me. They are very helpful.

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

No, at least not that I can find. I actually tried that myself since I own a 2 story home. It is much hotter upstairs in the bedrooms then downstairs where the thermostat is, so I was hoping to take it up there at night. You can take it off the wall and program it if you have batteries, but that is about all.

It does *not* have a battery backup. Some settings survive a power outage, but some do not. For example, the setting to *not* go into power saving mode is not preserved; the "standby" mode - you have to reset the "standby" power level whenever the power comes back on - to disable that feature is you set the "standby" power level to 0 (zero) watts. The option to turn off the PIR motion detection feature does keep its setting when the power is restored. I don't know what happens to other settings that I do not change from their default values.

Your power source is integrated into your thermostat wire. Its not a separate power source. Most HVAC systems have a 24v power integrated. The battery is just a back up and to keep your settings.

My best guess? No! I was surprised when I replaced my non-WIFI version of this thermostat with the WIFI version. The three double or triple A alkaline batteries in the non-WIFI were replaced by a single, flat, sort of mercury-looking cell in the WIFI. So this single cell is not going to power anything very long - maybe just preserve settings in a power failure. A final comment is that Honeywell has a surprisingly good email technical assistance system. I would suggest asking the experts.
