Does this thermostat use a battery for backup?

No they don't have battery back up. They are great though and I now have them in every room of the house running baseboard heaters. With the exception of the one running the gas fireplace. Battery back up is usually found in the programmable thermostats so it will save your settings in the event of a power outage.

No battery backup as the other responses indicated already. It's worth mentioning that there is some sort of memory function so that it "remembers" the temperature setting when the power does come back on.

Does not require battery backup. Works only on power that is delivered to the heater.If power goes down to your heating, then battery backup would not do any good anyway.Works very well in this manner.

No. It is just an electronic thermostat. And BTW it has been installed and is working very well. I may order some more to replace the old mechanical thermostats that are getting some age on them. I do have a thermostat which I use to control another rom that is programmable which will stay programmed during short power outages but it does not have a replaceable battery Hope this helps.

I'm not sure, because we use it as a battery backup to our server. The times I've needed it, we've gotten at least 2-3 hours of backup for our server before our electricity came back on.

Not battery operated. Does have battery backup, in case electricity goes out.

Under battery replacement, it mentions that if it is wired for AC, the batteries will be used for backup, but I do not find any info in the manual showing how to wire it for AC. therefore I'd call customer service at 1-800-468-1502 or their website at http://yourhome.honeywell.com.

No. It has no batteries to use for a backup. So if the power quits, so does the phone

Powered by the furnace wire but has a battery back up in case the power goes out, then you don't have to reprogram it.

Yes, the unit plugs in and the battery acts as the back up. Worked great for me this spring.

I believe if the batteries are dead or missing, the thermostat won't work and the heater will not come on. It makes sense but I never tested it.

No, you have to connect it to your battery or a/c. You can use the 12 volts that runs the system.

Gee I bought it awhile ago now and it plugs into an outlet, but I checked the description on Amazon and it doesn't say there's a backup battery. There is a little red light though, so if it were to turn off, you'd know it is not working.

Yes, this one does, it uses the batteries to run the clock, and programing. It is a great thermostat, mine is fantastic........Mark

This is a wired thermostat. While the unit does have internal batteries, I believe that they are designed for backup since the primary power should come from your system.

No battery backup built in but it uses the battery from the the alarm system. It has retained my zwave configurations after being disconnected. Most of the alarm programming is retained on your alarm system. IP address and such is usually DHCP.
