Does this have a battery backup? We lose power often and reprogramming every time would be a chore.

Instructions state "Power outage: The screen is blank. Only the time must be set if the outage lasts more than 4 hours; all other settings and programs are permanently saved." Hope this helps answer your question.

Below is what the tech specs say about loss of power. There is no replaceable battery that I see. I suspect it the local time is saved via a capacitor type back up and the other settings are stored permananetly any time you set them. I have only reset mine once and that was because I wanted the light to come on later because of holiday deco's on the porch.Power outage: The screen is blank. Only the time must be set if the outage lasts more than 4 hours; all other settings and programs are permanently saved.

The unit maintains all settings during a power failure up to 4 hours. After 4 hours all you need to reset is the time of day. You will need a deep wall box to install this controller.

No,There is no battery back-up, but it is very easy to reset time . The unit has saved me a lot of $$$$$ .I have my hw heater set to come on 2 hours a day.

No. I use a hydroflash system to detect and control Insteon devices. We had a 20 hr power failure recently. I came right up when power is installed. Doesn't you controller have battery backup?

Batteries to keep program when controller is disconnected from 12volt power otherwise you need to program again

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

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.

No backup battery inside unit. But.it.is.powered through the backup battery on.the alarm system.control board. Bit even.if that fails, no need to.reprogram Everything. Just basic time and date.

It does have a battery back-up so if the power goes off, it keeps your programming.

Yes, there is built in backup. I don't know how long it will last, but definitely long enough for the typical power outage. Mine has been unplugged for over a day now and the display is still working (unlike the timer itself, which is permanently off, and ready for recyling).

Yes. It has two timer modes you can set, for example one for morning and one for evening. These are the two LEDs beneath the LCD clock display. However, there is no battery backup when the power fails but setting the timer is very easy. We use this feature in the morning to save time.

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.

No battery backup is included in this package. Check the website to see if you can purchase one separately.

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

No, and this is horribly annoying. Even a brief outage resets the clocks, alarms and everything - you have to completely reprogram everything. If you have power issues at all I would advise against it.

Yes. Word of warning...if the power goes out, you will need to reset the timer. Also, this product lasted about one year and died on me. Did not replace with another. Went to Lowes and bought one that is digital and has battery backup ($25) seems to work great, but time will tell

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