If there is a power outage and the power comes back, is it necessary to reprogram the timer or will the old setting still work?

They come with a battery installed displaying a time so I believe it will hold your settings

Our power went out for an hour last week. The timer did not have to be reset after the power came back on. Also, I found it easier to program the timer if I plug it into an extension cord to program it, and you can disconnect it to plug it in directly to the power receptacle on the wall without losing the programming (if it is fully charged).

There seems to be a battery inside because I have unplugged this several times and it keeps the settings. BTW, I really like this unit. Only issue is the instruction guide, but once you figure out how to do the setting this unit is great.

if it's set at on when the power goes out, it will automatically come back on when the power is restored

Unfortunately the default setting is "off" for these devices. Meaning once the wall unit is plugged in or every time the power goes out and comes back on, you will manually have to turn the device back on with the remote or button on the unit. And there's no way to change this setting unless you take apart the unit and reprogram it. It's a huge flaw with the unit. Otherwise it would be perfect.

No, this is a strictly mechanical switch, you need to manually reset timer after power failure. I have been using this combination of timer and electric water heater for close to 30 years and believe it is even superior to the current fad of "on-demand" heaters.

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.

I don't understand the answers, mine was never a problem with time after a power outage, but I did hate the fact you could not program all zones, so I sold mine, and bought the new model that does. The unique thing about this timer is how simple it is to run and to program.

I have had the power go out a few times and everything went back to normal and the wifi still worked. Once my router went to its default setting and I lost my network name when it booted up and had to reprogram the router and the reset the thermostat through Honeywell. I automatically got an email telling me that the wifi was not connected. As long as your router starts up as before the outage I think you should be ok.

It depends is the outlet on a timer or are you going to manually cut the power to the lock.

Hi Steve. No, there is no programming available on this unit. I was going to suggest an appliance timer but I think that after the power to the unit was disconnected it would not come on by default when the timer restored power. Hope this helps

I can confirm that no, it would not come back on after a loss of power. You would need to manually hit the "power" button to make it turn back on.

Yes, so long as the power stays on it retains its clock and timer settings. The batteries are only to preserve settings in case of a power outage.

Yes, This is a simple 24 hour clock timer. I wouldn't bother for short power interruptions but for long outages you should check time every once and awhile. You also need to adjust for daylight savings time twice a year.

As long as the normal power source to the timer is still available no reprogramming will be required as it will not lose power.

Yes, the clock and all other settings (i.e., zone watering times) are retained during a power failure. No battery is needed, everything is stored in non-volatile memory:Quoting from the RainBird SST user manual:◾No need to reprogram after a power outage. All timer settings are stored indefinitely in memory. No backup battery needed!

No. This is the only problem with this product. It loses the program when the power is out. So you need to redo it. It is easy, but you have to program it again. M

Not sure what you mean by "reset". The on/off functions are set by mechanical stops and can only be set/reset manually. If the power goes off, the master timer stops running as will any electrical clock. When the power comes back on it will pick up where it left off. In order for it to come on and off at accurate times, you will have to reset the dial (not the stops) to reflect the correct time.

No, the timer is strictly a Shut Down Timer. Also of concern to some is a Power Outage will cause the haeater to stop working and it will need to be manually restarted. I expect both of these features were designed this way because of safety concerns, for instance a heater starting in a dangerous environment while unattended.
