Is there a backup incase of power failure to remember the program temp setting?. Will I have to re program the unit when power is restored?

I have unplugged my freezer which the Ranco controls the temperature. I do not reset the unit it stays on settings until they are manually changed.

Yes, the unit will remember the settings without power. Mine has been unplugged for 3 months and it remembered the settings I last used for the set point temp and the differential range all in the proper units.

I have had many power failures but I never had to re-program this unit. I am not sure how it does but does remember settings. Please note the Power failures we have seen here only lasted a few hours maximum. I have to reset all radio-clocks that is how I notice power failures...

No, the settings are stored in non-volatile memory, so power outages or unplugging doesnt affect settings. I set one controller aside literally for years. When plugged back in the last settings were there.

I own one of these, and can't answer this question with technical accuracy. I can however answer it with experience. In sub zero temps outside, the inducer motor on my furnace failed the other day. I had to kill power to the furnace for 4 or 5 hours while I found a replacement part and installed it. The unit is completely powered by the furnace so it was without power the entire time. The thermostat was not an issue. It had been without power for at least 4 hours and once power was restored it still retained the router settings and I did not have to reprogram it. I believe all the settings are stored on the Website and all the thermostat needs to retain is the Router setup. It appears to store the router info in the BIOS. Hope this helps. I have only used this for a couple months, but so far it is perfect.

I don't think so. It will reset itself during a power failure (or being unplugged) back to the state it was in when it lost power.

If you're having so many regular power failures you should have backup power anyway since that kind of thing is really, really bad for your system. At some point you're absolutely going to lose data or your system will become unstable. - Trust me, I work in IT.

I've had mine running now for over 6 months , never had to reset it or anything , very reliable so I would say commercial use would actually be even better for setting up a scheduled heat and ac unit. I would say yes.

Hi Carol: I would say that you would have to turn the heater back on but I'm not sure because I have not been in a power outage since I have owned it. Sorry I couldn't be of more help.

Yes it does "remember" most settings. After a power failure, all settings remain except the date and time.

I do not recall if we've tried that.. but would guess it does since it needs to keep a lot of config stuff saved - particularly if you get the WIFI dongle thingie..Actually, now that I think about it, I think we've had some power failures since we installed ours and I don't recall having to do anything after the power came back.. Perhaps someone else can chime in too to ensure I'm not wrong..

That has never happened to me, so I can't answer specifically. However, if I unplug it, it must be reset again, so I assume the same would be true of a power failure.

Yes, it does retain it's setting. I don't know if there is a time limit for how long the setting will be kept, but I've seen it retain the temp setting after a several hour power outage. I have two of these installed and they both returned to their set temps following 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.

I think the default setting is reverted to, as indicated in the owners manual. Haven't been around during a failure and re-power to tell for sure.

Never plug a power backup unit such as this into a protector strip. It can cause power surges and other issues.

Can't say that it will happen 100% of the time, but I just experienced this last weekend, was away for a couple days, got an email saying the thermostat wasn't able to connect to the cloud site in over 24 hours, Called my neighbor, he confirmed the power was out, but by the time I got back home everything had returned to normal, the power came back on and the thermostat reconnected without issues. But when dealing with wifi and the amount of variables you could be dealing with with any access point, I'd guess your mileage may vary.

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.

I have not come across that problem yet. we have had no reason to shut it down, and have had no loss of power due to outages. when this was installed for me in a large walk-in cooler, wine cooler, it took one month with the manufacturer to be up and running. Your best bet is to just email to the manufacturer. I worked with them on and off for a month making adjustments and they were absolutely phenomenal to work with.I think the coolbot was an excellent investment. you just need the right system to pair it with. again manufacture of was key with that.

It's a no-touch system. Plug it in, it will go through a self test attach the equipment you wish to supply and forget it, it will take care of itself. I've had mine for a year or so and it has never failed to do it's job when the power failed. I use it to power both my cable modem and router, and no problems occurred during power failure.
