Tomorrow is the day

neither of the units recommended by harman in bogies post above are pursinewave or at least not that I could find, so I'm not sure which is prefered or if my stove even goes into shutdown automatically if power is lost. Maybe lousy could tell us more

 

Wait, first they can't burn DF's and now they're picky with UPS'? What is the world coming to?

 

That UPS should put the stove into shutdown mode and have enough battery power to do so cycle the blower for 15-20 minutes to make sure fire is out and smoke is evacuated. I would test the one you bought (after charging for 24 hours), to make sure it will do what you want. It most likely will, but you want to know before it is needed, not when it is needed.

If you were looking to actually have a battery back up to run the stove for a long period of time (not do a controlled shut down), then you would need a pure sine wave.

 

Great info, thanks B. The UPS units we have do not put the stove into a shutdown sequence; the stoves keep running like we never lost power in the first place. In our particular situation, that is the desired behavior.

 

It's the length of operation dictating the usefulness of UPS. If you're home no problem but if you're away and having a puresinewave UPS it will eventually deplete itself and stop while the stove is still chugging along

 

Thanks B no just looking for a controlled shutdown.I will give it a test.

 

Harman no longer sells the Surefire512 and hasn't for a few years now. The Allure50 comes set from the factory to accept a UPC, and recommended in the Owners Manual for the Allure50 is APC model BE750G, or Tripplite INTERNET750U (ugh, don't like Tripplite!), I don't sell UPC's when someone can get them cheaply from Amazon or Staples, etc.....I believe that the APC is a Stepped Approximation to Sine Wave, rather than a pure sine wave.....I was told by Harman that this is basically how the unit detects an outage.....the difference between the pure sine wave of line power versus the stepped approximation.....but, I am no electrical guru, so, I am sure others here are MUCH more qualified to comment. Other models, hey, maybe, but they aren't in the Allure Owners' Manual. I don't like Tripplite, as I have had reliability issues with them on our POS system at the store.....they should last more than a few months (and this included the replacements!)...utter garbage as far as I am concerned.

I also believe the UPS thing will work with any Harman "E" or "F" revision board, not just the current TC models which the Allure is.....you can also turn the feature off via the dip switch settings, but I am not going into that here.

When the power goes out, the circuitry detects the difference from line power versus battery power from the UPC.....then, the only thing that's going to run is the combustion fan, and its going to pulse, basically burning the pellets already lit, so there isn't smoke seepage out the possibly leaky pipe, or gaskets in the stove.....this seepage in some cases can be pretty profound.

 

Hmm, never heard that it was the sine or non-sine power that allowed this, I thought it was backup model driven-but it actually makes sense. I do know that board revisions later than mine would go into shutdown when on battery power when on "approved" models. Maybe Lousyweather can confirm if it is the power type or the actual model of backup.

 

read above......I do believe its detecting the change in curve to determine whats going on......

 

Yeah I posted before reading to the end...

Never thought about it using the curve to go into pulse mode and it does make sense. I always figured it of wanted a pure sine genny, then the battery would be the same. Moot point for me as my 2009 board isnt REV e or later but I learned something new today

 

youre correct with the genny......it would want a pure sine wave......if not, its just gonna pulse, unless you turn that option off in the dreaded sitch settings...nut I don't wanna go and open THAT Pandoras box again!

 

damm Harman makes a smart stove going into a sort of shutdown when on battery power. I feel bad for all the others

 

yea, but don't worry, all the Hormone haters will be chiming in soon about how it doesn't matter, and their $20 stoves are "just as good".......hold on, gotta answer this call from Dos Equis after I get done with the call from Chuck Norris......brb.....

 

It would be nice if Harman updated their approved UPS units because the APC 750G is no longer available.

 

maybe, but you cant keep rewriting a manual whenever someone changed their lineup either.....

 

I don't think it would be very difficult to change a few words to ensure their customers are purchasing their recommended unit

 

So if a Harman that will shut down on a non sine battery backup, will it also just shut down on a non sine genny unless the feature is turned off?

 

Maybe change their recommendation to a non pure sine backup-if that is what makes it go into the shut down mode.
