My Sabrina just went nuts

[Drew65]

Just woke up to 75f in my bedroom. It should have been 68 so I wandered out to check and the stove was roaring away and it was 100f in the room. I tried dropping the temp and power level but it just keep feeding. I hit the power button and crawled back in bed. I will look in to it in the daylight.

Check temp sensor and external thermostat. It should have shut down if it overheats the stove. That thing has a load of sensors. Any error codes?

 

[Drew65]

No codes just burning away. I spilled pellets filling it tonight and my first thought was the thermostat wire when I was sweeping behind it. I looked and it's quite high up and looks like it's still plugged in. It was hot back their and its late but that's the first thing I'm looking at.

Was the stove set on energy saver or room temp? If it was on energy saver then when you dropped the set temp it should have flashed "energy saver ok," and started the standby process. If not using energy saver the stove should have moved to P1 and would not have fed as many pellets. Check your room temp probe. It may not have been sensing the temp correctly. If it is sensing okay then this may be a control board logic problem. Who knows if it will do it again. Try resetting the stove. Go to "menu parameters." [set]. Data bank [set]. Hold down the + sign on the temp side until you get to O0 [set] (letter O zero). This should do the trick. I think that a 1 got stuck and didn't go back to 0 in the boards processes when the temperature was reached.

Before you do this go to "menu parameters" [set] factory settings" [set] and stop at E9 [set]. There will be 28 parameters listed. Press the +- sign on the power side to advance through each setting. You should copy these down somewhere for safekeeping so you can input the numbers again after the reset. If the tech who installed the stove did not set these parameters for you when the stove was installed then you are running off of the factory settings anyway and writing down the parameters beforehand won't matter.
1st order of business, get some sleep.

It was in energy saver and running on factory settings

I'm leaning more towards the board just goofing up. It may not do it again but for peace of mind go ahead and do a reset anyway. The time and date won't have to be reset but you will have to set up your energy saver settings again.

Using the buttons on top of the stove, scroll to the end for Smoke temp, which is the temp of the flue gases as they vent. If they get too high, the stove should stop feeding and go into a blower mode, like when it's cleaning the grate. You probably already cleared your problem, but if it ever happens again, you should check the Smoke temp for confirmation.

On a tangent, I check the smoke temp regularly when I try new pellets. I figure this might be a good way to check the heat output of a pellet under similar circumstances.

I'm thinking along the lines of EastMtn, perhaps you had an energy surge that goofed your board. Is your stove protected with a surge protector or UPS?

 

[Drew65]

Yes a Tripp Lite Isoblok2-0 surge and line filter

Ok I found two things. The temp sensor is stapled to a outside wall. The installer showed me when he did that he stapled it a few inches down and let the end hang away from the wall. Well when I was cleaning up the spill it pulled the probe tight to the staple. So the stove was huffing away trying to heat up the wall behind stove. And when I checked he plug on the other end it was out a little bit. I did a reset and so far it's back to its old self

Operator error again. Smart stoves are smarter than its owners

 

[Drew65]

Lucky they are. Well smarter then me doesn't say much for the stove

Whew! I was worried there. You should set your stove to display the temperature, so that way you can see what the probe is sensing, which would alert you to cases where the probe gets dislodged. I think everyone here who has a Piazzetta has experienced the probe moving and giving a spurious reading, though nothing as serious as yours!
