The company pretty much uses the same controller-circuit board for all stoves. Does the auger run on a timer? Or does the auger run off a temp sensor? Have only had king 5502m for this winter. Only used lignetics green Supreme. Trying hamers hot ones today.

The controller-circuit boards look the same but they are programed different, you can not switch boards between pellet stove models. Your 5502m is programed to run the auger based on the heat setting you chose. USSC uses feed rates based on pounds per hour. Some boards only have heat settings 1-3 some 1-5 and some 1-9 each setting will make the auger turn for so many seconds and then stop for so many seconds. So you could say the auger is run on a digital timer based on the heat range you chose.

The temp sensor (thermitor) on your stove does control the shut down mode, if the stove does not reach 110 degrees in around 23 minutes stove will go into shut down mode and give you error code for no fire if the stove reaches 450 degrees the stove will go into shut down mode and give you a error code for over heat. The temp sensor also controls when you room fan comes on it should be around 130 degrees.

From manual:
Your pellet stove utilizes a inclined auger fuel feed system that is operated by a microprocessor controlled digital circuit
board. The digital circuit board allows the inclined auger fuel feed system to run in a timer-based, non-continuous cycle;
this cycling allows the auger to run for a predetermined period of seconds. The auger pushes pellets up a chute located
at the front/bottom of the hopper which in turn falls through another chute into the burnpot. Your stove is equipped with
an automatic ignition system that should ignite the fuel within 5-10 minutes from pressing the ON button. As pellets
enter the burn pot and ignite, outside air is drawn across the fuel and heated during the combustion process which is
then pulled through the heat exchanger by the exhaust motor or draft fan. As the stove heats up, room air is circulated
around the heat exchanger by means of a room air blower, distributing warm air into the room.
The amount of heat produced by the stove is proportional to the rate of the fuel that is burned, and this rate is controlled
by the “HEAT RANGE” setting. In order to maintain combustion of the fuel at a desired rate, the air provided to the burn
chamber by the exhaust or draft fan must be maintained precisely. Too little air will result in a flame that is non-energetic
or lazy. If the fuel continues to flow with too little air for long enough, the burn pot will fill with too much fuel and the fire
will smother out. To much air will result in a flame that is overactive or aggressive. The flame in this situation is typically
very blue at the bottom and resembles a blow torch. If this situation continues, the fuel in the burn pot will be consumed
and the fire will go out.

I second what ARC said. My stove has 3 heat settings. You can go in and program the pellet pph for your low and high heat settings. The ones in between are automatically figured based on that.

I have my low at 1.6 pph and my high at 5pph.

There are also quite a few other perimeters that you can adjust. If you look in the USSC sticky thread you will find technical manuals that describe the process.

Is there something specific you are trying to accomplish or an issue you are trying to resolve?
