Min Feed

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

Is the min feed controlled by the max setpoint? Right now I am running my LL controlled only by the min feed with thermostat set at 58 degrees. I just upgraded to the new software and I see it changed my min feed some.

Thanks, Stan

That pretty much controls the IDLE burn. Don't set it too low, you might loose the fire. I think mine is about 8 or 10, when it's warmer to make more heat to pull more draft in the chimney. Typically MIN 6-8 is good for the LL stoves.

The MAX is when you are calling for heat and your FR (Feed Rate) is at 99%, you should NOT be pushing hot coals off the grate. If so, the max has to come down a couple points.

Always make small adjustments and let the stove settle for an hour or more before making any more adjustments. a couple points at a time. :)

They both are the ON/OFF times or percentages (%). I think Min 6 (secs on), MAX 50 (Seconds off) or something like that.

Nice info but it did not answer my question.
Thanks, Stan

To answer you directly - I think so. I am doing exactly what you are doing on my AnthraKing (or Pocono). I have MIN set at 2 and have lowered my thermostat also. During this mild weather if I want a tiny bit of warmth I raise my MAX to 4 or 6. It gives unique control using every little coal. My thermostat is set at 67F and max set at 18. If the room drops below 67F unexpectedly then MAX kicks in but only gently. So I set MAX and MIN according to the weather.

MILD, MIN 2 and MAX 18 and thermostat (D and N) 67F

Getting there, MIN 6 and MAX 24 and thermostat (D 71F and 69F)

BTTW (where TTW is to the wall), MIN=6 or 8 and MAX 40 or so. and thermostat (D 73F and N 70F)

Works well for me and stops big swings. However, be advised that is not (apparently) what LL or coal-trol recommend so I don't use set backs. Your mileage may vary and you should consult higher authorities..

Got messed up a little - this should read

To answer you directly - I don't think so. Doesn't say MIN=2 relate to feed motor is going 2% of the time?
