This fall, when I started the machine up without ashes on the ash sensor was registering temps that I had never seen in the 3 years I had used the AHS. It reached into the high 450F. I had never seen it get above 225F ever. Turns out that it takes a couple of days to have the coal burn down to the grate and get the asher functioning at lower temps.

Combustion air supply "fan in a can" kicks on when the blower kicks on.
About what I get in ash in 2 days, burning blackshak bagged.
The low triggers the dump zone and so does the secondary backup set at 200F.
I tuned the low so that when the water temp gets to 160 it kicks on the blower and it usually runs about 5-10 minutes and by then the water temp is around 180F.
I can tell you that if you're going to reburn the extras put in thru the viewport and not in the hopper I caused my one and only out fire so far by doing just that and it created bridging in the neck of the hopper.
The ash bucket was filled to nearly overflowing with un-burnt coal.
.Do you think that a low temperature dump zone that is set up to open and call for heat whenever the boiler gets down to 160 degrees

I guess if you were dumping the heat somewhere it would reduce your water temp and then kick on.
How about storing some in an indirect tank? or Do you have a pool, how about a heat exchanger?
Why doesn't your low kick on when your boiler gets bellow 160F?.
I know there is a couple different ways to wire the aquastat.
