Update
Have burned no wood for three weeks now. Have gotten the hang of the coal routine. Fan off, shake, empty ash pan daily, fan on, forget it. Still loading 2x a day. Will likely use 1 ton of coal per month in average temps. Johnson A419 controller set at 180°, 2° differential. Have installed a Maverick ET-732 barbeque remote temp sensor. Now I can watch temps from the house.
Next project is an ambient temperature sensor that will use the A419s offset feature. It will offset the set point to 160° when ambient temp is above 55°. I also need to clean up the install, it looks like a rat's nest inside the stove back. Maybe a nice box to mount everytnig in...hmmmm...
Enough for now, off to cut wood!
