Just making sure I understand its operation..
The idle & High settings are just a timed event, the control does not increase or decrease auger speed, its at a continuous 2rpm,
The idle is timed from 1 ~ ?? and when the T Stat calls for heat it goes to high setting of 5 ~ ?? ( 1 & 5 being the standard settings)
So the control just extends the auger run time to whatever your setting are..
If this is the case, does anyone know the approximate timer increments to number position ???
