What do you mean by 1 rotation? The auger is actuated by 2 things the timer which will rotate the auger to preset time or the honeywell controller by preset temperature. Turn your caps off we hear you just fine :P

What are your separate components in your wiring?

You have a timer, triple aquastat, and stoker motor. What else?
