Follow up questions from threads a few weeks ago..
I have a pellet stove with an auger motor controlled by a Timer/Potentiometer combination which cycles the motor on and off.
The motor "on" cylce is a constant three seconds regardless of the Potentiometer setting.
What does change with the pot dial setting is the delay period between auger motor "on" cycles.
I have not been able to understand clearly how this happens.
I understand the pot is reducing the current flow to some timer component as it is dialed up, but so what? How does varied current through the pot translate to shorter/longer delay periods on the motor? I see how the motor could cycle on and off via a time delay relay, but wouldn't that mean a uniform off period, not a vaired one.? I know the pot is somehow varying the off period and that is the part that is over this beginner's head.
thanks again to one and all for sharing your knowledge, scott
