It should feed exactly the same amount of pellets whether you hit reset or the thermostat starts it since you are resetting the auger timer. The green light tells you that you got to 200 degrees and it tells the auger circuit to start feeding pellets at intervals. If you have a decent flame, it should turn to red indicating that it got to 600 degrees, which shuts off the igniter if its timer hasn't done that already.The stove is in the finished basement/game room so I'm always near it. I'll let it cool and try it dead cold again but if memory serves the Reset starts works every time because it feeds more pellets initially than when it starts via thermostat turning on.
I am stumped! (not much help )
