Don't want to be a pain but could not find the answer in the long M55 thread. So I understand that in Auto/Off...if the T-stat reaches temp and there is no call for heat approx 30 min later then the stove shuts off untill the room cools and the T-stat calls for heat again. Hi/Lo never shuts off, it just goes Hi/lo....? So, arn't the two settings doing the exact same thing...ging from high to lo....its just that (Auto/Off) has the ability to shut down if the room temps stay at temperature! Thanks, Bill
