Talking about my Harman XXV. Ok so on any given day running in room temp manual fan on high and heat control all the way up I come up with a maximum temperature whatever it may be it is as warm as it will get the room. If I switch to stove temp Auto with the fan and heat control all the way up the room will get warmer . So my conclusion being that stove temp auto throws more heat than room temp manual. Possibly a few more pellets being used but who cares.
