I have been running my P61 in stove temp because I thought it was just easier. I noticed I was going through a lot of pellets even just running on stove temp 2. I read that room temp is more efficient so I got the thermostat probe out and hooked it up. All I can say is wow I wish I hooked this thing up a month ago. It was always either too hot or too cold before. Now Ive got a temp of 77 where the stove is and 72 on the second floor where the bedrooms are. It has stayed this exact temp for 12 hours. No more messing with the stove settings. Love it!
