Hello, I have been running my Alaska 140 dual paddle feed for 4 years now without a fan switch. I see they now come with that as an option. I installed one, but did not yet wire it. My question is when the stove is running low plenum temp only drops to 88 and fan off it will max out at 105. It dosent make much sense to use a fan switch with the stove on low. I would guess that would be the point of having a manual override. What settings do you use when it's colder out and the stove is running harder?
