hello all, this is my first post on this site so if I'm in the wrong place with this I'm sorry. I'm about 75% done building a new wood gasifacion boiler and trying to find a controller to handle the fan and water temp. .I want to have the fan startup to ramp up not just start at full power and slow down when close to upper temp. I was looking at a rk2001ua but don't know if it's what I need or not. This is the second boiler I've built. The first one burns coal and is controlled from an aquastat.So the find comes on and off at full speed. Any helpfull idea's?
