Burning Hunk
Yeah, I never got a good answer as to why, so I disregarded that advise to leave feed rate around 3-4. I run it there when it is colder, but with the mild start to winter, 3-4 makes it too warm in the house.This I think is a good example of being the generic Harman crowd consensus. I guess many just revert to the old ways because that's just the way it is, has been, and should be ideology. Fine, but I disagree with what you were told by both the shop and installer. I think many realize that feed rate 3 - 4 is a general cover all mode to run so they recommend that for a cover the butt type general rule of thumb. Sure it works pretty well but is it the best case at all times? Nope. Not here anyway.
Ask your dealer and / or tech, Then why does my stove have lower settings? I bet you get a weird look along with a blank stare while they try to think of some BS that seems to sound half way logical to them. They will be talking in circles or not have any good explanation other than 'this is what Harman recommends.' OK, with that said doctors like to hit the go to solve all antibiotics for many bacteria type ailments. Kind of a general solve it all remedy.
Now if you are not sick and have no baterial infection etc; are you going to take them. No, and not everyone is running the same fever per se.
