Just installed a new control board on my accentra and the variable speed setting on the room temp/stove temp switch doesnt seem like its working different compared to my older board. I have it set in the middle and the fan blows really low during a large fire and never speeds up to high. On my old board with a very large fire in the middle setting it blew on high. Just wondering if that is how the new boards are or is something wrong? Really have nothing to compare to so any new harman owners with the new board please chime in. If i turn switch to high it will blow on high.
