I have a Harmon pc-45 stove and have been experimenting with the dip switch settings on the control panel. This all started when I purchased the Optimizer kit 1-00-06801 to run pellets. This has you adjusting dip switches 1,2,7 and 8 to the on position and 3,4,5 and 6 to the off position. The problem is under these settings I go through a lot of pellets and I seem to get a error, "6 blinking light code" more than usual. I seem to know what switches 1 & 2 do but what do the other switches control?
