Kiln fan settings

Guidelines for setting thermostatically controlled fans in lumber kilns. March 3, 2000

I may have made a mistake but here it is. I installed a thermostatic fan in my kiln. At what temperature should I set it to turn on. The range is from 55 to 140 degrees F. The wood is Pennsylvania red oak.

Set it for about 25 degrees F hotter than the expected morning low temperature; when the lumber is real wet, 15 degrees F is O.K.
