Congratulation Davies-Crag, it sure was nice to have a product, especially a fan controller work out of box. It is nice it shows what the probe is reading on the digital display and actually start where it is supposed to. I have it set as fan one is the low setting, comes on at 70C, then 10 seconds later high fans kick as fan two. The turn off at 65 and kick on again at 70 degrees, a very nice and highly rated product.
