Thanks for the previous answer. I located a wiring diagram - but it was helpful. Now I'm looking at the CAM-STAT FAL7C-15T-110-220 controller, and would like to know how to adjust it. It indicates that the Fan OFF is to be 100°, and it appears that is correctly set. Then online it indicates Set Fan Differential to -A.. . I can't locate that, and the Set Limit should be 200°. The latter two are not well described as to how that is done. Any information there? Thanks again.
