Terry,
Is your set up working? I've got no working fans, and it's making me crazy. I've gone through this thread and the one on Lat-g several times today trying to figure out what I've done wrong, but I sure can't figure out any thing.
Wiring
pwm wire from #6 on the controller to J3-49. Check.
Fused power to pin #3 on the controller. Check.
Ground from pin #2 on the controller. Check.
Fan ground to pin #1 on the controller. Check.
Fan power to pin #4 on the controller. Check.
Programming
Modify Fan to PWM Electric, running at 128 Hz.
Add values to Fan Desired % vs ECT table.
Add values to Fan Desired % vs AC pressure table.
