Re: Contour Fan + flex a lite controller question
I'm running something similar,(Windstar fan). The 2 speed fan has 3 wires, one is a ground, the other 2 control the speed. Power to one wire is slow speed, power to 2 is high speed, so yes you need to connect them both to the power output on the controller. Also the controller has a soft start so it will pull a lower amperage when it starts the fan, about 40 percent less amp spike when it first turns on.
