I am giving this a 3 star review. Once installed - it works, the install process and technical design gets a negative 2 star. The design of this thing is an exercise in over complexity.  The fan this is replacing had all the same features and you connected exactly 3 wires (it is nearly 20 years old too). But this one because the "remote receiver" is a separate module that you have to wire in manually you have 8. Then you have to stuff all those wire nuts and wire into a cover that will barely hold it (even after you cut off the 3 feet of excess wire). you will also want to make sure you have a short 90 degree screw driver or you may never get the cover screws in. If it weren't so much trouble to send it back I would.
