I am wiring a Hampton Bay fan that has a remote. From the house wiring I have the following wires: Red, Black, white and green. The Hampton Bay remote only has white and black wire in puts. What do I do with the house red wire? (The original fan had 2 wall switches, one for the light and one for the fan)

I am pasting in my answer to a similar problem.

Everything needs to be connected connected back just as it was. There are a number of ways to connect up 2 switches to a load. They all use double pole switches and 3 conductor cables plus ground to connect them. Unfortunately no real electrician feels compelled to do it the same way anybody else does it.

If there is only one, 3 conductor cable at the fan, it is possible the red wire wasn't used. Has it been stripped, and bent into a hook or twisted with another wire? If not, try not connecting it.

If you have both a 2 conductor and a 3 conductor cable, connect the red wire to the fan, and the 2 black wires together. Connect all the white wires together. Depending how things are wired, this may not work. You might try disconnecting everything except the white wires, and trying the switches in different positions and use a test light or meter to see if things work.

If this does not match you wiring, or you can't make it work, try finding a diagram for 3 way switches. You can also post back explaining what wires you have at the fan.

In your case, the green wire is the ground. It should be fastened to the case of the fan or to the box that supports the fan.
