Any electrician-minded people on here (ceiling fan connection help)

[forgop]

Ok, my current set up is a 2 wall switch-a light with dimmer and a separate control for the fan with a speed selector.

I removed my old fan and have a red, white, black, and a ground wire coming out of the outlet box. My new fan will have a remote. The instructions state to make the following connections:

Outlet Box White-Connect to AC in N from wire receiver
Outlet Box Red-Connect to AC in L from wire receiver
Outlet Box Black-(NOT MENTIONED)
Outlet Box Ground-connect to 2 green wires on hanger bracket and hanger ball

I've made the black/blue/white connections from the receiver to the fan as instructed, but I'm puzzled as to how to make all of the outlet box connections to the receiver. Where does the black wire go?

While I'm asking another stupid question, my brother thinks this connection will only allow the light/fan to come on with the use of the remote. Is that true?

Thanks!
