Thanks for the replies Mike.
1) Turn the breaker to OFF. Look at the two wires spliced onto the dimmer switch. One of the colors leaving the dimmer switch should either be red or brown then. That color will be the switched loop wire leaving the dimmer switch. It is only hot when the dimmer switch is activated. Sounds then like the red wire is the switched loop conductor leaving the dimmer switch then. You can confirm if the brown is a constant hot wire using a voltage tester.
The receiver will have 3 wires for the LINE side or power feed side, ie, black, white and green. The receiver black gets connected to the ceiling hot (red or brown), Receiver white gets connected to ceiling box white. Greens get connected together.
The receiver out or LOAD side will have 1 blue, 1 back and 1 white. Blue gets connected to the blue on the fan for the light kit. Black to black for the fan motor, white to white for the neutrals and green to green for grounds.
If the brown is a constant hot wire, the remote receiver black will connect to the brown, white to white on the receiver and green to green.
2) DO NOT connect the fan motor to the dimmer switch. A dimmer switch will eventually destroy the fan motor.
Ceiling fans require a separate 3 speed wall switch that is rated only for ceiling fans or using the pull chains if hard-wired and not using a remote.
3) Since you will be connecting a remote control to control the fan and light kit, there is no need for a wall switch, unless you want to install a single pole single throw wall switch in place of the dimmer to completely turn the fan/light kit OFF ad over-ride the remote. If so, the dimmer needs to be removed and replaced with a regular ON/OFF snap switch.
