Installing New Vent Fan in Bathroom

My new vent fan (heat, light, and fan) in the bathroom includes two (2) white wires, a black, a green, a blue, and a red. However, the old vent I'm replacing had five white cables ( a ground, a black and white ) connected to it. Three of the white cables come from the switches in the bathroom. Two of the white cables come from the electrical source. Any suggestions on how I should wire these all together? See image.

Re: Installing New Vent Fan in Bathroom

Pregan, by Code green (ground) is always connected to the frame, other green wires and/or bare wires.

White wires (neutral) are always connected to other white wires, unless the previous electrician has re-identified them with a piece of colored tape.

Other colors black, red, etc are called "hot" and will measure 120V in relation to the neutral or ground.

I personally wire the (black) or red) power wires to one side of the switches and connect the other side of switches to the lights and fans. This is not Code and is left to the electrician's discretion.

Because of this, your question is very hard to answer, without testing the circuit.
