Hi, took out a bad heater/fan/light fixture and installing a new one. the old one was a major pain to remove and in the process, i can't remember how they had it wired. there are 3 switches but only 2 12/2 wires going to the fixture. The instructions talk about a red wire that I don't have. I have put a tester to the wires and that only accounts for 2 of the switches (heater#1 and the fan#2) am I over thinking this? How do I get the light to work too?

The black and white wires I'm pointing to are dead.

My switchs and wires. There is an extra black and white wire but they're dead.

The original install cheated. You need a meter or tester to determine which white wire is your neutral, the remaining white and 2 blacks will be your 3 switched legs. Ideally, and to comply with code, you should have a 12/2 and a 12/3 as shown on your new unit's schematic.

The model 655 is a noisey fan. The 4.0 sone rating disqualifies it in my mind, particularly when it is only 70 CFM.

Unless budget was your driving factor, I would suggest taking it back and selecting a quieter unit.

You need two 12/2 cables. What works even better is a length of 12/2/2 wire (4 insulated conductors plus a bare ground). You need three hot wires, and you can re-mark the red/white wire with a blue sharpie.

Also, this unit need to be entirely on a separate 20-amp circuit.
