I have a light switch that has two switches on it. One to control the fan and one to control the light. I'm reading the direction on how to wire it, and it calls for using a red wire. I'm not sure what that means. Can you help me? I'm using 12-2 wiring. It has black, white and ground.

Answer:
Thank you for your question on the 680 exhaust fan/light. You would connect the bare ground wire from the house to the ground screw in the unit housing. You would connect the two white wires from the 680 to the white neutral wires from the house. You would connect the blue wire (light power wire) from the 680 to the hot power wire from your light switch. You would connect the black wire (exhaust fan power wire) from the 680 to the hot power wire from the fan switch. If you have additional questions, please call our Technical Support group at 800-637-1453

I need more ventilation than my 678 is providing. Can I purchase a 680 fan/motor assembly and install it into the 678 fan box?

Thank you for your question. I do not see a retrofit assembly, please Call Technical Support at 1-800-637-1453 with the letter suffix (678-A-B-C-D-E –ETC). This is needed to know if there is anything to match your housing.

Answer:
Thank you for your question on the model 678 exhaust fan light. I’m sorry, but the only bulb we recommend for this unit is a 100 watt maximum incandescent bulb.

Thank you for your question. Yes, your ceiling fan can be surrounded by insulation. Broan bath fans are designed to provide adequate cooling for motors and lighting.

Answers
Answer:
The new model 678 fan/light cannot be installed from the room. The extended brackets on the old housing are above the ceiling material and are not visible to the customer unless you go into the attic. A consumer would have to pry the screws or nails loose from ceiling joists or framing in the attic. Also, you cannot attach duct and electrical wiring from the room like you can on units like our new Ultra series.
Another option you have to repair your pre-2000 unit is to buy a replacement motor and wheel or fan assembly that can be put up in the existing housing without disturbing the installation. Please contact Broan Customer Service at 1-800-558-1711.
