How to Put Broan 164 Vent/Light and Heater on Separate Switches 

Thank you for your feedback. Unfortunately, we do not have a video for that control option at this time. There is a diagram for a 3-function control in the installation manual on page 5.

@@motoxjosh29 We are sorry to hear this diagram is not helpful to you. Please call our Technical Support Team at 800-637-1453 so that we can assist you directly.

Thank you for your question regarding the model 164. You can install a timer for the heaters. You would not be able to control the fan and heater with the humidity sensor. We would recommend contacting our Product Support directly at 800-637-1453 so we can go over your intentions and provide you with the proper information. We look forward to your call!

Thank you for your question regarding the 164 bulb heater. This model should be connected to 120 volts.

Thank you for your question. This unit is designed for supplemental heat only and should not be relied upon as the primary heat source for a room. If you would like to discuss your application with a member of our team, please call our Product Support Team at 800-637-1453 for assistance.

Thank you for your question on the model 164. If you want each function to operate separately, you would have one switch leg to the red wire (light), one switch leg to the black wire for the second light (heat), and one switch leg to the blue wire (fan). The yellow wire is for the thermostat and would need to be hard-wired separately for constant power. All the white wires get tied together. If you need more help, please give our Product Support team a call at 800-637-1453.

Thank you for your inquiry. Here is the installation manual for this unit, the wiring for controls is on page 5: www.broan-nutone.com/getmedia/b4e2c1d1-c8fc-47f0-aef7-d6f2acd4ad32/Installation-Guide-161-162-163-164.pdf?ext=.pdf We also have a product support Team available at 800-637-1453 that would be happy to assist with your questions.

Thank you for your question regarding the 164-bulb heater and fan unit. Yes, the ventilation fan feature should be ducted to the outside.

Thank you for reaching out. According to our Product Support Team, you can use 14-3 wire. Please call our Product Support Team at 800-637-1453 if we can be of future assistance.

Thank you for your comments. We are sorry to hear this was not the wiring assistance you are hoping to see. Unfortunately, we do not have a video for that control option at this time.

Thank you for your comment on the 765H80L heater, fan, and light unit. Yes, this model must be installed on a separate 20-amp circuit. Use a 12 gauge power cable that meets local codes.

The red, blue, black, yellow, and two white wires will be visible when accessing the junction box. Please contact our Product Support team if you need more assistance at 800-637-1453. We will be happy to walk through the product with you and answer any questions you may have.

Thank you for your inquiry. This does not have the same wiring harness. You would need to replace the unit completely to use the BHF80 (non-lighted unit) or the BHFLED80 (lighted model). If you have additional specification, application or installation questions, please call our Product Support Team directly at 800-637-1453.

I'm returning the replacement BHF80 to the big box stoe. I can't get to the brackets in the ceiling without taking the drywall out so I'm purchasing the replacement heater unit to go into the existing box. The heater is different in the BHF80 than in the broken one. @@BroanNuToneLLC
