  • The QC-4770, like all of the "Classic Line" fans (except for the QC-1500) have the optional capability of having the motors being wired for two speeds. For two speed operation, your installer would need to simply remove the included 8ft. power cord and run a 3rd wire from the fan motor to the 3-wire wall switch and timer. If using a remote system or standard on/off wall switch, the fan will work perfectly as a single speed fan (as set in the factory)
  • The ideal setup for automatic operation, is to have your electrician hardwire the fan to a wall timer and standard off/on or 3 way switch (if wired for 2 speed operation) mounted next to each other on the wall at a central location such as a common hallway
  • This allows you to turn the fans off based on the time set on the timer or put the timer on hold and use the multiple wall switches to operate your fans individually. This method of installation gives your the flexibility of operating one or more fans during cooler months when you may not want all of your fans running at the same time
