The Quiet Cool QC-2250 Whole House Fan
When you purchase a QC-2250 whole house fan from us, you get a complete system, which includes the fan, ducting, damper and grille. All that it needed for installation is your choice of controls.
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 8' 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). Consult with your electrician about wiring this 2 speed wiring option.
This 2 speed option would actually make our dual motor QC-4500 and QC-6400 fans 4 speed capable because these fans have two motors per fan.
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.
For those that plan on mounting the fan grille on a side wall instead of the ceiling, (often done on a room with a vaulted ceiling), you will need one optional wall adaptor per fan.
