CAUTION: The fan must operate on a dedicated 
circuit with a dedicated neutral. Failure to install 
the fan on a dedicated circuit will cause the fan 
to operate improperly.
Illustrated on the right is a typical lighting circuit with 
one basic light switch. The fan operational critical 
red conductor or “traveler” conductor is absent. For 
Isis fan applications in which installing a 3-wire plus 
ground circuit (black, white, and red) is impractical or 
impossible, an optional limited access fan controller 
can be installed to eliminate the required red traveler 
conductor between the controller and the fan, allowing 
the utilization of the existing 2-wire plus ground circuit 
(black and white) shown below.
Note: This scenario is common in residences in which 
only a light circuit was previously installed.
Typical Lighting Circuit
Note: It is essential that the speed controller and remote controller are 
installed on a common branch circuit. The control signal between the 
devices is modulated on the shared hot conductor and may be absorbed 
at the breaker panel if this rule is not followed. This wiring method 
should have been noted at the time of order. If not, contact Big Ass Fans 
Customer Service.
