The Powerfoil X2.0 fan is also programmed to be controlled by an Energy Management System or Building Automation System.

Starting, stopping, and speed control duties are handled by the distributed I/O (2 N.O. contacts, 1 analog) provided by the installer. The
wall controller remains active as a display so that fault messages can still be viewed, and toggling between output frequency and fan
RPM displays can still be performed. This mode of operation is commonly referred to as "external control."
*For distributed I/O to be active, the REM indicator light must be illuminated by pressing the LOCAL/REM button as shown
above.
About I/O Mode Selection
Big Ass Fans factory defaults for analog and digital inputs are ACI (4-20 mA) and NPN (inputs pulled down to DC Common). If required,
these may be switched to AVI (0-10 VDC as shown above) and PNP (inputs pulled up to 24 VDC) via the dip switches shown above. If
required, a diagram can be provided to reflect these alternate connection schemes.
