Thewall controller remains active as a display so that fault messages can still be viewed, and toggling between output frequency and fanRPM 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 shownabove.About I/O Mode SelectionBig Ass Fans factory defaults for analog and digital inputs are ACI (4-20 mA) and NPN (inputs pulled down to DC Common).
