Wall Controller Operation
Upon initial power-up of the fan, the wall controller display appears as shown on the
right. The wall controller is programmed to show the fan’s current running speed in
RPM on the LED display. The display also indicates if the fan is stopped (STOP), set to
run forward (FWD), or is set to respond to a remote control source (REM) such as an
Energy Management System or Building Automation System.
Other main LED display modes include Motor Current, Memory Status, Motor Command
Frequency, and Motor Actual Frequency. Useful indicators of fan status on the wall
controller are RUN/STOP, JOG, FWD/REV direction, and External or Local Control.
To operate the fan from the wall controller,
press the LOCAL/REM button to make
sure that the LOC indicator is illuminated. The RUN, STOP, and FWD/REV buttons are
functional only when the LOC indicator is illuminated.
Note: To access the LOCAL/REM
button on the controller, the controller cover must be removed.
For error code definitions and corrective actions, see "Fan Error Codes" on page 48.

Starting, stopping, and direction control
The LOC indicator must be illuminated on the fan controller in order to start, stop, or
change the direction of the fan.
Note: The RUN, STOP/RESET, and FWD/REV buttons
are disabled while External Automation Control is enabled (REM LED illuminated).
To start the fan,
press the RUN button on the controller’s display. When
the RUN button is pressed, the STOP LED extinguishes and the RUN
LED illuminates while the fan accelerates to the commanded speed.
To decelerate the fan,
press the STOP/RESET button. The RUN LED
will flash, indicating that the fan controller has accepted the command,
and the STOP LED will illuminate.
Proper fan rotation is initially set at the factory.
To reverse the rotation of the fan,
press the FWD/REV button. The fan
does not have to be stopped in order to perform this action. When pressed while the fan is running, the FWD or REV
LED will flash (current direction), indicating a pending change in fan direction.

Changing the fan speed
The LOC indicator must be illuminated to adjust fan speed, which can be performed when the fan is stopped or running.
To change the fan speed,
press the UP and DOWN arrow buttons. The fan speed can be adjusted
regardless of what is visible on the LED display, with the exception of the Memory Read/Write screen.
When one of the direction keys is pressed, the current display mode is forced to change to the Fan
Freq. Command screen as shown below.
Note: To accelerate this process, press either the LEFT or RIGHT arrow button to select which digit is controlled by the UP and DOWN
buttons. Allowing selection of the digit can make changing the fan speed a very fast or very accurate operation. The controller cover
must be removed in order to access the LEFT and RIGHT arrow buttons
