Fan Speed

Use the fan speed increase/decrease knob in order to manually change the fan speed in the following manner:
^ Turning the fan speed knob 1 detent in a clockwise direction increases the fan speed by 1 level.
^ Turning the fan speed knob 1 detent in a counterclockwise direction decreases the fan speed by 1 level.
^ Turning the fan speed knob all the way will increase/decrease the fan speed to the maximum.

If the system is operating under AUTO fan speed control, turning the fan speed knob in either direction stops the AUTO fan speed control and begins a manual fan speed control.

The fan speed remains constant, unless the driver turns the speed control knob again.

When the system is in OFF mode, turning the fan speed knob in a clockwise direction causes the system to turn on AUTO mode with AUTO fan speed control.
