Fan Speed

Use the fan speed button in order to manually change the fan speed in the following manner:
^ Pressing the fan speed button once increases/decreases the fan speed by 1 level.
^ Holding the fan speed button will increase/decrease the fan speed to the maximum.

If the system is operating under AUTO fan speed control, pressing the fan speed button stops the AUTO fan speed control and begins a manual fan speed control.

The fan speed remains constant, unless the driver presses the speed control button or the AUTO button.

When the system is in OFF mode, pressing the AUTO button causes the system to turn on AUTO mode with AUTO fan speed control.
