The remote controller displays the fan speed on a scale of 1 to 4.
For the 16 steps fan speed by the automatic fan speed control:
During 25 to 45% fan speed operation, it displays the fan speed on a scale of 1.
During 50 to 70% fan speed operation, it displays the fan speed on a scale of 1 and 2.
During 75 to 95% fan speed operation, it displays the fan speed on a scale of 1 to 3.
During 100% fan speed operation, it displays the airflow on a scale of 1 to 4.
