# fanSpeedPercentage

A floating-point value indicating the requested fan speed specified as a percentage of the maximum speed.

```
@nonobjc final var fanSpeedPercentage: Double? { get }
```

## Discussion

Convert the value in this property to an appropriate fan speed setting in your vehicle. For example, if the user asks to set the fan speed to 50%, select a fan speed halfway between the minimum and maximum values.

This property is `nil` when the user modified a different climate control setting.
