		* floatValues[0] = the requested value that an application wants to set a temperature to.
		* floatValues[1] = the unit for floatValues[0]. It should be one of

		* floatValues[3] = the value OEMs suggested in FAHRENHEIT. This value is not included

		*
		* An application calls set(VehiclePropValue propValue) with the requested value and unit for
		* the value. OEMs need to return the suggested values in floatValues[2] and floatValues[3] by
		* onPropertyEvent() callbacks.
		*
		* For example, when a user uses the voice assistant to set HVAC temperature to 66.2 in
		* Fahrenheit.
		* First, an application will set this property with the value
		* [66.2, (float)VehicleUnit:FAHRENHEIT,0,0].
		* If OEMs suggest to set 19.0 in Celsius or 66.5 in Fahrenheit for user's request, then VHAL
		* must generate a callback with property value
		* [66.2, (float)VehicleUnit:FAHRENHEIT, 19.0, 66.5]. After the voice assistant gets the
		* callback, it will inform the user and set HVAC temperature to the suggested value.
		*
		* Another example, an application receives 21 Celsius as the current temperature value by
		* querying HVC_TEMPERATURE_SET. But the application wants to know what value is displayed on
		* the car's UI in Fahrenheit.
		* For this, the application sets the property to [21, (float)VehicleUnit:CELSIUS, 0, 0]. If
		* the suggested value by the OEM for 21 Celsius is 70 Fahrenheit, then VHAL must generate a
		* callback with property value [21, (float)VehicleUnit:CELSIUS, 21.0, 70.0].
		* In this case, the application can know that the value is 70.0 Fahrenheit in the car’s UI.
