If a Fan Mode is supported the bit MUST be set to 1. If a Fan Mode is not supported the bit MUST be set to 0. It is only necessary to send the Bit Mask fields from 1 and up to the one indicating the last supported fan mode. The number of Bit Mask fields transmitted MUST be determined from the length field in the frame.
