Enumeration Feature

AirflowDirection (DIR)

Airflow Direction attribute is supported

Auto (AUT)

Automatic mode supported for fan speed

MultiSpeed (SPD)

Legacy Fan Control cluster revision 0-1 defined 3 speeds (low, medium and high) plus automatic speed control but left it up to the implementer to decide what was supported. Therefore, it is assumed that legacy client implementations are capable of determining, from the server, the number of speeds supported between 1, 2, or 3, and whether automatic speed control is supported.

The MultiSpeed feature includes new attributes that support a running fan speed value from 0 to SpeedMax, which has a maximum of 100.

See Speed Rules for more details.

Rocking (RCK)

Rocking movement supported

Step (STEP)

Step command supported

Wind (WND)

Wind emulation supported
