This communication object is used to control the fan speed of the corresponding indoor
unit in the VRV system and obtain feedback on the current fan speed state of the VRV
indoor unit. Each fan speed, including the value corresponding to the automatic fan speed,
can be set in the "VRV Function-Fan" parameter page. The VRV page belongs to the
subordinate thermostat, so the request is the output object, and the confirmation is the
