A method for controlling a fiber management apparatus that comprises a washing unit and a drying unit operated by a single operation unit , and are remotely controlled by an external signal to manage hygiene of the drying unit , the method comprising: setting (S110) a hygiene management mode of the drying unit according to the external signal; selecting (S120) synchronization or non-synchronization of a completion time between a washing operation of the washing unit and a hygienic operation of the drying unit according to the external signal; activating a control module of the drying unit and interoperably connecting (S130) the washing unit with the drying unit when power is applied to the washing unit ; performing (S140), by the drying unit (S120), the hygienic operation corresponding to a first scenario according to a result of the selection or a second scenario according to a result of the selection; and performing (S160), by the drying unit , a plurality of actions corresponding to a plurality of unexpected situations when the plurality of unexpected situations occurs in the washing unit , wherein the plurality of unexpected situations comprises a situation in which the operation of the washing unit is suddenly stopped during operation, wherein the hygienic operation is an operation of sterilizing and washing the drying unit , wherein the first scenario is that the drying unit performs the hygienic operation when the synchronization is selected, and wherein the second scenario is that the drying unit performs the hygienic operation when the non-synchronization is selected, and characterized in that the hygienic operation of the drying unit is completed at the same time or earlier than the washing operation of the washing unit when the first scenario is performed. setting (S110) a hygiene management mode of the drying unit according to the external signal; selecting (S120) synchronization or non-synchronization of a completion time between a washing operation of the washing unit and a hygienic operation of the drying unit according to the external signal; activating a control module of the drying unit and interoperably connecting (S130) the washing unit with the drying unit when power is applied to the washing unit ; performing (S140), by the drying unit (S120), the hygienic operation corresponding to a first scenario according to a result of the selection or a second scenario according to a result of the selection; and performing (S160), by the drying unit , a plurality of actions corresponding to a plurality of unexpected situations when the plurality of unexpected situations occurs in the washing unit , wherein the plurality of unexpected situations comprises a situation in which the operation of the washing unit is suddenly stopped during operation, wherein the hygienic operation is an operation of sterilizing and washing the drying unit , wherein the first scenario is that the drying unit performs the hygienic operation when the synchronization is selected, and wherein the second scenario is that the drying unit performs the hygienic operation when the non-synchronization is selected, and characterized in that the hygienic operation of the drying unit is completed at the same time or earlier than the washing operation of the washing unit when the first scenario is performed. <EOS>
