Zusammenfassung:	A method for controlling a transport refrigeration system (TRS) for refrigeration of a transport unit is disclosed. The TRS includes a TRS controller connected to the TRS for operating the TRS, a eutectic device including a eutectic medium, a transport refrigeration unit (TRU) having a refrigerant circuit for directing a refrigerant fluid there through, and a cooling fluid circuit in thermal contact with the eutectic medium for directing a cooling fluid to be in thermal contact with the eutectic medium. The method includes the TRS controller receiving a selection of a cooling mode for the TRS, and cooling an inside of a transport unit according to the cooling mode selected. The cooling includes one or more of a first cooling type and a second cooling type. The cooling mode for the TRS includes a manual cooling mode, a local automatic cooling mode, a dynamic cooling mode, and a preset cooling mode.
