The invention relates to a method for configuring, on a control unit, operating parameters of a plurality of devices of a refrigeration system. A user selects on the control unit, among the plurality of devices of the refrigeration system, a first device to configure. Information of valid configurable operating parameters of the first device is provided on the control unit. The user selects at least one of the valid configurable operating parameters of the first device, thereby configuring the first device. Information stored about operating parameters of other devices of the refrigeration system, based on the configuration of the first device, is then provided on the control unit. Finally, the user confirms, on the control unit, one or more operating parameters of one or more of the other devices, thereby configuring the one or more other devices. The invention also relates to a control unit and a refrigeration system.
