Method for setting functional parameters of a controller of a refrigeration apparatus (101, 102, 103), comprising the steps of: - preparing a controller configured to operate a refrigeration apparatus (101, 102, 103) selected from among a plurality of refrigeration apparatuses belonging to a predefined group; a unique identifier being associated with each of said refrigeration apparatus; said controller having a set of settable functional parameters, said set comprising a plurality of subsets of functional parameters, each of said subsets being associated with one of said identifiers so as to be specifically designed for operation of the refrigeration apparatus (101, 102, 103) identified by said identifier; said controller being able to record one of said identifiers; said method being characterized in that it further comprises the steps of: - preparing a setting device provided with a primary application configured to set each of the functional parameters of said set and provided with a user interface via which said primary application may be operated; - preparing a plurality of secondary applications and an archive in which these applications are stored; each of said secondary applications being associated with a specific identifier from among the identifiers of said refrigeration apparatus and being configured to interact with said primary application so as to limit the functional parameters which can be set by means of said primary application to the functional parameters belonging to a specific subset of said subsets, said specific subset comprising the functional parameters for operating the refrigeration apparatus (101, 102, 103) identified by said specific identifier; said setting device comprising remote connection means designed to be connected to said archive, in order to download from it one of said secondary applications, and/or to said controller in order to set said functional parameters; said method further comprising: - an assignment step, during which an identifier which corresponds to the identifier of the refrigeration apparatus (101, 102, 103) in which said controller is integrated is recorded in said controller; - a detection step during which said setting device is connected to said controller in order to receive said identifier therefrom; - an adaptation step, comprising downloading from said archive the secondary application associated with said identifier received. - preparing a controller configured to operate a refrigeration apparatus (101, 102, 103) selected from among a plurality of refrigeration apparatuses belonging to a predefined group; a unique identifier being associated with each of said refrigeration apparatus; said controller having a set of settable functional parameters, said set comprising a plurality of subsets of functional parameters, each of said subsets being associated with one of said identifiers so as to be specifically designed for operation of the refrigeration apparatus (101, 102, 103) identified by said identifier; said controller being able to record one of said identifiers; - preparing a setting device provided with a primary application configured to set each of the functional parameters of said set and provided with a user interface via which said primary application may be operated; - preparing a plurality of secondary applications and an archive in which these applications are stored; each of said secondary applications being associated with a specific identifier from among the identifiers of said refrigeration apparatus and being configured to interact with said primary application so as to limit the functional parameters which can be set by means of said primary application to the functional parameters belonging to a specific subset of said subsets, said specific subset comprising the functional parameters for operating the refrigeration apparatus (101, 102, 103) identified by said specific identifier; - an assignment step, during which an identifier which corresponds to the identifier of the refrigeration apparatus (101, 102, 103) in which said controller is integrated is recorded in said controller; - a detection step during which said setting device is connected to said controller in order to receive said identifier therefrom; - an adaptation step, comprising downloading from said archive the secondary application associated with said identifier received.
