Method of controlling operation of an appliance

A method of operating a refrigerator comprising a storage cavity, a user interface, an electrically-operated cooling system, and electronic control system, the method comprising:

• receiving, at the user interface, a setting selection comprising at least a control parameter and/or an operating program to be implemented by the refrigerator;
• operating the electronic control system to control the electrically-operated cooling system to cool down the storage cavity, based on the setting selection;
• estimating, by the electronic control system, a resource consumption of at least the electrically-operated cooling system when it operates based on the setting selection;
• determining, by the electronic control system, a degree of ecological impact caused by the electrically-operated cooling system based on the estimated resource consumption;
• and
• indicating the determined degree of ecological impact at the user interface.

A method of controlling operation of an appliance, comprising:

• presenting at a user interface, an option to change an operating program of the appliance;
• operating the appliance according to a selected change of the operating program;
• displaying, on the user interface, an indicator representing the change in the operating program;
• and
• displaying, on the user interface, separately from the displayed indicator representing the change in the operating program, a degree of ecological impact caused by the selected change of the operating program, wherein the degree of ecological impact indicates a level of resource consumption used by the appliance to operate according to the selected operating program.

A method of controlling operation of an appliance, comprising:

• presenting at a user interface, an option to change an operating program of the appliance, wherein the option to change the operating program comprises an option to change an operation of an electrically-operated cooling system from a first program to a second program or an option to change a duration of a washing program from a first duration to a second duration;
• operating the appliance according to a selected change of the operating program;
• displaying, on the user interface, an indicator representing the change in the operating program;
• and
• displaying, on the user interface, separately from the displayed indicator representing the change in the operating program, a degree of ecological impact caused by the selected change of the operating program, wherein the degree of ecological impact indicates a level of resource consumption used by the appliance to operate according to the selected operating program.
