The temperature inside the appliance is too cold/warm. What are the correct temperature settings?

The optimum normal air temperatures in the centre of cabinets should be as follows; Refrigerator +3.5°C Chiller 0°C Freezer *** -18°C Freezer * -6°C Freezer ** -12°C Freezer **** -24°C (Using Fast Freeze switch, not at normal running temperature.)
