The climate class determines the temperature range within which the refrigerator operates efficiently and can properly preserve food. Climate classes include, SN (Subnormal): 10°C - 32°C, N (Normal): 16°C - 32°C, ST (Subtropical): 16°C - 38°C and T (Tropical): 16 °C - 43°C.

Freshness zones are special compartments in the refrigerator that maintain a constant temperature and humidity, ideal for keeping fresh food such as fruit, vegetables, meat and fish.
