Answer:

General Temperature Setting Information

• In products with an electronic control panel, the refrigerator set to 38°F (3°C) and the freezer set to 0°F (-18°C) are ideal food storage temperatures.
• For products with a numbered dial control, refer to How to Set a Dial Control Refrigerator or Freezer.
• Storing food above 45°F is not safe.
• Always allow 24 hours for unit to reach new temperature setting.
• If the unit will not maintain set temperature, refer to Warm Refrigerator Troubleshooting, Warm Freezer Troubleshooting, or Sub-Zero Refrigerator or Freezer Too Cold for more information.
• For units running too cold, verify the proper temperature units (°F or °C) appear. Refer to Extremely Cold Temperature on Display for instructions to change the display temperature units (°F or °C).

• Classic (CL) and Designer (DET, DEC) products have a range of 34° - 42°F (1° - 6°C) in the refrigerator and -5° to 5°F (-20° to -15°C) in the freezer.
• Classic (BI) and Designer (IT, IC, ID) products have a range of 34° - 45°F (1° - 7°C) in the refrigerator and -5° to 5°F (-20° to -15°C) in the freezer.
• In units with an electronic control panel, the factory settings of 38°F (3°C) in a refrigerator and 0°F (-18°C) in a freezer are ideal food storage temperatures.
• Wine Storage products have different temperature ranges to preserve wine, see Wine Storage Temperature Ranges.
• The Designer Undercounter Beverage Center has different temperature ranges for a variety of beverages, see Designer Undercounter Beverage Center (DEU2450BG) Temperature Ranges.
• Setting the temperature higher or lower than factory settings causes the unit to run more or less, according to set temperature.
• It is not possible to set a temperature higher or lower than the range listed above.
• If the control panel does not respond, refer to Sub-Zero Electronic Control Panel Non-Responsive for troubleshooting steps.

1. Press the colder or warmer key for the desired refrigerator or freezer section.
   • Unit normally shows the actual temperature.
   • When the colder or warmer key is pressed, unit will show the set temperature.
2. After setting to desired temperature, display will return to actual temperature after 3 seconds.
3. The temperature change is not immediate. Allow 24 hours for the unit to reach the set temperature. An audible beep occurs during this operation.

1. To adjust the temperature, touch the temperature shown next to the corresponding zone icon.

1. Touch the temperature to adjust.
2. Touch + to increase or - to decrease the temperature until the desired temperature displays. The product saves the settings after the controls are not touched for 3 seconds.
