What is the temperature range for operating the Cold Boost or Chill Boost function?

The Cold Boost function (Convertible model) turns off automatically after 3 hours if the temperature drops below -13°F (-25°C), or after 24 hours if the temperature stays above -13°F (-25°C). The Chill Boost function on the Refrigerator model is used to quickly chill food and can be turned on or off by pressing the Chill Boost button. Both functions are designed to quickly bring food to the desired temperature. (Page 8)
