OPTIMUM TEMPERATURE IN VACUUM COMPARTMENT
The Vacuum  Compartment  with  optimum  temperature  setting  of  approximately  –1ºC/+1ºC  can  be  automatically  adjusted  to  achieve  ultimate  freshness.  Once  CO2  is  present  in  the Vacuum  
Compartment, the temperature will be adjusted automatically to maintain the best condition for nutrients to be preserved*5....

Food can stay fresh longer when it is stored at its ideal temperature. With Photocatalyst Preservation and Optimum Temperature settings in the Vacuum Compartment, food items can be stored 
longer without losing its original freshness and nutrient level.
