This is standard feature of KK range. This is an additional option available for ST/CHL/IL ranges.
Order number: * PLUS (option factory preinstalled).
Defrosting in this case is programmable (the User sets periodicity and duration). This function is carried out while the unit is working. This advanced technology holds the temperature stable, allowing only a minor increase in the chamber (considerably higher temperature rise is caused by opening the door).
Standard defrost function (heating the chamber to 20-30°C at the time selected by the user) is not available on CHL series devices equipped with PLUS function.
