Temperature Settings in a D283/183
The settings must be no more than 5 degrees different, i.e., 6 & 11 or 7 & 12, or 8 & 13. 4 degrees is preferred at factory setting 8/12. If the difference is too great the unit will run too cold and this may not be reflected in the display. In addition you may see a humidity alarm when the humidity is in fact fine.
Use the roof of the chiller box for storage as a last resort. i.e., Utilise the shelves above, first. If using the roof of the chiller box, ensure bottles are not touching the back wall.
