During all modes of operation, the main control board will cycle the dampers, fan, and heater as
necessary to maintain the desired temperature. Typical operation is as follows:
Select Temp
This feature maintains optimum temperatures for specific items.
The CITRUS setting will maintain a drawer temperature of 43 °F by circulating warmed air or cooled
air as needed. The dampers will close and the heater will turn on if warmed air is required to maintain
43 °F. The dampers will open if cooled air is required.
The PRODUCE setting will maintain a drawer temperature of 34 °F by circulating warmed air or cooled
air as needed. The dampers will close and the heater will turn on if warmed air is required to maintain
34 °F. The dampers will open if cooled air is required.
The MEAT setting will maintain a drawer temperature of 32 °F by circulating warmed air or cooled
air as needed. The dampers will close and the heater will turn on if warmed air is required to maintain
32 °F. The dampers will open if cooled air is required.
The Climate Control drawer display will show the selected temperature for approximately 4 seconds
after a Select Temp mode has been selected. After approximately 4 seconds, the actual temperature of
the drawer will be displayed. Refer to the Temperature Table for drawer temperatures.
Express Chill
This feature cools items by opening the dampers and circulating air from the freezer compartment
throughout the drawer. The fan will be on at all times during Express Chill.
The Climate Control Drawer display will show the number of minutes (or minutes remaining) for the
Express Chill mode selected on the control panel. The display will not show the temperature of the
