PRO 48 Use & Care 6 Electronic Control System The electronic control system of the PRO 48 monitors and accurately displays compartment temperatures within one degree of your pre-set temperatures. It also monitors the operation of the unit and lets you know if there is a problem. The interior control panel located at the top of the refrigerator door compartment has key pads to set temperatures and control functions of the electronic control system. Refer to the illustration below. TEMPERATURE CONTROL Your new PRO 48 was thoroughly inspected and tested before it was shipped from the Sub-Zero factory. Temperatures are preset at 38°F (3°C) in refrigerator compartments and 0°F (-18°C) in the freezer compartments. There are three sets of WARMER and COLDER key pads on the interior control panel, two for the refrigerator compartments (upper door and lower drawers) and one for the freezer compartments. To adjust the temperature in any of the three compartments, press the WARMER or COLDER key pad for that compartment. Digital temperatures for each of the three compartments are displayed in the exterior temperature display. Temperature ranges are -5°F (-20°C) to +5°F° (-15°C°) in the freezer sections and 34°F (1°C) to 45°F (7°C) in the refrigerator sections. It is normal for temperatures to fluctuate slightly, depending on external influences such as an open door, the degree of humidity and room temperature. IMPORTANT NOTE: Always allow 24 hours for compartments to reach the temperature you set. EXTERIOR TEMPERATURE DISPLAYS Electronic control system functions, such as digital temperatures and service indicators, are displayed in two exterior temperature displays located on the grille. The display in the lower left area of the grille shows the temperature and indicators for freezer compartments, and the display in the lower right gives readouts for refrigerator compartments. Refer to the illustrations below. TEMPERATURE DISPLAY The electronic control system can display temperatures in Fahrenheit (°F) or Celsius (°C). To convert Fahrenheit to Celsius, turn the unit off then back on. Within the first minute after turning the unit on, press and hold the ALARM key pad and the POWER key pad simultaneously for five seconds, then release. A 'C' will appear in each of the exterior temperature displays. Follow the same procedure to convert from Celsius to Fahrenheit. Exterior temperature displays.
