20Operation FunctionWhen the system power is initally engaged, the default set temperature are -2℉ for the freezer and 38℉ forthe set refrigerator, respectively. The numbers shown on the digital display panel stand for the actualcompartments temperatures. When the compartment temperatures go down, so do the numbers on thedisplay panel, and finally they reach the set temperatures. Once the system is stabilized, the displaytemperatures are the set temperature.1) Freezer Temperature Control.To select a set temperature, press the Freezer Temp. button. The display shows the set temperature from-14℉ to 8 ℉ in sequence.2) Refrigerator Temperature Control.To select a set temperature, press the Refrigerator Temp. button. The display shown the set temperaturefrom 34℉ to 46℉ in sequence.note) Because of the temperature sensor sensivity, the refrigerator can be under and/or over cooled whenthe air flow is blocked by stored foods. (Temperature range of the sensor : 15℉∼80℉)In the event of a power failure, if the freezer temperature is maintained lower than 41℉, the lastselected set temperature and functions memorized in EEPROM will be restored when the power is on.● Select the Power Freeze or Power Cool buttons separately.● These buttons are toggled ON and OFF and the indicators as well.● Although you select Power Freeze or Power Cool, the set temperatures in the freezer and refrigerator are not changed.● The set temperatures for the compartments can be changed while these functions are in use.1) Power Freeze function1-1) When you press the Power Freeze button, the LED indicator lights right away, but there is 10 seconds lag time to anactual operation. When this button is pressed again, the Power Freeze function stops and the indicator is off immediately .1-2) If you select Power Freeze, both the compressor and the freezer fan run for 2 ½ hours continuously.1-3) During Power Freeze, the freezer retains the current settings.1-4) When Power Freeze expires, the indicator goes off and the freezer set temperature will be restored.2) Power Cool function2-1) Power Cool operation and the indicator work exactly same as the Power Freeze function.2-2) When Power Cool is selected, COMP and R-FAN operate continuosly until the refrigerator reaches 25℉. This function willbe terminated after 2 ½ hr running.9-3) Power Freeze Function and Power Cool Functions.9-1) Digital Panel9-2) Temperature Control Function
