SPECIAL FEATURES

SUPER COOLING FEATURE (QUICK COOLING)
When this function is selected, the LED2 light turns on, which indicates that a signal is being sent to the board. When
the shut-off temperature indicated by the thermistor and the potentiometer is reached, the board does not send the shut-
off signal to the compressor, which continues operating non-stop for an hour. The LED light will turn off when the
compressor stops operating. The following diagram shows the additional operating time and how the temperature
decreases.
TEMPERATURE RECORD IN THE EVAPORATOR
VACATION MODE FEATURE
When this function is selected, the LED1 light turns on, which indicates that a signal is being sent to the board. The
defrost cycle will start according to the stored time in the board memory. The following defrost cycles will start after
48 hours of accumulated operating compressor time. This feature is cleared by the board's integrated photocell when
the fresh food compartment door is opened.
OPERATION TEST
Select the Vacation Mode feature, which will turn on the LED1 light. Close the hole located in the upper front part of
the air tower, on the fresh food compartment ceiling, to the right of the screw that holds the air tower. Wait a while and
then open the hole again, which will turn off the LED1 light, indicating that the feature is not operating anymore.
When the electronic board sends the signal to activate the operating cycle of the compressor, the potentiometer and
temperature sensor begin working to maintain food at the desired temperature. When the potentiometer knob is turned,
it indicates to the sensor the temperature range within which the fresh food compartment is to be kept. Based on this
range, the sensor then sends a signal to indicate the operation and rest periods of the compressor.
