Setting the Temperature - 52 Litre
The digital thermostat fitted to the
National Luna Portable refrigerator
allows accurate setting of the desired
cooling temperatures.
With the single compartment refrigerators,
temperatures can be selected between
+20°C and -30°C in 1°C increments.
When powering up the fridge, the temperature inside the fridge will be reflected on the display.
(NOTE: the previously set temperature will be in memory)
To select the new cooling temperature, press and hold the button until the display starts to flash.
(The previous set temperature will be displayed).
Press or to raise or lower the desired temperature. The thermostat will accept the new
setting and exit the setting mode 10 seconds after the last button was pressed. (It will now remember
the new set temperature).
The temperature display will reflect the inner bin temperature prior to the new setting. Provided the
new setting is colder, the compressor will then switch on and cool the fridge further to the set point.
(During this time the run indicator light will be displayed).
The user must take into account that the unit has thinner insulation than the classic range.
At very high ambient temperatures it is not recommended to set the freezer to below -11°C (as the
compressor will automatically speed up to the high power mode in order to attain colder temperatures
and thereby use excessive battery power).
