Checking the temperature in the coldest zone
Thanks to the temperature indicator, you can check regularly that the
temperature of the coldest zone is correct. Indeed, the temperature
inside the refrigerator is a function of several factors such as the
ambient temperature of the room, the amount of food stored, the
frequency of opening the door. Take these factors into consideration
when setting the device.
When the indicator reads "OK", it means that your thermostat is set
correctly, and that the indoor temperature is correct.
If the color of the indicator is white, it means that the temperature is
too high, it is necessary in this case to increase the setting of the
thermostat and to wait 12 hours to carry out a new
visual control of the indicator.
After loading or opening the door, the indicator may turn white after
a few moments.
