If the temperature is very high, setting it to 1 is more appropriate and the most energy-saving.

If the indoor temperature is moderate, or there is air conditioning to cool down, just adjust it to 2-3.

The digital file of the thermostat of this mechanical refrigerator does not show the specific temperature, because it is greatly affected by the change of environmental temperature. Users should adjust the size of digital gear according to the seasonal ambient temperature. Take the seven-speed thermostat as an example: turn it down in summer (1-3), turn it up in winter (4-6), and turn it to mid-range in spring and autumn (3-4). This can ensure that the temperature in the refrigerator is within the normal range, that is, the freezing room is about MINUS 18 degrees, and the refrigerating room is between 4-8 degrees. This is not only conducive to the frozen preservation of food, but also relatively energy-saving, which can avoid various failures and effectively extend the service life of the refrigerator.

If you have special requirements, you can put it in the refrigerator and actually measure it with a thermometer. If the temperature is too high, raise the gear. If the temperature is low, just lower it to make the temperature in the refrigerator reach the temperature range you need.

If you want to quickly freeze food, you can temporarily adjust it to the highest gear (7th gear), but it can't exceed 4 hours. Otherwise, it will cause the compressor to work overtime for a long time, which will not only consume a lot of electricity, but also damage the compressor and shorten its service life.
