How to adjust the temperature of Meiling three-door refrigerator BCD-22 1CHC?

Mechanical temperature control and temperature adjustment should be adjusted according to the season. The higher the number of gears, the lower the temperature. The zero gear is the stop gear and the highest gear is the forced cooling gear. Take the seventh gear as an example: the colder the weather (winter), the greater the adjustment range (5.6), and the hotter the weather (summer), the smaller the adjustment range (2.3). Generally, the middle tune (3.4) is better in spring and autumn. If the ambient temperature is low in winter, it is best to turn on the winter temperature compensation switch at the same time, but don't forget to turn off this switch when the temperature gets warmer, otherwise it will consume a lot of electricity.

It is my pleasure to serve you. Thank you for your trust and support for Meiling products!
