This is a single box, and you can only set the temperature of one zone in the big box. The small box is refrigerated temperature, and there is no refrigeration pipe. It needs to rely on the temperature of the big box for refrigeration (it will be affected by the ambient temperature and how much stuff is put in, it is recommended to set the freezer to a lower point). If the big box is refrigerated, the small box will not have a temperature.
