Hello, The two parts are independent and can be tempered from 5°C to 20°C. In the application, it is possible to select different "Programs" (Reds, Whites, Sparkling Wines, Whisky, Full-bodied, Dessert, Champagne and Rosé) which will set a certain temperature for the selected area. It is still possible to set the temperature manually for each of the zones, either in the app or directly on the cellar at the top using the touch buttons.
