It has a memory for daily measurements of the highest and lowest temperature and humidity values, enabling you to analyze changes over time. The temperature and humidity trend indicator helps you monitor fluctuations at an hourly interval. The device includes a graphical weather forecast that presents pictograms for sunny, partly cloudy, overcast, rainy, and snowy weather.

Additionally, the ACC20 functions as a clock and calendar, offering a 12/24 hour format and the names of the days of the week in seven languages.
