The unit is expected to function properly. An exact comparison is not possible for lack of reference. The device also has a serious fault: For operation with the power supply an internal temperature of nearly 30 ° C is always displayed, even with the windows open and the actual internal temperature of almost 5 ° C. Disappointed I was also the Company Service: I did not even get an answer to a question. Strange is also the Wettervorhesage Icon: Most of the time shows it rain, even if currently and in the next 5 hours, the sun will shine.
