Hello people, yesterday I had the problem that with my 407 year of construction 5/2008 100KW did not turn at 30 degrees outside temperature of the motor fan anymore. The climate did not go accordingly. I then looked around something whether I find something somewhere or see at once when it got a little cooler (23 degrees outside temperature) the fan ran again. Now a question, someone knows some problem what to do with such a symptom. and possibly has a schematic from the air control? Greetings Chris
