Hi, third topic in the last few days ... but at this point my project is nearly finished and my understanding of modelica is getting better and better.

i got as far as simulating but one boolean variable doesnt behave as it should and i cant find the error.

unfortunatly the attatchments in this forum seem to be broken so i cant provide you a immage of the Plot.

What i can say that the Booliean condition is B = A<18 ; and a is >18 nearly all the time but B gets true on the first time A gets smaller than 18 and stays true besides A getting bigger than 18 again. can someone explain why this behavoir can happen and how to fix it?
replacing the condition with a small if condition doesnt help at all.
