This seems to be a basic question, did you go through the tutorials? Because when you complete LabVIEW basic 1 you should be good to do all these things by yourself.

 

To answer your question: You must be Comparison operator and also a loop.

The Elapsed Time express VI is perfect for this situation.  Make the timer reset when you are less than the temperature and watch the output go high when the timer expires.
