I am not sure if I understand your question.  The component only 
"operates" when the control signal is 1 and if the temperature of the 
fluid stream is above the setting temperature.

You will only get a constant temperature stream if the incoming 
temperature is above the setting point.

JFIX(Argument) converts the information in Argument to INTEGER(4).  You 
find it in many components, where the information that is passed to the 
component inside the arrays XIN and PAR are Real or Double Precision, 
and you want to pass that information to a local variable that is an 
Integer.
Please let me know if you still have questions about this component.

Best regards,

Diego
