you need to convert expression like "arbTimer >=resetDuration + RESET_WAIT" to boolean equivalent like "cond_input = (arbTimer >=resetDuration + RESET_WAIT) "

and use cond_input in stateflow diagramm. I advise you to replace complex condition with simple one, and later in code you can insert how to calculate it .
