In this situation, looking at the heat-exchanger in ARDI would only show you the inlet temperature - the temperature coming from up-stream. There's two problems with this…
You can use references to solve the problem - in fact, the reference documentation specifically mentions this scenario.
Step by step, you need to….
This not only brings in both temperatures so you can see the performance of the heat-exchanger, but it also labels them appropriately so you can clearly see which is which.
