Unsure about autosizing results
If I use only one coil in the system and I would like it to be autosize. Am I doing it right there I am not very sure.

But Design Load is 76kW already but my coil only has 46kW
One more question is that in the Sizing:System I dont have any precool or preheat in the outdoor airduct what should I input there
