EnergyPlus DOAS Water Cooling Coil Sizing Error
I'm having an issue with EnergyPlus 9.6. I added 2 DOAS units to my model, but my model fails to complete the sizing of the cooling coil of the second DOAS unit. The sequence of my setup for the DOAS is (OA - heating coil - cooling coil - fan).
For some reason the [Coil inlet air temperature used for sizing = -997.59 [C]], and I tried everything I can to fix it.
I tried to change (Design Inlet/Outlet Air Temperature) from (autosize) to fixed temperatures, but for some reason I still see the same error.
Here is the full list of errors I'm seeing:

Update: To clarify, this is my second DOAS unit in this model, which is identical to my first DOAS unit, but I'm only getting this error after adding the second one.
