[TRNSYS-users] Range Check Error using Small time steps with Type 19

[Diego A. Arias]

Dear Rémi,

I think I found the reason for your error.  Type19 sizes a storage array 
that contains 1000 spots.  They are not enough when you select a time 
step smaller than 8 minutes.  You can modify the size of the storage 
array in Type19 to a larger number.
I am going to add an error message to guide users if someone encounters 
this limitation in the future.
Best regards,

Diego

If I remove these windows from the model and change the Zone model and Geometry inputs to reflect a zone with no windows, the range check error disapears.
