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



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

Hello,
I am doing a simulation with a Type 19 zone, solar collectors, PV, hot water tank... When I run the simulation with a time step of 9 minutes or more, the program runs fine. As soon as I use a time step of 8 minutes or less, I get a range check error.
After adding and removing all the different components, I have found that the culprit is the Type 19 window model. I am using the windows that have Transmittance Calculated Internally (19Wind-1).  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.

I have attached the model with only the zone related components.
Has anyone managed to use the Temperature Level Type 19 zone with time steps below 9 minutes with these windows?

Thanks,

Rémi
