Re: [TRNSYS-users] Pump Type749 question

Sergio,
 When you see a parameter that refers to a logical unit number, it is always an indication that the component requires an external data file. The location of the data file is specified in the "external files" tab of the proforma. I would recommend that you refer to the Type749 documentation located in the ..\Trnsys17\Tess Models\Documentation\07-HydronicsLibraryMathematicalReference.pdf to answer your questions about the Type.
Regards,

Hello TRNSYS users:

I have a question about Type749's parameter "Logical unit for pump data file". What is it? what is its function?. My problem is that the system curve does not intersect with pump curve. Can be for this parameter? or where can be the mistake?. How do i determinate what is the correct logical number for my system?.

I wait your answer and I hope that someone can guide me in this topic. Thank you very much.

Regards.
