Re: [TRNSYS-users] From PhD-student

Dear Julio:

Thanks for pointing out this problem.  I found that the generic model of 
the DEGS was calculating the waste heat for one unit, but it was not 
multiplying this value by the number of units.   I have fixed this 
problem and this new version will be available in the next TRNSYS release.
Thank you very much.

Diego
