[TRNSYS-users] Dynamic efficiency

[David BRADLEY]

Seyyed,

   I would recommend that you work your way through the 
01-GettingStarted.pdf manual that is located in the \Documentation 
directory. There is also a 02-SimulationStudio.pdf manual that will 
explain how the interface functions and how to interpret the information 
that is being presented in each of the fields.

   The mathematical descriptions of the components (such as the boiler) 
are not provided with the demo version.

regards,

  David
