[TRNSYS-users] Abouth Typ557

[Jeff Thornton]

Cathy,

We are in the process of re-writing 557 to be able to be used more than 
once in a simulation.  In the meantime, we do have a second version of 
type 557 recoded with a different name and number that allows you to use 
two of them in a simulation.  They will not interact thermally but it 
does allow you to have two separate borefields.  Let me know if you are 
interested.

Jeff
