Hi Rike, hi to all type 340 users,

I am also working with type340 and I also have a problem with the double 
ports. As soon as the flow rate (which is connected to the first double 
port) in my input file changes from 0 to some positive value, i get an 
error. In the beginning it was some balance error, now TRNSYS complains 
about a mass flow which must not be negative. Of course the printer 
shows a positive mass flow before it leads to the store...

Maybe our errors are caused by an old Proforma version. The most recent 
type340.dll version is 1.99F (dll-file date 11.03.05). I have that 
version. It offers more than 120 parameters, four heat exchangers, 10 
double ports... 
www.transsolar.com/__software/download/en/ts_type_340_en.pdf whereas my 
proforma version only shows me up to 5 double ports and 3 heat 
exchangers . Actually the model doesnt seem to run at all when i switch 
one of them off via Parameter 6 which allows to set the number of heat 
exchangers... Also there are less heat exchanger options (stratified 
charging) and there is no parameter 126 (ver) allowing to change to the 
fitting mode.

Does maybe anybody have some more recent proforma type340.tpf?
My version is dated Friday, 26. November 2004, 14:06:08.

Thank you, greetz to everybody!
