[TRNSYS-users] Urgent!! - help on Type 340 Multiport Storage

[thiemann.stefan at vdi.de]

Hello everybody,

currently I have a problem with Type 340. I use it on system with
 different heat sources. Heat exchanger 1 is a solar loop, Heat
 exchanger 2 is warm water supply. 2 Doubleports are used for heating
 purpose.
Unfortuanately the system is very unstable. Sometimes it works,
 sometimes it hangs up without any warning or message.
Has anybody made the same experience?
Any suggestions?

I am sure that I defined every parameter right. So the problem depends
 on the simulation system...

Thanks, 

S. Thiemann
