Dear Sasuda-san,

Nice to hear you. Thanks for your comment.
Yes, I selected "string" as unit and, additionally, optimised the order of
the components.
I attached very simple sample that creates error #125.

>TRNSYS Message    125 : The referenced Unit has a bad parameter value.
>Reported information  : Parameter # 2, Reported Problem: The pipe length
must be greater than 0.

Best regards,
Mika
