[TRNSYS-users] Type 56 , active Layers

[David Bradley]

John,
 I have run into this error myself but have never been able to track 
down the reason for it. I have always solved it reducing the minimum 
flow that I am requesting Type56 to accept (which may cause it to 
autosegment).
Kind regards,
 David
