[TRNSYS-users] Problem of Type16

Dear all.
 
I am using Type16c, because I'd like to calculate some tilted surface radiations from a series of total horizontal radiation data given by Type9. But the calculated south beam radiation seems to be strange. It has a peak in the very early morning and almost no radiation around noon or in the afternoon. I think the diffuse radiation is OK since it's like a sine-curve. Is this a bug? I used to often use Type16 in the early versions before 17, and don't remenber such a problem.
I've attached the file and a weather data. If anyone give any information, it would be realy help. Thanks in advance.
 
Kind regards,
Mika
