Chun Kwong,
  You have to use the correct mode of Type89 (Type89d in this case). In 
TRNSYS 16, the start time is the hour of the year at the start of the 
simulation (0 to start at the very beginning of the year, 1 if you want 
to start on January 1 at 1AM, 744 if you want to start on February 1 at 
midnight). In TRNSYS 15 it was a bit different. If you are using TRNSYS 
15, let me know and I will explain in more detail.
Regards,
 David
