[TRNSYS-users] Likely bugs in Type655 and Type666

[knut.erik.enerstvedt at niva.no]

Hello,

You are absolutely right about this. There is a mismatch between 
documentation and example datafile on one side and source code on the 
other. The first column in the datafile should consist of COP ratios, 
while the second column should consist of capacity ratios. There have been 
some postings about this on the list in the past.

Best regards,
Knut Erik Enerstvedt

Am I
