Thanks for the e-mail.  There is indeed a typo in the 696 source code.  It turns out that the 5th output (flow rate) is missing and all the other outputs beyond that are shifted up by one.  If you'd like, I can send you the new source code.  Please let me know.  Otherwise simply replace:

200   OUT(1)=T_OUT
OUT(2)=W_OUT
OUT(3)=RH_OUT*100.
OUT(4)=P_OUT
OUT(5)=QS_H
OUT(6)=QL_H
OUT(7)=QT_C
OUT(8)=QS_C
OUT(9)=QL_C
OUT(10)=Q_REHEAT

with

200   OUT(1)=T_OUT
OUT(2)=W_OUT
OUT(3)=RH_OUT*100.
OUT(4)=FLOW
OUT(5)=P_OUT
OUT(6)=QS_H
OUT(7)=QL_H
OUT(8)=QT_C
OUT(9)=QS_C
OUT(10)=QL_C
OUT(11)=Q_REHEAT

Our sincerest apologies.

Jeff
