[TRNSYS-users] Type60c

[David BRADLEY]

Farah,
   with Type60, you have to specify three of the four flow rates. In 
your case, you need to connect the collector loop pump outlet flow rate 
to both tank inlet 2 and tank outlet 2. You correctly connected the load 
flow to tank inlet 1. If that is what you've done and the results don't 
make sense, please send the input file.

   Incidentally, in your case of matched flows and no heat exchanger, 
there isn't any real need to use Type60; Type4 is a bit more intuitive 
and may suit your needs.
Best,
  David
