Hello,<br>I'm using a Type60c tank in a simple direct solar water heating model. I get the "negative flow" error. The input/outputs are defined as:<br>inlet 1 flow: mains flow outlet 1 flow: -2<br>
inlet 2 flow: solar pump flow outlet 2 flow: solar pump flow<br>Not sure where else to look. Any thoughts?<br>Thanks,<br>Brian<br clear="all"><br>-- <br>Brian Raichle<br>Department of Technology and Environmental Design<br>
