Hello, I am trying to simulate on openstudio a simple water loop with one cooling tower and a water heating coil to understand the makeup water usage, link to download the osm file. I have already followed the instructions on similar problems, however it has not worked. The error says "missing required property,'air outlet node name'. I have imported the example file CoolingTower:SingleSpeed:MultiCell as starting point and then added the HVAC loop.

Can anyone please help?
