I can't seem to understand why I am still getting a node connection error for a connected inlet and outlet node. I am working on a custom HVAC design. The CHW Supply inlet and outlet node is an adiabatic pipe. attached is the idf and err file. I couldn't find a solution searching the web. Thanks in advance.
