Hi all,
I'm working to implement an ERV who's exhaust inlet node equals an zone exhaust fan's outlet node. I'm modeling a kitchen space and hope to use this configuration to get properly model heating energy savings.
In terms of the E+ model, I am able to directly modify the node (this E+ file runs successfully!):

That said, OS handles these node references differently. It looks like instead of a node name, the OS HeatExchanger object references a node's outlet port (also equal to a connection's handle).

Anyone know how best to make an equivalent change in OS? Whenever I try to manually change the OS object to reference the appropriate node's outlet ports I get errors.
