[EnergyPlus_Support] question about node connection

["zhaicq98" <chaoqinz@xxxxxxxxxxxxxx>]

In my system, the outside air first goes through an air to air heat 
exchanger where it changes sensible and latent heat with the building 
relief air as well as a solid desiccant wheel before it enters into 
the outside air mixer. I know this system is very similar to the 
example file DesiccantCVRh.idf and acturally I created my input file 
according to this example. The difference is that except the 
regeneration fan there is a fan drawing the process air through the 
heat exchanger and desiccant wheel and another fan drawing the 
building relief air through the heat exchanger. 

My question is in which branches or objects I should put these two 
fans. First, I did not add them to any objects, and then I got the 
warning messages that said "node connection error, air node not on 
any branch or parent object". Then add them in the AIR LOOP EQUIPMENT 
LIST, together with the air to air heat exchanger and solid desiccant 
wheel, as well as the outside air mixer. The warning messages remain 
the same. 

Can anyone tell me where I should add this two fans?

Thanks,
Chaoqin
