Hi! I am getting the following warning message while modelling AirflowNetwork in EnergyPlus:

 ** Severe  ** The number of entered AirflowNetwork:Distribution:Component:Fan objects is 1
   ** Severe  ** The number of entered AirLoopHVAC objects is 0
   **   ~~~   ** Both numbers should be equal. Please check your inputs.
   **  Fatal  ** GetAirflowNetworkInput: Errors found getting inputs. Previous error(s) cause program termination.
   ...Summary of Errors that led to program termination:
   ..... Reference severe error count=2
   ..... Last severe error=The number of entered AirLoopHVAC objects is 0

I am modelling a HVAC loop with only a supply fan on the supply side and an ideal load on the demand side. The fan is modelled as a constant volume fan and connected to the airloop of the HVAC, so i don't understand when the error says that the number of AirLoopHVAC objects is 0.

Could you please help me? Here is the link

Thank you
