Hi all, please help. I'm inserting an exhaust fan.

Error:
   ** Severe  ** ValidateExhaustFanInput: The number of AirflowNetwork:MultiZone:Component:ZoneExhaustFan is not equal to the number of Fan:ZoneExhaust fans defined in ZoneHVAC:EquipmentConnections
   **   ~~~   ** The number of AirflowNetwork:MultiZone:Component:ZoneExhaustFan is 2
   **   ~~~   ** The number of Zone exhaust fans defined in ZoneHVAC:EquipmentConnections is 5
   ** Severe  ** AirflowNetwork:MultiZone:Component:ZoneExhaustFan  = 118204 XFAN1 WC is defined and never used.
   ** Severe  ** AirflowNetwork:MultiZone:Component:ZoneExhaustFan  = 118204 XFAN2 WC is defined and never used.
