The Set CFM Total In a Room command is used to set the airflow values for all of the diffusers in a room. The recommended airflow values are based upon the heating and cooling loads specified in the room.
To set the total airflow in a room, go to
Ribbon: DM HVAC->Diffusers-> 
Set CFM Total In a Room
Pulldown Menu: DM HVAC->Set CFM Total->In a Room
You will be prompted to select the room in which to set the total airflow.
Specify point inside room:
The Set CFM Total in a Room dialog box will appear.
Set CFM Total in a Room Dialog Box
Room: The name of the selected room.
Type: The room type of the selected room.
See the CFM Setting Adjustment Methods section for more information about the Average CFM in Diffusers and Prorate CFM in Diffusers settings.
Supply Air
Room Minimum CFM: The Minimum Supply Air for room specified in the room itself or the schedule. See the Rooms section for more information.
Cooling CFM: The airflow required to cool the room based upon the cooling load. See the Cooling, Supply CFM value in the Print Supply Air Requirements section for more information.
Heating CFM: The airflow required to heat the room based upon the heating load. See the Heating, Supply CFM value in the Print Supply Air Requirements section for more information.
Required CFM: The airflow required in the room. This value is the largest of the Room Minimum CFM, Cooling CFM, and Heating CFM values.
Current CFM: The current supply airflow in the room. This value is based upon the CFM values of the supply diffusers in the room on the drawing.
New CFM: The new supply airflow to be set in the room. This value will be distributed among the supply diffusers based upon whether Average CFM in Diffusers or Prorate CFM in Diffusers is selected.
Return / Exhaust Air
Current Return CFM: The current return airflow in the room. This value is based upon the CFM values of the return diffusers in the room on the drawing.
New Return CFM: The new return airflow to be set in the room. This value will be distributed among the return diffusers based upon whether Average CFM in Diffusers or Prorate CFM in Diffusers is selected.
Current Exhaust CFM: The current exhaust airflow in the room. This value is based upon the CFM values of the exhaust diffusers in the room on the drawing.
New Exhaust CFM: The new exhaust airflow to be set in the room. This value will be distributed among the exhaust diffusers based upon whether Average CFM in Diffusers or Prorate CFM in Diffusers is selected.
Setting the Total Airflow in a Room
When the values in the dialog box are set correctly, press the OK button. The new CFM values will be set in the diffusers in the room.
