 Set the fan output to 44% in the controller menu.
Note
If the air duct is longer or there are more bends, perform
the following individual system calculation.
Individual system calculation
 Calculate the system pressure drop as the sum of all compo-
nents installed in the air duct.
 Enter the calculated pressure drop on the X-axis of the dia-
gram. Read off the fan output from the Y-axis and adjust the
fan output parameter in the appliance menu.
