Calibration
For the system to work correctly, it needs to be configured� This helps ensure the quietest possible and most energy-efficient oper-
ation� See under the Tools heading at www�duco�eu for information about determining ventilation flow rates�
The adjustment procedure depends on whether iAV is operated as master (stand alone) or as slave (external control)�
06.A
Calibration with iAV as slave (EXTERNAL CONTROL)
Follow the adjustment procedure described in the manual of the master unit�
06.B
Calibration with iAV as master (STAND ALONE)
Follow the steps described in this chapter to install components� The adjustment is done in two phases: setting exhaust vents and
actual adjustment�
Setting exhaust vents
The exhaust vents are installed in an exhaust duct for moisture-laden/stale air extraction� In order to calibrate the air extraction
correctly, these vents must be set depending on the situation in accordance with the table below� The possible situations can be
found on the following page� When using DucoVent Design exhaust vents always leave the outer ring in place for an acoustic effect�
