The fan can be controlled by 0–10 VDC analog control
or by digital control. You can choose two limit values for
the fan control. The Low value specifies the minimum
fan control percentage and the High value specifies
the maximum fan control percentage. If analog control

equals 0 VDC and the maximum fan control percentage

fan control percentage = Ext L is active and the
maximum fan control percentage = Ext H is active. See
