7 End Vent Suction Setting Procedure.
The use of an inverter on the B80, B160, B300
fan system allows the end vent suction to be
adjusted by varying the fan speed.
The description for adjusting the fan speed is
given in the following section. Apart from this
change the commissioning section in the
manual should be followed.
End vent suction (B80, B160, B300 )
For these systems the end vent suction is
adjusted by altering the low speed setting of
the inverter within the local relay unit.
1. Check that the fan damper is fully open
and secure.
2. Ensure the SmartCom³ is in a programmed
ON time.
3. Set the required room temperature above
the actual room temperature.
4. After a 30s delay the fan should run.
5. The fan should now be running and the
