6.2 Using Test Button
The test button allows the individual blowers within the unit to be
checked for its operation. If the fan is running already, press the button
once to stop the fan, press again to switch on the standby fan, press
again to stop and so on. The fan will return to normal operation
after 30 seconds.
6.3 Setting Unit Airflow
6.3.1 Maximum Airflow
Ensure the power supply is switched off and that a link wire is
connected from the supply L to the SL terminal. Unplug all items
connected to the 'Net' connectors.
Switch on the power supply. Ensure unit cover is securely attached.
Wait for the fan to complete its self-test operation.
Remove the cover of the units external commissioning box. Measure
the airflow using standard commissioning instruments at a suitable
point in the ductwork. If adjustment is required, rotate the pot marked
'MAX' to obtain the desired airflow.
6.3.2 Minimum Trickle (Nominally 40%)
Repeat the same procedure as for maximum airflow above but without
the link wire between supply L and SL terminal. Ensure the trickle
switch is in the 'ON' position. The adjustment must be made on the pot
marked 'Min'.
The minimum setting (nominally 40%) must be below the maximum
setting, otherwise minimum setting will be automatically set to be the
same as the maximum.
After setting the airflows, re-connect all the items disconnected
previously. Ensure that the cover over the mains terminals is replaced
and that the cover of the controls enclosure is securely fastened.
