The steps set out below match the numbers shown in the preceding
illustration.
1
Press ‘HIGH’ or ‘LOW’ on the IQ-unit to activate the configuration
mode for 30 minutes.
2
With zonally controlled exhaust only: select the zone with the
highest pressure drop (usually the zone located furthest from the
central extract unit).
3
Measure the exhaust vent with the highest pressure drop (usually
the vent with the highest flow rate).
4
Adjust the fan speed of the central extract unit until the desired
flow rate through the exhaust vent in step
3
has been attained.
This can be done using the arrow keys on the IQ-unit if it has
been connected to it (via PWM or WTW). If the zone is fitted with
a constant volume control, the point must be found at which the
fan runs as slow as possible while attaining the desired flow rate.
If the fan speed cannot be adjusted, the desired flow rate can be
attained by fine-tuning the feed-through component (e.g. using the
arrow keys on the iAV control valve)

. Note that this can gener-
ate more noise and higher energy consumption!

Measure any remaining vents within the current zone and fine-
tune them using the exhaust vent. Work from highest to lowest
flow rate.
