Then close the cover firmly.
Which configuration mode should I choose?
Button
Air calibration using 'HIGH'
This method is standard and has the
lowest consumption� Recommended
in the majority of homes�
Air calibration using 'LOW'
This method offers a boost mode
but may give rise to more noise
and higher consumption�
Low mode (10%)
Low mode (14-33%)*
Medium mode (50%)
High mode (100%)
High mode (100%)
Boost mode (143-333%)*
The percentages in the table indicate what percentage of the flow rate configured will be extracted�
The configuration mode chosen does not affect the operation of the AUTO mode�
* In the ‘LOW’ configuration, the percentage in low mode and boost mode is dependent on the type of
home (see section "06�D Setting type of home" on page 11) and limited to the maximum achievable
ventilation system flow rate�
HIGH

Now measure the other vents� The flow rate from these other vents must only be
adjusted at the vents themselves.

Repeat steps
6
and
7
until the desired flow rate has been obtained at each vent�

Exit configuration mode� This can be done in two ways:
• Long-press ‘AUTO’ on a paired User controller or CO
