Important
You must not change the settings
when cleaning the supply air dif-
fuser and extract air diffuser. The
air diffusers have be adjusted in
conjunction with commissioning
of the ventilation system.
A qualified technician sets the fan
speeds in accordance with na-
tional regulations in conjunction
with the commissioning of the
ventilation system. You should
not change the air flow yourself
as this may disruption system
functionality.
