3.2 Cooker hood function
The cooker hood function balances the air flows when the
cooker hood is used. This will help to prevent house nega-
tive pressure and improves fume extraction capability. The
ventilation boost level during the function can be defined.
The function starts automatically when the damper in a
Swegon CASA cooker hood is opened or when a cooker
hood defined IO is active.
The function and the air flows can be commisioned
from the menu

cooker hood air flows are in balance. Compensation
increases supply air flow. (If roof fan compensation is
selected, the extract air flow is first reduced).
Boost state Compensation.
Fine tune Boost mode
compensation value if necessary.
Hood boost
adjusts the ventilation level during the func-
tion, for example, to achieve sufficient discharge velocity
or odour extraction.

when using a cooker hood which is
connected to the roof fan. Compensation is achieved by
slowing the extract air fan.
