Important information!
Airflows
The air in the home should be changed at a
continuous and sufficient rate to ensure a pleas-
ant indoor climate and avoid damage to building
elements caused by dampness� The ventilation
unit should be stopped only while service work
is in progress�
The airflow from the ventilation unit can be
controlled to generate the various airflows from
a Premium control panel or a Premium cooker
hood�
• Away
= a low airflow, which can be utilized
when no one is in the home and there is no
need for the same ventilation that is normally
in use, e�g� for moisture-removal�
• Home = normal airflow�
• Boost = a high airflow, used in connection
with cooking, taking a sauna bath, showering,
drying laundry and similar activities�
The Away/Home operating modes and the tem-
perature of the supply air can be controlled with
the ventilation unit’s built-in weekly timer; how-
ever the operating mode can always be changed
from the Premium control panel or the Premium
cooker hood�
A low airflow when the home is unoccupied
means economical operation� This saves on fan
energy and the home heating system does not
have to heat as much air during the cold season�
The most important function of the venti-
lation system is to ensure that the indoor
air will be continuously fresh and to re-
move impurities and moisture from the air.
You should therefore make an appraisal of
whether a low airflow is sufficient while the
home is unoccupied. The low airflow mode
must absolutely not be used when someone
is in the home.
If the load on the home is greater than
you’ve anticipated, then you should increase
the normal airflow to a correspondingly
higher rate.
Drying laundry
A tumbler dryer of extract air type or a drying
cabinet must not be connected to the system
due to the high moisture content in the air leav-
ing them� We recommend a condensing tumbler
dryer without duct connection�
Freeze protection
During periods of cold weather, the heat ex-
changer is liable to freeze if the extract air is
humid� A protective function then automatically
reduces the speed of the supply air fan� Under
such conditions, variations in the fan speed are
therefore normal�
Filters
The ventilation unit must not be operated with-
out filters� Use only filters recommended by
Swegon in the ventilation unit�
Commissioning
The ventilation should not be commissioned until
all work that produces large quantities of grind-
ing dust or other impurities has been completed�
