If you put automatic
the ventilation is boosted with the set value
during the sauna. This function prevents any
disruptive variations in the fan speeds while
the sauna is working.
SUMMER MODE
Summer mode bypasses the ventilation unit's
heat exchanger when it needs to cool and the
outdoor air is colder than the room air. You
then get cool outdoor air in the room. The
ventilation automatically boosts so that the
best possible cooling is obtained.
The heat exchanger takes care of the cool
indoor air during hot summer days. The
capacity in summer mode can be selected
from a quick menu, and the ventilation unit
will then automatically determine the cooling.

The capacity in summer mode can be modi-
fied by editing the required setting.
When necessary summer mode also boosts the

tion can be selected. The boost function can
be limited with the weekly program "Silent",
when automatic boost is not permitted.

You can set the gain values for heating and
cooling from the settings menu. The function
boosts the ventilation according to the differ-
ence between the room temperature and set-
ting value, so that a deviation of one degree
results in boosting as set for the gain value.
Boosting is limited if the supply air is too hot
or too cold.
You can select whether the function should be
active in the Away mode from the menu.
SHUT OFF
The ventilation unit can be shut off by select-
ing "Shut off" from the "Smart Functions"
