1. General
The most important function of the ventilation
system is to ensure clean and fresh indoor air
and to remove moisture. The air in the home
should be changed at a continuous and suf-
ficient rate to ensure a pleasant indoor climate
and avoid damage to building elements caused
by dampness. The ventilation unit should be
stopped only while service work is in progress.
Note. Read Important information chapter
carefully before any use of the unit.
Compatibility

Additional automatic systems available as accessory packs!
All Smart automation systems are easy to set up for use. The sensors are situated in-
side the device, so installing them does not require any special cabling in a residence,
and they are also easy to install later, in already-mounted Smart ventilation units.

Smart ventilation system is able to recognise residents’ needs. The Smart automatic systems check the
quality of the indoor air, and thus know exactly how much ventilation is needed in a given situation.
Automatic Home/Away/Boost system
(RH + CO₂)
automatically calculates the ventilation
settings for the “Away” status, and thus
saves energy when there is nobody at
home. When the residents are home, it
automatically adds just the right amount
of fresh air to the residence. Ventilation is
regulated evenly and according to need,
without any intrusive accelerations from
one operating state to another.
Also included: humidity automation.
Automatic air quality system
(RH + VOC)
boosts the ventilation level if any impuri-
ties are detected in the indoor air, such as
various harmful odours or fumes (volatile
organic compounds).
Also included: humidity automation.
