3.2.2 Automatic Home/Away/Boost system

The function is available only on models equipped with
a carbon dioxide sensor. The automatic control system
controls the ventilation airflow variably according to the
carbon dioxide level in the home.
This function should always be set in conjunction with
commissioning.

The settings menu shows the value "A
rent level of carbon dioxide. The function is set by defin-
ing the limits values Home and Away. A suitable Home
limit value can be determined by reading the "A
value from the menu when a normal number of people
are in the home. Similarly, you can determine the Away
limit value by reading the "A+ now" value when the
property has been empty for several hours.

3.2.3 Automatic humidity system

The function is available only on models equipped with
a humidity sensor. The function boosts the ventilation
according to the normal moisture load caused by a
person, for example, when a shower adds extra moistu-
re to the residence. If the relative humidity of residence
rises above 60% over a longer period, the set airflows
must be increased, and the reason for the high level of
moisture investigated.

Sauna boost
The value "RH now", the current moisture level, is
shown on the settings menu.
The automatic humidity system measures the daily
average value in the extract air and compares this with
the current value. The ventilation starts to be boosted
variably when the humidity has risen as much as the
Boost limit value.
When the sauna is working, the ventilation is boosted
with the set value, through the activation of the auto-
matic sauna limitation. This function prevents variations
in the fan speeds while the sauna is working.
3.2.4 Automatic air quality control
The function is available only on models equipped with
automatic air quality. Automatic air quality boosts the
ventilation variably according to the indoor air quality.
This function should always be set in conjunction with
commissioning.
Auto Air Quality control

Filter time
The settings menu shows the value "AQ now" the
current air quality level. The function is set by specifying
the boost limits where you want the ventilation boost
to start and the value at which you want the ventilation
unit to reach maximum boost. Appropriate values can
be established based on the "AQ now" value shown in
the menu.
If it seems that the ventilation system reacts too quickly
to changes in the air quality level, you can increase the
filtering time.
3.2.5 Cooker hood function
The cooker hood function balances the ventilation when
the cooker fan is used to help prevent excessive nega-
tive pressure and improves fume extraction capability
of the cooker hood. The function starts automatically
when the damper in a compatible cooker hood is
opened and runs until the damper is closed.
