measured over the iris damper, that is constant air volume

Carbon dioxide, humidity, and
temperature boost of blowers
The blower power of the ventilation unit is controlled
based on load conditions and on the measurements
collected by the humidity and/or carbon dioxide sensors.
The concentration of carbon dioxide and/or humidity
is kept below the limit value set in the control panel.
Humidity control manages the blowers based on the
internal and possible external humidity transmitters in
the ventilation unit. The standard ventilation unit delivery
contains one inbuilt humidity sensor. Three carbon
dioxide transmitters and three humidity transmitters can
be connected to a ventilation unit. Transmitters are extras.
Carbon dioxide, humidity and temperature boost can
activate in At home mode. Humidity booster can activate
in Away mode as well.
If humidity booster is not enough to remove humidity
from the rooms, the boosted humidity removal can be
activated from the settings menu (Settings > Booster >
Humidity Booster > Boosted humidity removal). When
humidity booster is active, the boosted humidity removal
operates automatically if the outdoor temperature is
less than 0°C and the function has been activated in the
Settings menu. This function slows down the rotation
of the heat exchangers, which allows for more efficient
humidity removal.
Supply air humidity removal is available for certain
ventilation units. The absolute humidity of supply air
remains on a level configured in Settings > System
configuration > Drying settings.
Overtime (Office usage mode)
In the Office mode the ventilation unit shuts down unless
a time program instructs it to operate, or the overtime
setting is active.
Overtime length is configured in the control panel. It can
be activated from the control panel or from a separate
button (extra). Overtime control can be interrupted from
the control panel. Overtime can also be activated via
Modbus.
Overpressure function should be used only
temporarily for making lighting the fireplace easier.
The fireplace combustion air must be provided by
other means than via the ventilation unit.
NOTE
Manual boost
Boost and ventilation functions are started from the
control panel. Boost raises the speed of both blowers for
the time wanted (default setting is 30 minutes). Boosting
can be interrupted from the control panel.
Cooking hood and central vacuum
cleaner modes
Switching to cooking hood or central vacuum cleaner
mode is possible only by external control (potential-free
contact). The intent is to maintain the pressure level of the
apartment, despite using the cooking hood and/or the
central vacuum cleaner.
Summer night cooling
On summer nights, the room temperatures can be
lowered with cool night air. Heat recovery and heating are
turned off during summer night cooling. Blower speeds
are controlled by the selected control mode. Summer
night cooling starts and stops automatically when it has
been activated from the panel.
Overpressure (fireplace function)
Controlling overpressure can be started from the control
panel or from a separate button (extra), which will make
lighting a fireplace easier. Overpressure time and the
supply and exhaust blower speeds can be set from the
control panel. Overpressure control can be interrupted
from the control panel. Over pressure control lowers the
speed of the exhaust air blower and raises the supply air
blower speed for 10 minutes.
