Operating and maintenance instructions for the ventilation unit
Some control panel functions are meant only
for installation or maintenance use. Because
these functions are not usually needed, they are
password-protected.
FOR INFORMATION
What is the ventilation unit used for?
The unit is meant to improve the indoor air quality, mainly
by ventilating.
The unit also recovers heat from the extract air. Some
models can be used for cooling supply air during summer.
The indoor humidity and carbon dioxide levels can be
controlled with the unit.
How does the ventilation unit work?
Functioning ventilation is the basis for living comfortably.
In mechanical ventilation, fresh air is blown into the
house, and used air is blown out. The purpose of
ventilation is to bring in clean, filtered air for people and
pets to breathe, and to extract impurities from indoor air.
A rotating heat exchanger recovers heat energy from
the extract air. The heat in the extract air warms up the
aluminium vanes in the heat exchanger, which in turn
releases the heat energy into the supply air when rotating,
with an efficiency of over 80%.
How is the ventilation unit used?
When ventilation is carefully designed and installed, you
do not have to do anything. Sit comfortably and enjoy the
fresh air.
How do I begin to use the unit?
The ventilation system should be installed and ready for
use.
Tap the control pane screen. Its keylock might be on.
Open the lock by pressing the lock button for a few
seconds.
The main page of the control panel should open:
The main page of the control panel
The circle around the operating mode button changes
its color depending on what the ventilation unit is doing.
The circle is green, when heat recovery is active. The circle
is orange and red when heating is active, and blue when
cooling is active.
If the text

displays on the screen instead,
the system has not been installed yet. In this case do
not continue using the panel. Contact the installing
technician instead.
If nothing happens when
you tap the screen, the
control panel battery may
have run out, or the
ventilation unit is
switched off. Switch on
the ventilation unit, or
charge the battery by
putting the panel in the
wall mount, or connect
a mobile charger (µUSB
connector).
