SETUP
VENTILATION MODES
Four ventilation unit modes
At home
Use this mode when the dwelling or the premises are occupied.
Away
Use this mode when the dwelling or premises are unoccupied,
e.g. during a trip or other long absence.
Fireplace mode
Use this mode when, for example, you are making a fire in the
fireplace. The mode is primarily used to create momentary
overpressure in the dwelling.
Boost
Use this mode to increase the ventilation rate, e.g. when there
are more people than usual in the dwelling or elsewhere on the
premises.
TIP
Using the At home,
Away, and Boost modes
according to need
saves energy.
IMPORTANT
Prolonged overpressure
can result in damage
to the structures of the
building.
4. Use the
Plus
and
Minus
buttons to set the extract air fan
ratio as a percentage of the maximum output ratio. The
fan speed (rpm) will change accordingly. Measure and
adjust the extract air flows from the valves.
5. Select
OK
. Supply and extract air flow settings are now
complete.
6. Record the set percentages in the measurement log.
Do not change the output ratio between the supply and
extract air fans once the settings are complete. The
same ratio is also used in the Away and Boost modes.
TIP
You can browse the
Basic fan settings
by using the
Right
arrow
button.
NOTE
If the use of the ventilation unit has been started before
airflow adjustment, the airflow must be measured through
the air volume adjustment menu (see “Save and restore
settings”). This ensures that the unit settings are optimal for
the adjustment of the airflows.
