Initial adjustment
The ventilation system works properly when air flows in the rooms have been measured and
adjusted with the valves in accordance with the planned values.
After the initial adjustment, the
position of the ventilation valves must not be changed . If there is an outlet valve with a knob in the
ceiling of the sauna, it can be adjusted as needed. The initial adjustment ensures that a
sufficient amount of air is circulated and that extract air flow is always greater than supply
air flow, i.e. the dwelling is negatively pressured compared to outdoor air. If the dwelling
is positively pressured, air in the dwelling penetrates the outer envelope of the building and
between windows, which may cause humidity damage during the heating season.
In normal conditions basic ventilation with change of air every two hours is sufficient in living
areas. Boosting is needed during for example sauna baths, cooking, clothes washing or
family parties.
If the user does not know the measured air flows, the adjacent table shows approximate
extract air flows as well as the total electricity consumption of the fans at various fan speeds.
The table also shows the fan speed that is sufficient for recommended basic ventilation in
dwellings of different sizes.
The switch positions, i.e. fan speeds, displayed in the table on a darker background are
factory preset values. If needed, an expert or electrician can change (or has changed during
the initial adjustment) settings and select speeds shown on a white background instead.
Voltage changes are also made by an expert, not the user himself.
