Before taking the unit into use you have to make sure that the unit has been
adjusted and that the unit, its filters and ductwork have been cleansed of
impurities arisen during building.
1. Start the ventilation unit and choose ventilation power at the control panel with
the fan operating switch. Before starting the unit make sure that there is no
condensation water in the unit.
General instructions for residential ventilation
In buildings with dwelling-specific ventilation the resident can influence ventilation
independently. Control takes place according to occupancy situation at the ventilation
power controller.
Absence operation (position 1)
When the dwelling is empty, ventilation can be set lower than normal operation
unless it causes damage to the structures.
Normal operation (position 2)
The ventilation system operates in accordance with the normal settings.
Boosted operation (position 3)
Cooking, taking a bath in the sauna or bathroom, drying clothes, use of toilet,
guests, overheat or similar situation may cause a need for higher than normal
ventilation. This is done by boosting ventilation in general or in certain rooms. As
an example, keep the flap of the cooker hood open during cooking; at other times,
keep it closed or in the minimum position. If there is an adjustable valve in the
ceiling of the sauna, keep it closed during a bath and at other times open.
Fireplace switch
The lower part of the operating panel also includes a separate fireplace switch,
which stops the extract fan of the unit. This creates momentary overpressure in the
dwelling, making it easier to light a fire. After the fireplace function has started, it
cannot be cancelled but the function stays active for 10 minutes. Only one operating
panel can be mounted for the unit.
WARNING!
If ventilation in the dwelling is closed, it also prevents new, clean outdoor air
from coming in and stale air from going out. Impurities originating from people,
structures and earth (such as carbon dioxide, humidity, odours, formaldehyde,
dust, radon etc.) quickly spoil room air, causing health hazards. Excessive
humidity may spoil the structures and cause mould and fungal growth. This is
why building regulations require that ventilation be kept in operation continuously
and that power be controlled in accordance with the user's needs.
2. The post-heating thermostat has been factory set at 15
20 °C. Set the thermostat
at the desired level when taking the unit into use. Post-heating fine adjustment can
be done by measuring temperature at the farthest supply valve during very cold
weather. Supply air temperature should not go below +15 °C. The controller is
located at the front panel.
3. In fault situations, the overheat protector of the post-heating resistor switches
off the heating resistor.
