3.1 Air flows

Particular airflows should be found from house ventilation 
plan. The units air flow curves are found in the section 
“Technical data”. A qualified person should adjust the ven-
tilation air flows with the help of measurement equipment 
so that they correspond with the ventilation plan.

Air flows for all basic operating modes must be set 
so that the ventilation unit works correctly! 

Enter 

the settings in the commissioning report.

Before you start to adjust the air flows, ensure that the 
filters are clean and that there are no foreign objects or 
debris inside the ventilation unit.

consumption. Travelling mode can be used when the 
home is empty for long periods. 

Adjust

 the supply fan control (%) for the Travelling 

mode. The extract air flow is defined automatically 
based on the basic air flows. 

3.1.3 Maximum automatic boost

Automatic boost level can be limited if it’s disturbing.

Adjust

 the supply fan control (%) for the max Smart 

boost. The extract air flow is defined automatically 
based on the basic air flows.

3.1.4 General notifications

In new homes, there is still construction moisture and the 
higher ventilation level is needed to remove the moisture. 

If there is a sauna, pool or other moisture producer in 
the home, It is recommended to boost ventilation on 
demand. This can be managed with Smart humidity 
control or active use the ventilation unit’s boost mode.

Before commissioning, all tasks in Installation section must be completed. Before the ventilation system can be taken in 
use, the basic supply and extract air flows must be adjusted. If cooker hood is used, the cooker hood function boost air 
flow and balancing should be adjusted. If the automatic Home/Away/Boost Smart function is used it must be commis-
sioned, see section 4.

Important

The system should be commissioned by a 
qualified person. The air flows must not be 
changed by the user, because it could dis-
rupt the ventilation system operation.

Air flows must be adjusted according to the 
local regulations. 

Never adjust the air flows under the units 
specified minimum.
