If the unit is connected to a pipework system with lines that
are more than five metres long or smooth lines that are more
than ten metres long, the fan level must be adapted to en-
sure that the pressure losses that are caused by the air net-
work are offset. This change in level is implemented using
the unit's electronics box.
