2.4.6. Filter warning
The controller of the ventilation unit uses a counter to
keep track of when the filters need to be cleaned or
replaced. If it detects that a filter is dirty, an LED (4) on
the ventilation unit starts blinking orange.

Caution!
If a dirty filter is detected, a signal is also sent to the
resident by suddenly reversing the operation of the
control: when the Low Speed button on the remote
device is pressed, the ventilation unit starts running at
high speed , and when the High Speed button is
pressed the ventilation unit starts running at low
speed . When this happens, check the LED on the
ventilation unit. If it is blinking orange, the filter needs
to be cleaned or replaced.

2.5. Grilles
The quantity of air that must be extracted is legally
regulated, and the quantity of air supplied must stand in
proportion to this. This means that the same amount of
air must be supplied as is extracted. The minimum air
quantity per room is also legally regulated. The quantities
have been selected to ensure that no unnecessary energy
is wasted whilst still achieving an optimal indoor climate.
This is why the air extraction and supply valves differ in
size between rooms. Each of the extraction and supply
grilles therefore has a specific fixed position and setting.
Note
It is very important that you do not adjust the grilles
in any way, to ensure proper operation of the entire
ventilation system. Grilles and air valves should not
be swapped around.
2.6. Applications with new housing
developments
High levels of moisture is found in building materials for
new housing – about 4,000 litres per house on average.
This moisture originates from wet building materials such
as concrete, cement, plaster and adhesives. Materials can
also become wet from rain during the construction
period. The best way to eliminate this moisture is to
