System description
Operation
Fan speed
The fan speed has to be adjusted to the need
for ventilation. See “consequences of incorrect
operation”.
Min Must not be used in the first year
of operation or when the home is
in use
Normal Normal operation
Max Used for raised humidity levels, e.g.
when the bathroom is in use, and
generally when there is an
increased need for ventilation
If a lot of moisture is generated, it is important to
use Max for a while afterwards to give the system
time to extract the moisture from the room.
CI60
The fan speed is adjusted
using the + and – buttons on
the panel.
CI600
The fan speed is selected using the
arrow keys and confirmed with OK.
Consequences of incorrect operation
Condensation
A lot of moisture is often generated in wet rooms as a result of drying clothes, showering,
etc. If the outdoor air is cold, it will cool the walls down and the moisture in the indoor air
could condense on the unit. If you experience this, you must increase ventilation to
Max when a lot of moisture is being generated. Increased ventilation will ensure that
the humid air is extracted from the room and replaced with drier air.
Filters
Old and blocked filters provide poor ventilation and can also cause condensation
problems.
New homes
New homes give off large quantities of moisture and gases from textiles, building materials,
paint, etc. This is known as
off-gassing and can cause discolouration of walls and surfaces
in the home. Ventilation is therefore very important!
The unit provides ventilation in the home.
It supplies
fresh air to living rooms and bedrooms via valves, which are
normally located in the ceiling. At the same time
used air is extracted
from the kitchen, bathroom, toilet and laundry room.
The unit contains a rotating heat exchanger that recovers
around 80% of the heat in the extract air and transfers it to the
supply air when needed.
The unit is operated from a separate control panel.
