DANGER
Respect all references regarding safety and use of the freeAir 100 in part General [G]!
Display- and Operating Elements
on Main Switch
Use for turning the freeAir 100 on or off.
All LEDs will blink slow during start and self-test operation.
During a controlled „Shut Down“ LEDs will blink fast. Vent flaps
are being shut.
Warning
Wait to restart until all LEDs are off.
- Button
Operation of your freeAir 100 is so simple –you only need this
button as the only control element.
With this button you can control Comfort Level, start or stop the
Turbo, select Sleep or Dehumidification mode (see below).
You can change the Comfort Level by pushing - Button
several times fast. The more blue LEDs are lit the more active
the instrument controls (minimum ventilation, CO2, humidity,
cooling...).
Changing Comfort Level may not immediately change fan speed.

[ O ]
Audible Signals
A continuous beep-sound indicates occurrence of excessive
temperatures or harmful CO2-Concentrations.
(See part [S] Service).
Yellow LED
This LED will blink slowly during Turbo operation.
The LED will blink fast during Turbo Cool operation.
Continuous illumination indicates:
•reduced minimum ventilation due to active defrost function
eliminating room air humidification, or
•the freeAir pauses,
because outside air is so humid that room air condensation
could occur or
because outside temperatures are below -22°C (-30°F).
Blue LEDs
The number of illuminated blue LEDs indicates the selected
Comfort Level.
These LEDs will blink slowly during Sleep mode.
These LEDs will flash during Dehumidification mode.
Note
Blue LEDs will go dark after 3 minutes so as not to disturb you.
Push the - Button to “wake” them up.

[ O ]
Red LED
A fast blinking red LED indicates that the last filter change has
been more than 8,700 hours ago (~ 1 year).
A slow blinking red LED indicates that the air stream through a
dirty and partially clogged filter is impaired. A slow blinking red
LED can also indicate air stream obstructions such as
inappropriately dimensioned openings between spaces of supply
and extract air.
Continuous illumination indicates control error. (See appendix
[S] Service).
DANGER
•An overly dirty filter (indicated by the red LED) can reduce supply and extract air flow. This
in turn can lead to diminished air quality and over or under pressure in connected rooms.
•Neglecting of filter change indicator may result in growth of harmful microbes.
Note
Excessive dust, inside or outside of the building during the building phase, may require
a premature filter change.
The red LED will appear continuously if the WiFi of the freeAir has been activated using the
freeAir Connect USB but is not connected to the local WiFi router.
This may be due to the wrong WiFi name or password, too far from the router or a problem with
the router or the internet.
The WiFi function is available up from pcb version 9 (software version 2.02 and higher).

Comfort Operation
After switching it on the freeAir 100 will operate in Comfort mode.
In this mode the device will operate automatically:
If installed correctly the device will supply all connected living areas
with the right amount of fresh air. Minimum air flow, CO2 content,
relative and absolute humidity inside and out are all taken into
account.
Push the - Button several times to select Comfort Level 1 (one
LED). This is the quietest level and should be selected if you like a
quiet setting for instance for bed rooms.
Level 3 (3 LEDs are lit) is the normal setting for living rooms.
Turbo Operation
Push the - Button until you hear 4 short beeps. This model
should be selected if you wish to air out rooms at the highest
device setting for 30 minutes. Comfort operation will be restored
automatically after 30 minutes. Comfort Level can also be restored
via the - Button.
Sleep Mode
Push and hold the - Button until you hear 4 short beeps followed
by a very long beep. Your freeAir100 will pause for 90 minutes
before switching back to Comfort mode.

Turbo Cool Operation
The cooling function of your freeAir 100 is completely self-acting.
First, at high outside temperatures the heat exchanger operates as a cold exchanger, so the
summer heat stays outside, if you keep the windows and doors closed as in winter.
When sufficient average summer temperatures are reached, after one day your freeAir 100 is
switching into summer operation automatically. The device uses the fresh night air for cooling
by opening the bypass flap, thereby increasing the airflow.
Start Turbo Cool operation (and hereby switching into the summer operation) by pushing and
holding the - Button till you hear 4 short beeps followed by a long beep followed again by 4
short beeps. This will open the bypass flap and switch the device to its highest power setting for
3 hours. In this setting your living space can be cooled down noticeably by fresh evening and
night air after a hot day.
Turbo Cool operation is switched off automatically when outside air temperature is too hot.
Dehumidification Operation
Push and hold the - Button for 15 seconds to activate this mode. This operation can be used
in case of an application where the usual dehumidification level provided by the Comfort mode
is not sufficient (for instance in a basement room). The freeAir100 will beep three times and
blue LEDs will flash. Dehumidification will work at humidity levels as low as 45 % relative
humidity.
Dehumidification is optimally controlled through constant measuring of absolute humidity both
inside and outside effectively suppressing humidity import through outside air. Thereby the
ventilation is increasing to assure evacuation of humidity, as soon as absolute humidity inside
the building is higher than outside.

Notes
•The freeAir 100 compensates for air stream resistance, due to connected conduit or dirty
filter, by increasing fan speed.
•Therefore supply and exhaust air stream remain constant and balanced.
•“Dirty Filter” error will be indicated once maximum fan speed is reached.
•Longer supply ducting will result in a change in balance between the air flow of the 1st and
2nd room in favor of the 1st room (normal 1 : 1).
2. Open the appropriate passage and attach the appropriate
ductings or connectors by taking care to use an O-ring or
sealant.
Note
In case of the bare brickwork set with BOX, just remove
the plugs,
for the bare brickwork set without BOX the openings have
to be cut.
3. Use the included adapter, if you wish to connect another
Round-Flex 75 mm to the 2nd room exhaust adapter.
Note
For the bare brickwork set with BOX, this adapter must be
separated.
In case of the bare brickwork set without BOX,
a fourth Round-Flex-Duct can be added using a Flat-Flex-
Round-Flex-Adapter.
