Display- and Operating Elements
on Main Switch
Use for turning the freeAir on or off.
All LEDs will blink slow during start and self-test operation.
Firmware version is indicated by individual non-illuminating
LEDs (digitally starting from the bottom).
During a controlled „Shut Down“ LEDs will blink fast. Vent flaps
are being shut.
- Button
Operation of your freeAir100 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.

Operation

[ 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.
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,
- because outside temperatures are below -22°C (-30°F).
this LED will blink fast during Turbo Cool operation.
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.

Red LED
A fast blinking red LED indicates that the last filter change has
been more than 8,000 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.
•Diminished oxygen levels can pose a health risk.
•A dirty filter can also grow germs.
USB Port
The USB port on the left side of the device serves as
a connection to the (free to our customers) freeAir-
Connect software and respective updates.
Note
Please visit our website at www.bluMartin.de for
updates under Service / Downloads.

Louver
The louver in the left part of the air output side can be rotated to
accommodate any desired blow direction.
DANGER
Do not insert any foreign objects into the supply opening.
Notes
•Due to the optional 2nd room air supply connection - air is only supplied from the left part of
the air discharge.
•In case the included supply air outlet for wide through results in drafty condition alternative
supply air outlet hardware is available.

Comfort Operation
After switching it on the freeAir100 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
Start Turbo Cool operation by pushing and holding the - Button till you hear 4 short beeps
followed by a long beeps 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.

for 2nd room connection:
•Connecting ducting, conduits and valves must have
low air stream resistance.
•For 2nd room connection the below stated decrease
in pressure must not be exceeded.
•The supply air conduits must not exceed
the below noted length.

Notes
•The freeAir 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. Cut out the appropriate passage and attach the
appropriate ducting or connector taking care to use an O-
ring or sealant.
3. Use the included adapter if you wish to connect the 3x
Round-Flex 75 mm to the 2nd Room Exhaust port.

Installation Side
DANGER
•The freeAir100 must not be installed in immediate vicinity of flammable material or
harmful chemicals.
•During planing consider all relevant local building, safety and fire codes. Especially in
situations where indoor air is used for combustion (wood stove, fire place...etc.).
Select installation location that allows condensing moisture to
flow off freely while preventing any danger through the formation
of icicles and/or icy spots on the ground.
Notes
•The condensate may be drained through a hose with the extra Condensate drain outside
article FA00.2005 (outside between wall and insulation or inside).
•The formation of ice can be reduced with the software option de-icing (only with the
permission of the owner of the building).
