Comfort-Level
Press the - Button repeatedly to change the Comfort Level.
More blue LEDs indicate a more active operation (minimum
ventilation, humidity, CO2, cooling ... etc.). However, a change
in Comfort Level does not have to lead to the immediate increase
in fan speed.
Blinking blue LEDs indicate Service Operation.

minutes (Turbo mode), push the - Button until you hear 4 short
beeps.
The unit performs a software reset when you press the
- Button for 15 more seconds until the LEDs turn off. This is
e.g. required for software updates.

Intended use
The freeAir plus is an intelligent active transfer unit that ventilates rooms in apartments or
houses. The device is installed in an inside wall.
Stale air is drawn from the Preferred Room that is connected via the freeAir plus. Fresh air from
the Outdoor Air Room (e.g. the corridor) streams in the Preferred Room (e.g. the sleeping room)
through the gap under the door or through another appropriate passive vent. If the measured air
quality in the Outdoor Air Room is lower than in the Preferred Room, the ventilation is reduced.
Inappropriate use
The device is exclusively to be used for ventilation purposes.
DANGER
Only air not containing flammable, explosive or corrosive components or air not containing any
other dangerous or hazardous components may be used for ventilating purposes.
Disposal
Dispose the freeAir plus in accordance with your local rules, regulations or guide lines.
Please pay special attention to correctly sorted separation of metal, plastics and electronics.

Comfort-Operation
The freeAir plus will operate in Comfort-Mode after it is turned on.
The device will automatically operate as expected: The connected
Preferred Room will be supplied with as much fresh air as possible
(based on intended use of the device, correct installation and available
fresh air in the Outdoor Air Room, fresh air is drawn from).
The freeAir plus will take minimal ventilation, VOC content, relative and
absolute humidity, temperature and potential cooling into account.
Use the –Button to select Comfort-Level 1 (one blue LED is lit), if you
are sensitive to noise in the bedroom. Comfort-Level 3 is considered
standard operation.
Turbo-Operation
If you wish to ventilate for 30 minutes at the highest power level, press and hold the –Button
until you hear 4 short beeps.
Normal Comfort-Operation will resume afterward. Maximum power ventilation can be
interrupted by pressing the –Button.
Reset
Press and hold the –Button for 20 seconds until all LDS are off.
The freeAir plus will respond with a software reset, (also required for a software update), and
return to normal Comfort-Level operation.
Note
The freeAir plus includes a VOC-sensor that measures the concentration of volatile organic
compounds, thereby comparing air quality in both connected spaces. To simplify, VOC data is
converted to CO2 values.
