VENTILATION PROFILES
THE VENTILATION UNIT HAS FOUR VENTILATION PROFILES:
AT HOME
Use this ventilation
profile when the
dwelling or the
premises are
occupied
AWAY
Use this ventilation profile
when the dwelling or
premises are unoccupied,
e.g. during a trip or other
long absence.
FIREPLACE PROFILE
Use this ventilation profile when, for example,
you are making a fire in the fireplace. This
profile is primarily used to create momentary
overpressure in the dwelling to help elevate
back spillage into the room.
BOOST
Use this profile to increase
the ventilation rate, e.g. when
there are more people than
usual in the dwelling or local
ventilation regulations dictate.
SYMBOLS FOR VENTILATION PROFILES
The following symbols are used on the main displays of the profiles:

of air is normal.
•
Droplet and two shaded bars — The relative humidity of air is slightly higher than normal.
Ventilation efficiency needs to be boosted. When the automatic fan speed on the relative
humidity of the air is turned on, ventilation is boosted control based automatically.
•
Droplet and three shaded bars — The relative humidity of air is significantly higher than
normal. The fan speed will be automatically increased if automatic adjustment has been chosen.
