Room Extract

/h)
In case of 2
nd
Room Extract option (= 4
th
flap) this will allow
the user to deactivate the hourly switch of extract air from 2
nd
to1
st
room.
This makes sense in case your freeAir100 is installed inside
e.g. a closet.
Note
The deactivation is possible only when the 2
nd
Room Extract
is adjusted to 100 m³/h.
This feature is only available in devices with a serial number
of 3000 or higher.

Room Extract

/h)
The additional 2
nd
Room Extract module enables adjustment of max air flow of ventilation for
exhaust of the 2
nd
room. Diameter, length and number of turns in the ducting as well as air inlet
size limit the air stream (see table above):
• off: No exhaust ducting installed or extract opening blocked
• 30: One flex-duct connected (with extract valve
125)
• 60: Two flex-ducts installed (with extract valve
125 and completely open)
• 100: Three flex-ducts or spiral-seam pipe DN100 installed (with extract valve
200)
Note
Incorrect adjustment or high air friction coefficient will lead to higher noise level and premature
filter error warning.
