SAG 0-3 V
ComfoAir XL keeps the air volume constant. Output
can be programmed in three air volume stages via a
display. The SAG 0-3 CV switch can then be used to
select the stages high, medium and low.
The housing is white (RAL 9010) and ideal for
installation in a fitted housing with a depth of 40 mm.
A surface-mounted housing is available for mounting.
CO
2/s
sensor
ComfoAir XL can also be controlled using a CO
2
sensor. A CO
2
sensor measures the CO
2
concentration in the ambient air at the position to
which it is attached. The CO
2
sensor selects the air
vent stage on the basis of the ventilation requirement
in the room. If the CO
2
concentration is high, the
ventilation stage is increased automatically. If the
CO
2
concentration is low, the ventilation stage is
reduced automatically.
Diaphragm siphon
A diaphragm siphon does not have a gooseneck;
instead it comprises a non-return valve made of
silicone rubber, which opens as soon as water
presses against the membrane and closes again due
to the vacuum in the unit. The siphon can be
equipped on request with a heating cable to protect
against frost or the formation of ice.
Siphon heater
Siphons are sensitive to frost. Siphon heating
reduces the risk of frost damage.
Joining piece
All units are delivered with rectangular connections
and tubtaras. They can be used to connect a drain
from rectangular to round.
