SILENT CHZ
Models provided with an electronic humi-
distat which can be adjusted from 60% to
90 % RH (relative humidity) and with a ti-
mer, adjustable between 2 and 20 minutes.
Operation
Case 1: Automatic operation (fi g.9).
In automatic operation, the humidistat
causes the extractor to operate automa-
tically when the humidity level in the room
is higher than the set level. The extractor
will stop automatically when the humidity
drops below the selected level and after
the selected period set on the timer.
Case 2: Automatic operation as in case 1
with the facility to override the hygrostat
by means of the light switch (fi g.8), when
the humidity level in the room is lower
than the selected level. In this case, the
extractor continues to operate for the se-
lected period set on the timer after the
switch light has been switched off.
ATENTION: When the himidity rate is
above the selected value, the automatic
option takes precedence over the ma-
nual and the unit cannot then be swit-
ched off using a switch.
The desired humidity level is selected by
means of a potentiometer "% Hr" posi-
tioned on the printed circuit board (fi g.10)
and accessible once the grille (1) has
been removed.
− To reduce the humidity setting turn an-
ticlockwise (min.60 %).
− To increase the humidity setting turn
clockwise (max. 90 %).

To set the timer, turn the potentiome-
ter "t min." on the printed circuit board
(fi g.10):
− To reduce the "run on" time, turn anti-
clockwise (min. 2 minutes).
− To increase the "run on" time, turn
clockwise (max: 20 minutes).

SILENT-100 CHZ VISUAL (this version is
only available as SILENT-100)
These models are provided with an elec-
tronic humidistat which can be adjusted
between 60, 70, 80 or 90% RH (relative
humidity) and with an automatic run-
on-timer, adjustable between 5, 10 or 20
minutes. The humidistat adjustment can
be made using the corresponding adjust-
ment touch without the need to remove
the front grille of the fan.
Humidistat
The desired humidity level is selected by
means of an adjustment touch (5 fi g.11) lo-
cated on the front grill. The corresponding
relative humidity level, 60-70-80 or 90%, is
then visually indicated via one of four neon
lights. All models are factory set as stan-
dard to a 90% relative humidity level.
O ver-run timer
This product controls automatically the
over-run time, which is proportional to
the time that has been needed to bring
the relative humidity level to the adjusted
level, depending on which the over-run
will range from 2 minutes to a maximum
of 20 minutes.
