Model provided with a 4 positions adjust-
able electronic timer: Fig.5 shows how to
connect the fan with timer utilising the

SILENT CHZ DESIGN
Models provided with an electronic humidi-
stat which can be adjusted from 60% to 90
% RH (relative humidity) and with a timer,
adjustable between 2 and 20 minutes.
Operation
Case 1: Automatic operation (fi g.9)
In automatic operation, the humidistat
causes the extractor to operate automati-
cally 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 extrac-
tor continues to operate for the selected
period set on the timer after the switch
light has been switched off.
ATENTION: When the humidity rate is
above the selected value, the automa-
tic option takes precedence over the
manual and the unit cannot then be
switched off using a switch.
The desired humidity level is selected
by means of a potentiometer "% Hr"
positioned on the printed circuit board
(fi g.10) and accessible once the grille (1)
has been removed.
- To increase the humidity setting turn
anticlockwise (min.60 %)
- To reduce the humidity setting turn
clockwise (max. 90 %)
To set the timer, turn the potentiometer
"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).
