SILENT-100 CHZ DESIGN
Models provided with an electronic
humidistat 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 auto-
matically 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
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
anticlockwise (min. 2 minutes)
- To increase the "run on" time, turn
clockwise (max: 20 minutes).
Maintenance
The extractor fan only requires periodical
cleaning using a cloth lightly impregnated
with a soft detergent.
