the fan with timer utilising the same switch as
for the lighting circuit.
To set the timer, turn the potentiometer on the
printed circuit board as (fig. 7).
- To reduce the "run on" time, turn
anticlockwise (min. 1minutes)
- To increase the "run on" time , turn
clockwise (max: 30 minutes).
SILENT-300 CHZ
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 (fig.9)
In automatic operation, the humidistat
causes the extractor to operate automatically
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 (fig.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 himidity rate is
above the selected value, the automatic
option takes precedence over themanual
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 (fig.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 (fig.10):
- To reduce the "run on" time, turn
anticlockwise (min. 2minutes)
- 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.
