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.
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.
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.
The desired humidity level is selected by
means of a potentiometer “ ” 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 “
” on the printed circuit board (fig.10):
- To reduce the "run on" time, turn
anticlockwise (min. 2 minutes)
- To increase the "run on" time , turn clockwise
(max: 20 minutes).
These models are provided with an electronic
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 adjustment touch without the
need to remove the front grille of the fan
The desired humidity level is selected by
means of an adjustment touch (5 fig.11)
located 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 standard
to a 90% relative humidity level.
