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
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).
Models provided with a PIR (passive
infra-red)
detector. The
unit
starts
automatically
when
a
movement
is
detected with a maximum distance of 4
metres (fig.9).
They are also fitted with an adjustable
"run on" timer (1 to 30 minutes), and the
unit will continue to operate for the set
period after initiation by the movement
detector.
To set the temporisation, turn the
potentiometer on the printed board (fig.7):
- To reduce the "run on" time,
turn
anticlockwise (min. 1 minute)
- To increase the "run on" time,
turn
clockwise (max: 30 minutes).
ATTENTION: The product also includes
an over-run timer facility that starts the
fan after the first 50 seconds of non-
operation. After these first 50 seconds the
fan operates automatically.
