humidity) and with a timer, adjustable
between 1 and 30 minutes.
The selection of desired humidity le-
vel is done with the dip-switches 4
and 5: setting between 60, 70, 80 and
90 %RH:
The selection of the run on time is
done with the dip-switches 6 and 7: se-

CONTINUOUS OPERATION
1. Automatic operation (fi g.3): the
extractor is connected to the main
supply with only two wires. The
extractor operates continuously at
the setting trickle speed. When the
humidity level in the room is higher
than the set level the fan is boosted
to high speed. When the humidity
drops below the selected level and
after the selected period set on the
timer the fan automatically returns
to trickle.
2. Automatic operation with the faci-
lity to override the humidity sen-
sor and make the extractor run
in boost by means of an external
switch (fi g.4a) or the light switch
(fi g.4b), when the humidity level in
the room is lower than the selec-
ted level. In this case, the extrac-
tor operates in high speed for the
selected period set on the timer
after the light switch has been
switched off, and then goes back in
low speed unless the humidity level
exceeds the set point.
ATTENTION: When the humidity rate
is above the selected value, the auto-
matic option takes precedence over
the manual.
SPECIFIC RECOMMENDATIONS:
• If the humidity is always above 90%
RH, the fan will always run at full
speed.
• If the humidity in the room is always
less than 60%, the fan will only ope-
rate at trickle speed when running
in automatic operation.
If the fan never runs at boost:
• The setting of the humidity sensor
is at maximum. Change the setting
• The level of humidity in the room is
below 60% RH
If the fan always runs at boost
• The setting of the humidity sensor
is at minimum. Change the setting
• The level of humidity in the room is
above 90% RH
