OPERATION
Case 1: Automatic operation (fi g.3). In
automatic operation, the extract fan
operates continuously on the trickle
setting speed. When the humidity lev-
el in the room is higher than the set
level the fan will boost to high speed.
When the humidity drops below the
selected level and after the selected
period set on the timer the fan auto-
matically returns to trickle.
Case 2: Automatic operation as in
case 1 with the facility to override
the humidity sensor by means of an
external switch (fi g.5) or light switch
(fi g.4), when the humidity level in the
room is lower than the selected level.
In this case, the extract fan continues
to operate for the selected period set
on the timer after the light switch has
been turned off.
ATTENTION: When the humidity rate
is above the selected value, the auto-
matic option takes precedence over
the manual.
FACTORY SETTINGS
• Airfl ow: (8l/s)
• Timer: 1 minute
• Humidity: 60% RH
SPECIFIC RECOMMENDATIONS
• If you change the settings of the
extract fan you have to handle the
microswitches in the printed circuit
board. These microswitches are
fragile and must be handled with
care.
• Do not change the setting of the hu-
midity sensor out of the room whe-
re the fan will be installed.
