not included with the product).
Stop delay timer (part index suffix ‘T’).
Connect the air exhaust fan with the
stop delay timer (a stop delay switch) as
shown in the electrical wiring diagram,
see
Fig. 4.
The stop delay time can be set with a
potentiometer knob on the electronic
module of the stop delay timer. The
minimum stop delay time is set at
3 min. with the potentiometer
knob rotated counter-clockwise
to stop. Turn the potentiometer
knob clockwise to set a longer
stop delay time accordingly.
The maximum stop delay time
setting is 30 min. The stop delay
time is adjusted in infinite increments.
The stop delay time is counted
down from the time the air exhaust
fan senses the indoor lights
are off or turning the on/off
switch off.
Humidity sensor (part name suffix ‘H’).
Connect the air exhaust fan with the
air humidity sensor (hygrostat) and
timer as shown in the electrical wiring
diagram in
Fig.4 or Fig.5.
The air humidity sensor operating range
is 40% to 90% of relative humidity. This
accessory option includes the stop delay
timer. The operation of the air exhaust
fan with these optional accessories will
depend on the power supply connection
method. If connected as shown in
Fig.5, the air exhaust fan will start
automatically when the air humidity
level exceeds the start threshold of the
humidity sensor. Next, the air exhaust
fan will stop when the air humidity level
is reduced below the stop threshold,
plus the stop delay time set with the
stop delay timer.
If connected as shown in Fig.4, the air
exhaust fan can also be started with its
standard light sensor (by turning off
the indoor lights) or operating the
separate on/off switch. When the
indoor light is off or the on/off
switch is turned off, the air exhaust
fan will stop after the stop delay
time set with the potentiometer if the
humidity level in the room is below the
level preset on the potentiometer. The
humidity detection system is the master
system.
CAUTION: When the green diode loc
ated
in the electronic system is on, it means
that the humidity level in the room is
higher than the preset on the
potentiometer controlling the humidity
level adjustment. As long as the diode is
on, the fan will not start counting down
the stop delay after which the fan is
switched off. It will take place only after
the humidity level in the room drops and
the green diode goes off.
INSTALLATION
The fan shall only be installed,
connected to electrical mains and
commissioned for use by qualified
personnel in accordance with applicable
laws!
Assembly
• Precisely determine where the fan will
be installed.
• Prepare the power cord. Use NYM-O
2x1.5 mm² (H07V-K 2x1.5mm²) or
NYM-O 3x1.5 mm² (H07V-K 3x1.5mm²)
with a maximum outside diameter of
7.5 mm, depending on the version of the
equipment.
NOTE: Before starting work, make sure
that the power cord is not live.
• Measure and drill holes for the fan
and ø6 mm wall plugs included with
the product.
• Remove the front clip-on panel (1).
• Remove the front clip-on frame (2)
of the fan.
• Run the power cord in double
