Connect the electrical wiring as set out
below and then mount the protection
grille (1) and tighten the screw (2).
Electrical connection
The DECOR-100 is an extractor
designed for a single phase supply, with
voltage and frequency as indicated on the
rating plate of the unit. The units are
manufactured with double electrical
insulation (Class II) and therefore they do
not need an earth connection.
The electrical installation must include a
double pole switch with a contact
clearance of at least 3 mm.
The electrical cable must enter the
DECOR-100 through one of the cable
point (5).
Once the cable has been introduced
proceed using the electrical wiring
diagram applicable to the selected model.
DECOR S, C and CZ
These models use the following
diagrams:
Fig.3: Fan operating through the light
switch.
Fig.4: Fan operating through an
independent switch.
DECOR CR and CRZ
These models are fitted with an
adjustable timer. The timer enables the
fan to continue running for the selected
period after the switch has been turned
off.

independent switch.

switch
The desired run-on time is selected by
means of an adjuster positioned on the
printed circuit board (fig. 7) and
accessible once the grille (1) has been
removed:
- To reduce the run-on time, turn
anticlockwise (min. 1 minute)
- To increase the run-on time, turn
clockwise (max: 30 minutes).
DECOR CH and CHZ
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.
Specific recommendations
- If changing the settings of the fan you
have to handle the controls located on
the PCB. These adjusters are fragile
and must be handled with care.
- For humidity measurement is correct
we need the fan is installed in an area
where there is good air circulation.
- Do not adjust the humidity outside the
room where the vent should be
installed.
- If the humidity level is consistently
above 90% RH, the fan will not stop.
Operation
Case 1: Automatic operation (fig.8)
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.
Case 2: Automatic operation as in case 1
with the facility to override the hygrostat
by means of the light switch (fig.6), 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.
ATENTION: When the humidity rise
above the selected value, the
automatic option takes precedence
