DECOR-100 CHZ
These models are provided with an
electronic humidistat which can be
adjusted between 60, 70, 80 or 90%
RH (relative humidity) and with an
automatic run-on-timer, adjustable
between 5, 10 or 20 minutes. Both
humidistat and timer adjustments
can be made using the correspond-
ing adjustment dials without the
need to remove the front grille of
the fan.
HUMIDISTAT
The desired humidity level is se-
lected by means of an adjustment
dial (6) located on the side of the
fan casing. The corresponding
relative humidity level, 60-70-80 or
90%, is then visually indicated via
one of four neon lights. All models
are factory set as standard to a 90%
relative humidity level.
OVER-RUN TIMER
All models include an over-run timer
which enables the fan to continue
to operate after the primary switch
has been disconnected (switched
off). The over-run time should be
set in accordance with local and
national building code regulations
and also with respect to the pro-
portion of humidity encountered.
For brief periods of operation the
over-run time should be set to the
minimum period of 2 minutes. For
prolonged periods of operation the
over-run time should be set to the
maximum period of 20 minutes.
This will ensure the most ef cient
extraction of the humid air whilst
saving time on fan operation.
Operation
Case 1: Automatic operation( g.5)
In automatic operation, the humi-
distat causes the extractor to oper-
ate automatically when the humidity
level in the room is higher than the
pre-set level. The extractor will
stop automatically when the hu-
midity drops below the selected
level and after the selected pe-
riod set on the over-run timer.
Case 2: Automatic operation as
in case (1) but with the facility to
override the humidistat by means
of the light switch ( g.4), 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
of time (over-run timer) after the
switch light has been switched off.
• If the period of operation is
less than 50 seconds then the
overrun timer will not operate.
• If the period of operation is more
than 50 seconds then the over-
run timer will operate in accord-
ance to the pre-set time period.
ATTENTION: When the humid-
ity rate is above the selected
value, the automatic option
takes precedence over the
manual and the unit cannot
then be switched off using a
switch.
Maintenance
The extractor fan only requires
periodical cleaning using a cloth
lightly impregnated with a soft
detergent.
