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.
