The desired run-on time is selected by
means of an adjuster positioned on the
printed circuit board (fig. 7) and accessi-
ble once the grille (1) has been removed:
- To reduce the run-on time, turn anti-
clockwise (min. 1 minute).
- To increase the run-on time, turn
clockwise (max: 30 minutes).
DECOR H, CH, HZ, 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 cor-
rect we need the fan is installed in
an area where there is good air cir-
culation.
- 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 op-
erate automatically when the humidity
level in the room is higher than the set
level. The extractor will stop automat-
ically when the humidity drops below
the selected level and after the select-
ed period set on the timer.
Case 2: Automatic operation as in case
1 with the facility to override the hy-
grostat 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 auto-
matic option takes precedence over
the manual and the unit cannot then
be switched off using a switch.
SETTINGS
The fans are set to operate at 60%
relative humidity and with 2 minutes
run-on time.
If the humidity in the room is lower
than 60%, the fan will not turn on. If
it is higher, the fan will operate until
the humidity level drops below 60%RH
and then runs for the length of time
set by the timer. The desired humidity
level and time delay are set by means
of adjusters positioned on the printed
circuit board (fig. 9) and accessible
once the grille (1) has been removed.
The humidity is set by the adjuster "%
Hr".
- To reduce the humidity setting turn
anticlockwise (min.60 %)
- To increase the humidity setting turn
clockwise (max. 90 %)
The timer is set by the adjuster "t
min."
- To reduce the run-on time, turn anti-
clockwise (min. 2 minutes).
- To increase the run-on time, turn
clockwise (max: 20 minutes).
