DECOR-300 H, CH, HZ, and CHZ
Models provided with an electronic humidistat which can be adjusted from 60 % to 90 % RH
(relative humidity), and with a timer, ajustable between 2 and 20 minutes.
Operation
Case 1: Automatic operation (Fig. 9).
In automatic operation, the 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. 10), 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.
ATTENTION:When the humidity 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.
The desired humidity level is selected by means of a potentiometer «% Hr» positioned on the
printed circuit board (Fig. 7) and accessible once the grille (1) has been removed.
- To increase the humidity setting turn anticlockwise (min. 60 %).
- To reduce the humidity setting turn clockwise (max. 90 %).
To set the timer, turn the potentiometer «t min.» on the printed circuit board (Fig. 7):
- To reduce the «run on» time, turn anticlockwise (min. 2 minutes).
- To increase the «run on» time, turn clockwise (max. 90 %).
Maintenance
The extractor needs only a periodical cleaning using a cloth lightly impregnated with a soft
detergent.
