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  and  time delay are set by means of adjuster positioned 
on the printed circuit board (fig.10) and accessible once the grille (1) is removed. 
 
The humidity is set by the 

adjuster “%HR”: 

To increase the humidity setting turn anticlockwise (min.60 %) 

To reduce 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).
