-  In  order  to  ensure  correct  measurement  of  humidity  levels,  the  fan  must  be 

installed in an area where there is good air circulation. 

-  Ensure that  the fan is inside the room  that it is to be installed in  when setting 

the humidity level. 

-  If  the  humidity  level  is  consistently  above  90%,  the  fan  will  continue  to  run 

without stopping. 

 
 
Operation 
 
Case 1: Automatic operation (Fig.8). 
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 with manual override. 
Automatic  operation  as  in  case  1,  but  with  the  facility  to  override  the  humidistat 
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 
period set on the timer, after the light switch has been switched off. 
 

ATTENTION:  When  the  humidity  rises  above  the  selected  value,  the 
automatic  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. “

ATTENTION: When the fan is operating on run-on time phase, it must finish 
before adjusting to a new setting.
