Automatic operation: 
The  extractor  is  connected  to  the  main 
supply  with  only  two  wires.  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  (-5%  or  +10%)  and  after 
the  selected  period  set  on  the  over-run 
timer. 

"Interval” functions: 
This  function  is  useful  when  the  extract 
fan is installed in very wet (near the sea) 
or the ambiance exceeds the set level for 
a very long time. To prevent the fan to run 
for hours without stopping, the "Interval" 
function  allows  the  fan  to  switch  off 
automatically  one  hour  after  it  began  to 
run.  The  extractor  keeps  switched  off 
during the set time for interval function. If 
the  humidity  level  is  still  above  the  set 
level  when  the  time  interval is  over,  the 
extract  fan  switches  on  again  and  run 
during  one  hour.  To  select  this  function 
put the dip-switch 1 to position "ON”  

To adjust the set time for interval function, 
use the dip-switches 2 and 3. 

When,  on  the  contrary,  the  extract  fan 
never switches on because the humidity 
level is always very low or it is improperly 
installed  (above  heating  appliance, 
behind  a  door,  in  an  area  with  no  air 
movement)  putting  the  1  dip-switch 
interval function to position "ON", the fan 
switches on automatically during 1 hour 
and then it keeps switched off during the 
set time for interval function. This function 
causes  the  fan  to  run  whatever  the 
humidity level. 

To select this function put the dip-switch 
1 to position "ON”  
To  adjust  the  pre-set  time  for  interval 
function, use the dip-switches 2 and 3.
