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.
