"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.
When, on he contrary, the extract fan
never switches on because the humidity
level is always very low or it is
improperly

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.

over the manual and the unit cannot

Start-up timer func ion:
In this operation, the "start-up timer
function"
allows to delay the extractor
start-up for a period of 50 seconds. So
that, for example, the fan does not
switch on if
he usage time of the
bathroom is less than 50s.
If you exceed the 50s, the fan switches
on, and when the light switches off, runs
the time set by the timer.
This func ion is selected with the dip-
switch 8.
EcoAIR MLC
EcoAIR LC version similar to H model,
fitted wi h an internal pull cord switch to
operate the boost when the humidity
level is below the set point (fig.5)
When switching off the internal pull cord
switch, the fan continues to operate at
boost the time set by the timer then runs
at trickle speed, unless the humidity level
exceeds the set point.
