"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.
