in the room is lower than the selec-
ted level. In this case the extractor
continues to operate for the selected
period of time (over-run timer) after
the switch light has been switched off.
ATTENTION: When the humidity rate
is above the selected value, the auto-
matic option takes precedence over
the manual and the unit cannot then
be switched off using the pullcord.
Start-up timer function:
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 the usage time of the ba-
throom is less than 50s.
If you exceed the 50s and the humidity
level in the room is below the selected
level, the fan switches on, and when
the light switches off, runs the time
set by the timer.
This function is selected with the dip-
switch 8.
Factory settings:
• Interval function: OFF
• Interval time: 4h
• Humidistat: 60%HR
• Timer: 1 minute
• Start-up timer function: OFF
