Start-up timer function:
In this operation, the “start-up ti-
mer function” allows you to delay
the extractor start-up for a period
of 50 seconds. So that, for exam-
ple, the fan does not switch on if
the usage time of the bathroom is
less than 50s.
If you exceed the 50s, the fan swit-
ches on, and when the light swit-
ches off, runs the time set by the
timer.
This function is selected with the
dip- switch 8.

function” allows the fan to delay the
start-up for a period of 50 seconds.
So that, for example, the fan does

bathroom is less than 50s.
If you exceed the 50s, the fan swit-
ches on, and when the light swit-
ches off, runs on for the time set by
the timer.
This function is selected with the
dip- switch 8.
