Operation as
operation", with the facility to override the
humidistat by means of the light switch
when the humidity level in the room is
lower than the selected 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 automatic
option takes precedence over the manual

using a switch.

function" allows to delay the extractor
start-up for a period of 50 seconds. So

on if the usage time of the bathroom 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.
