depending on the desired function, as detailed below:
1 Humidity control only, see diagram 1
The fan is connected to constant phase (L) and
neutral (N) for automatic humidity control.
The timer can be activated manually by installing a pull
cord and pulling it (see page 8).

diagram 2
The fan is connected to constant phase (L) and
neutral (N) for automatic humidity control.
Switched live (SL) is connected to activate the fan's
timer, i.e. when the bathroom light is switched on. This
option provides a 90-second start delay.
3 Humidity c timer with retractive switch, see
diagram 3
