Safety Instructions
Caution! All work on the time lag unit
(mains connection and setting of minia-
ture switches) must only be carried out
when power supply has been completely
disconnected!
Ensure all connection lines are de-
energized before connecting the fan unit
to the supply voltage!
(Disconnection from mains with at least 3
mm contact opening, e.g. electric fuse).
Each circuit connected to the fan must be
equipped with residual current protection
(e.g. RCD switch)!
Electrical connections must only be car-
ried out by qualified staff!
Additional installations and electrical components in the
fan are not admissible.
Connection diagrams for other fan functions available on
request.

Operating the Unit
You can switch the following functions
using the miniature switches:
Interval switching
If the interval switching is activated, the
interval meter triggers a start of the fan
every 4 h after the previous time the fan
was switched off. The ventilation period is
then 30 minutes.
Time lag
The fan continues to operate after switch-
ing off for the respective time set.
Inverse operation
Fan only starts to operate after room
lighting has been switched off. The venti-
lation period is then 30 minutes.
Switch-on delay
Fan only starts 120 sec. or immediately
after being switched on.
Simultaneous installation of basic ventila-
tion in continuous operation of the fan and
of the time lag for ventilation on demand
or full load mode (interval/inverse and
also time lag switching) is possible.
