Automatic adjustment to air humidity and
spring-return switch. The terminals L and N are
connected to live and neutral and the terminal
LT is connected to live via an external switch,
e.g. limit switch for door opening.
• The fan is as standard in SLEEP mode and
is not running.
• If 24 HOURS mode is activated the fan
runs at low speed for continuous
ventilation.
• When the spring-return switch is activated
the fan switches to QUIET mode and runs
in this mode for the set stop delay. The fan
then returns to the previous mode.
• If the humidity increases the fan switches
to MAXIMAL (standard setting) or QUIET
mode. The fan returns to the previous
mode the set time after the humidity has
stabilised.
