Wiring diagram 3
L and N terminals are connected to live and neutral respectively. LT contact is connected to live through external switch,
light switch. The fan is always in standby mode. As 24 HOURS Mode is activated the fan runs permanently at low speed to
ensure minimum round-the-clock ventilation. As the external switch is closed the fan switches to SILENT mode. In some time
after the external switch is closed the fan reverts to the previous mode. If the temperature rises above the set point, the fan is
switched to MAX (by default) or SILENT (if set) mode. After the indoor temperature falls 2
°
C below the set temperature point,
the fan reverts to the previous mode.
