Wiring diagram 4
L and N terminals are connected to live and neutral respectively. LT terminal is connected to live through the external
momentary switch that is activated by opening a door. The fan is in standby mode and does not run. As 24 HOURS Mode is
activated the fan runs permanently at low speed to ensure minimum round - the - clock ventilation. As the external momentary
switch is closed the fan switches to SILENT mode for the period adjusted in the off - delay timer. After that the fan reverts to
standby mode. As motion sensor is activated (for Aura Smart MSHT only) the fan switches to SILENT mode. After no motion is
detected the fan reverts to standby mode. As humidity level increases the fan switches to MAX mode (by default) or to
SILENT mode. After humidity level drops the fan reverts to standby mode.
