1. The LED on the motherboard
The LED indicates the operating status:
green illuminated
iVent 8A ventilation control panel OK
red illuminated
error
2. The 7 segment display on the daughterboard
The 7 segment display shows the current mode:
3. The LED on the vent switch
The indicator on the vent switch can be configured on an individual basis via the Service Port Software
(see configuration), the default settings are:
4. Superior vent switch LED outlet
(Terminal 3)
This outlet switches to High (27.5 V or 24 V) as soon as the window is opened or the vent switch superior LED inlet
(Terminal 7) is High (provided that this inlet is not configured for the sun protection function: see guidance in the section
on configuration). The outlet will not be Low (0 V) until the window is completely closed (activation time reached) and the
inlet LED is Low (see section on configuration).
