Window contact
You can connect a window contact to terminal X18. The window
contact is required for passive cooling. The appliance checks
whether a window contact is connected and activated at X18.
The window contact must be an N/O contact.
10.5 Overflow apertures
Create suitable overflow apertures in the supply air area or over-
flow area. This is absolutely essential, since otherwise passive
cooling is not possible.
