16.5 To connect the external outputs
FAN output (extraction fan)
The extraction FAN output is a contact on terminal X6M that closes in case a leak is
detected, or when there is a failure or disconnection of the R32 sensor in the SV
unit.
The FAN output must be used when a ventilated enclosure is required (see
"13.3To determine the required safety measures"[445]).
