Note: The SV1A unit requires no DIP switch setting. The factory
default setting can be used for any indoor unit connected to the
branch port.

branch pipe ports A and B, but NOT
connecting an indoor unit to branch pipe
ports C and D.

15.6 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 "12.3 To determine the required safety
measures" [ 4 14]).
