To connect the external outputs
SVS and SVEO output
The SVS and SVEO outputs are contacts on terminal X2M.
The SVS output is a contact on terminal X2M that closes in case a
leak is detected, failure or disconnection of the R32 sensor (located
in the SV unit or indoor unit).
The SVEO output is a contact on terminal X2M that closes in case of
occurrence of general errors. See
