20.7 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 BS unit or indoor unit).
The SVEO output is a contact on terminal X2M that closes in case of occurrence of
general errors. See
41] and
161] for errors that will trigger this output.
NOTICE
The outputs have a limited capacity of 220~240 V AC – 0.5 A.
Do NOT use the outputs as a power source. Instead, use each output to energize a
relay that controls the external circuit.
