19.6 To perform a SV/indoor unit
connection check
This test run can be performed to confirm if wiring and piping
connections between indoor units and SV units are matching.
For the safe operation of the system, it is mandatory to confirm the
wiring and piping connections between the indoor units and SV

automatic check. Consult this chapter in the Installer and User
Reference guide for extra information.
