Note
I
1) To connect the P72 or P96 models of indoor units, use an optional junction pipe kit (Model: CMY-R160-J).
2) Do not connect the P72 or P96 models of indoor units and other models of indoor units at the same port.
3) Note the following when connecting multiple indoor units to a single port.
'Those indoor units connected to the same port must be installed in the same room.
'Set the indoor temperature via the connected remote controller, and when connecting multiple remote controllers, configure
these controllers as a group by making appropriate settings. These indoor units can only be operated in the same mode.
