*1. When the capacity of the connected indoor units is P200 or above, use the figures in the parentheses as a reference.
1) To connect the P100 through P140 models of indoor units, use an optional junction pipe kit (Model: CMY-R160-J1) and merge
the two ports before connecting them. (In that case, set DIP SW4-6 on the BC controller to ON.)
It is also possible to connect the P100 through P140 models of units to a port, although the cooling performance will somewhat
decrease. (In that case, set DIP SW4-6 on the BC controller to OFF.)
(The factory setting for DIP SW4-6 is OFF. )
2) Do not connect the P200 or P250 models of indoor units and other models of indoor units at the same port.
3) All the units that are connected to the same ports can only be operated in the same operation mode (cooling/heating).
4) Do not use the existing Y-shaped twinning pipe.
Make sure to change the twinning pipe to the one for use with R410A.
If the existing twinning pipe is T-shaped, there is no need to change.
