[2-10 Restrictions on Refrigerant Pipes ]
1) A system that requires more than 16 BC controller ports requires two or three BC controllers (main and sub), and three pipes
will be used between the main and the sub BC controllers.
2) When connecting two sub BC controllers, observe the maximum allowable length in the table above.
3) When connecting two sub BC controllers, install them in parallel.
4) 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. )
5) Do not connect the P200 or P250 models of indoor units and other models of indoor units at the same port.
6) Group the indoor units together that connected to the same port if multiple indoor units are connected to the same port on BC
controller. Also share one thermo-stat such as on remote controller so that they turn on/off at the same time.
7) The maximum capacity of the indoor units that is connectable to the CMB-P-V-GB1 types of sub BC controllers is P350 or
below (when two GB1 type controllers are connected P350 or below for both combined).
The maximum total capacity of indoor units that is connectable to the sub BC controller CMB-P1016V-HB1 is P350 or below.
If at least one CMB-P1016V-HB1 unit is connected, the maximum total capacity of connectable indoor units to a system with
two sub controllers is P450 or below.
