after branching of header. When the total capacity codes of all outdoor units are 12 to below

a RBM-HY2043E or RBM-HY2083E regardless of the total capacity codes of outdoor units
at downstream side. In addition, you cannot use a branching header for the first branching
section when the total capacity codes of all outdoor units are over 26 (equivalent to HP).
