In the case of single refrigerant system, the refrigerant
address is "00" and no operation is required. Simultaneous
twin, triple and quadruple units belong to this category
(Single refrigerant system).

Up to 16 refrigerant systems (16 outdoor units) can be
connected as a group by 1 remote controller. To check or
set the refrigerant addresses.
