1 In the case of free component multi type systems consisting of simultaneous twin, triple and quad units, connect the remote controllers to any
one of the indoor units. All the functions of the connected indoor units can be controlled even if the system consists of different models. However,
some functions may be restricted.
2 In the case of free component multi type systems consisting of simultaneous twin, triple and quad units, the indoor units should not be connected
by crossover wiring. (Prohibited)
3 Set one of the remote controllers as the main controller (factory setting) and the other as the sub controller using the remote controller's function
selection.

1 In the case of free component multi type systems consisting of simultaneous twin, triple and quad units, connect two wireless remote controller
receivers (one each) to any two of the indoor units. All the functions of the connected indoor units can be controlled even if the system consists
of different models. However, some functions may be restricted.
2 In the case of free component multi type systems consisting of simultaneous twin, triple and quad units, the indoor units should not be connected
by crossover wiring. (Prohibited)
3 In the case of "standard 1:1" connection, it is not possible to connect two remote controller receivers to the indoor units. However, with systems
consisting of simultaneous twin, triple and quad units, it is possible to connect a remote controller receiver to two indoor units. In this case, all
the pair numbers will be "0" (factory setting, no change necessary), and all the units will be turned ON/OFF simultaneously.
4 When using two or more wireless remote controllers, the display contents on the remote controllers may differ from the actual settings, since the
operation made last by any of the remote controllers will be effective.

1 In the case of free component multi type systems consisting of simultaneous twin, triple and quad units, connect both the wired remote controller
and wireless remote controller receiver to any one of the indoor units. All the functions of the connected indoor units can be controlled even if
the system consists of different models. However, some functions may be restricted.
2 In the case of free component multi type systems consisting of simultaneous twin, triple and quad units, the indoor units should not be connected
by crossover wiring. (Prohibited)
3 When using two or more wireless remote controllers, the display contents on the remote controllers may differ from the actual settings, since the
operation made last by any of the wireless remote controllers will be effective.
