1 In the case of free component multi type systems consisting of simultaneous twin units, connect the remote controllers to each indoor unit.
All the functions of the connected indoor units can be controlled even if the system consists of different models. However, some function may be
restricted.
2 In the case of free component multi type systems consisting of simultaneous twin units, the indoor units should be connected by crossover wiring
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 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 differen
models. However, some functions may be restricted.
2 In the case of free component multi type systems consisting of simultaneous twin units, the indoor units should be connected by crossover wiring
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 system
consisting of simultaneous twin units, it is possible to connect a remote controller receiver to two indoor units. In this case, all the pair number
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.
