1 In the case of free component multi type systems consisting of simultaneous twin, triple and quad units, connect the remote controller 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)

1 For systems containing built-in wired remote controllers (or built-in wireless receiver adapters) and consisting of simultaneous twin, triple and quad
units only, the installed remote controllers (or receiver adapters) must be connected without changing any settings. If the system consists of
different models, keep only one of the remote controllers built into the indoor units, or remove all the remote controller cables and connect them
to other models according to 1 and 2.
2 Use the wired remote controllers without setting them as the main and sub controllers.
