9-3. 2-REMOTE CONTROLLER OPERATION
(1) 2 Wired Remote Controllers
(R: Wired remote controller)
Slim Air Conditioner System
Standard 1:1
Simultaneous Twin

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.
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 (initial setting) and the other as the sub controller using the remote controller's function
selection.

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
different models.
2
In the case of free component multi type systems consisting of simultaneous twin units, the indoor units should be connected by crossover wiring.
In the case of "standard 1:1" connection, it is not possible to connect 2 remote controller receivers to the indoor units. However, with
3
systems consisting of simultaneous twin units, it is possible to connect a remote controller receiver to two indoor units. In this case, all the
pair numbers will be "0" (initial 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 last operation made by any of the remote controllers will be effective.
