If simultaneous twin or triple or quad, connect 2 wireless remote controller receivers (one each) to any 2 of the indoor units. All the functions
of the indoor unit can be controlled even if different models (different types) are mixed.
Do not use crossover wiring among indoor units with simultaneous twin, triple, quad units. (Prohibited item.)
In the case of "standard 1:1" connection, it is not possible to connect 2 remote controller receivers to the indoor units. However, with systems
consisting of simultaneous twin or triple or quad units, it is possible to connect a remote controller receiver to 2 indoor units. In this case, all the
pair numbers will be "0" (intial setting, no change necessary), and all the units will be turned ON/OFF simultaneously.
When using 2 or more wireless remote controllers, the display contents on the remote controllers may differ from the actual settings, since the
operation mode last by any of the remote controllers will be effective.
