3-36. When Using Wireless Remote Controller Instead Of Wired Remote Controller

When the wireless remote controller is to be used, slide the switch on the indoor unit control PCB.

•If this setting is not made, an alarm will occur. (The operation lamp on the display blinks.)

•This setting is not necessary if both the wired remote controller and wireless remote controller are used.

•The location of the switch varies depending on the type of PCB used. Check the model name before making the setting.
