When setting the operating mode with the Operating Mode Switch., the air conditioner must be turned on and off with the centralized controller button, in order to deliver the content of the operating status to each indoor unit.
When using a heat pump model, the indoor units connected to one outdoor unit cannot have 'Mixed Operations'.

- 'Mixed Operation' means that the indoor units connected to one outdoor unit show different kinds of operating modes. In other words, certain indoor units connected to one outdoor unit operate in the heating mode, while other indoor units operate in the cooling mode.

The operating mode can be affected by the operating status of the indoor unit and the centralized controller.

◆The air conditioner can operate in a mode other than the one specified with the Operating Mode Switch.

When operating the indoor units in the Cool or Heat Mode

1 If the operating mode that was selected when the unit was last used is the same as the centralized controller's operating mode, the indoor unit will operate in the operating mode that was selected when the unit was last used.

If the indoor unit is in the Heat operating mode with a set temperature of 30^(86^) and the centralized controller is in the Heat operating mode with a set temperature of 27^(81^) , the air conditioner will start its operation in the heating mode with a set temperature of 30^(86^) .

2 If the operating mode that was selected when the unit was last used is different from the centralized controller's operating mode, the indoor unit will operate in the operating mode of the centralized controller.

If the indoor unit is in the Dry operating mode with a set temperature of 24^(76^) and the centralized controller is in the Heat operating mode with a set temperature of 27^(81^) , the indoor unit will operate in the Heat operating mode with a set temperature of 27^(81^) .

When operating the indoor units in the Auto Mode

If the air conditioner is turned on, it will operate in the operating mode that was selected when the unit was last used. However, when the power is turned on for the first time after installing the system, the air conditioner will operate in the Auto operating mode with a set temperature of 24^(76^) .
