primary controller.
• In case the primary controller is a “Main Controller” and the secondary
controller is a “Sub Controller”, when the primary controller and the
secondary controller are changed by the function selection, Main and
Sub controllers will also be switched simultaneously.
• In case only sub controllers are setup for one refrigerant cycle system,
the main remote controller may not operate normally. In this case,
check the connection wiring on the related wired controller.
• If a remote control group is operating with multiple refrigerant systems,
the ECO function may not operate normally.
