• When using two controllers, only the primary controller can be set
as the main controller. In cases where two controllers are both sub
controllers, the "Main Remote Setting" is only accessible from the
primary controller.
• In cases where 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.
• If the sub controller is displayed, the main switch may not function
normally. Please verify the cable connection.
• If a remote control group is operating with multiple refrigerant systems,
the ECO function may not operate normally.
