Caution for switch operations
 MA remote controller
¥ Be sure to shut off power source before setting switches. If operated with the power source on, the
switch may not operate properly.
¥ When connecting only one remote controller to one group, it becomes the main remote controller.
When connecting two remote controllers to one group, set one remote controller as the main remote controller
and the other as the sub remote controller.
¥ No unit with an identical unit address can exist in the same air conditioner system. If set erroneously,
the system will not operate.
¥ The factory setting is Main .
