button simultaneously.
(Press and hold for 4 seconds or longer.)
2. Next, press either the temperature setting
or
button.
(Check that the item code is “A1”.)

button to set the system No. to perform automatic address setting.
4. Then press the
button.
(Automatic address setting for one refrigerant system begins.)
(When automatic address setting for one system is completed, the system returns to
normal stopped status.) <Approximately 4 – 5 minutes is required.>
(During automatic address setting, “
