< Setting of the outdoor unit DIP switches >
C A U T I O N
Before modifying
the DIP switch settings, the power supply must be disconnected. Otherwise, the new setting will
not be valid.
N O T E
• While the
power remains on, the switches are disabled and the settings carried out are not valid. However,
switch DSW4, contacts 1, 2 and 4 and the pushbuttons can be used with the power supply turned on.
• Mark “■” indicates the position of the DIP switches. The figures show the position of the DIP switch once the
