Unit Number Setting
The indoor unit numbers are set by the auto-address function. Therefore, an indoor unit number setting
is not required. If the indoor unit number is fixed, set the unit number of all indoor units respectively and
serially. It is recommended that the unit number settings begin with “1”. The setting is set not to overlap
the unit number.
