Auto restart function
If a power failure occurs or the main power is turned off during operation, “Auto
restart function” automatically starts operation in the same mode as the one set
with the remote controller just before the shutoff of the main power. When
timer is set, timer setting is cancelled and the unit starts operation when power
is resumed.
If you do not want to use this function, please consult the service repre-
sentative because the setting of the unit needs to be changed.
Multi system operation
Two or more indoor units can be operated by one outdoor unit. When several
indoor units are operated simultaneously, cooling and heating operations cannot
be done at the same time. When COOL is selected with one unit and HEAT with
another or vice versa, the unit operated later becomes standby mode.
