3. How to operate
Before starting operation
• The choice of indoor unit operation mode is limited by the operation status
of the outdoor unit to which a given indoor unit is connected. If an outdoor
unit and some of the indoor units that are connected to the outdoor units are
already operating in the cooling mode, for example, only the cooling mode
is available for the rest of the units in the same group. If a different mode is
requested, the symbol that corresponds to the requested mode will blink,
notifying the user that the mode is currently unavailable. The same is true for
the heating mode. This restriction, however, does not apply to the models that
support a simultaneous cooling/heating function.
• The outdoor units stop when all the indoor units connected to the counterpart
outdoor units stop.
• During heating operation, even if the indoor unit is set to operation while the
outdoor unit is in defrosting operation, operation starts after the defrosting
operation of the outdoor unit has ended.

protects the machine. It automatically starts operation after the lapse of
approximately 3 minutes.

Basic operations
Pressing the
button will change the operation mode in the following order.
*1: Not all functions are available on all models of indoor units. Functions that are not available will not
appear on the display.
*2: The preset temperature for AUTO (either single or dual set point) mode will appear depending on
the indoor unit model.
AUTO (dual set point) mode:
In AUTO (dual set point) mode, the preset temperatures can be set for cooling and heating, and
operation can be switched automatically between cooling and heating depending on the room
temperature.
The preset temperatures for cooling and heating set in AUTO (dual set point) mode will be reflected
to the temperature setting for COOL/DRYING and HEAT modes.
SETBACK mode:
The SETBACK function automatically switches the operation mode between cooling and heating to
maintain the room temperature within the set temperature range.
The preset temperatures for cooling and heating set in SETBACK mode can be different from the
preset temperatures for other modes.
