Cooling / Heating operations
Each unit can be controlled individually. However,
indoor units connected to the same outdoor unit
cannot perform cooling and heating simultaneously.
When you attempt simultaneous operation, indoor
units performing cooling are stopped, and the running
preparation indicator
is displayed on the remote
controller.
An indoor unit performing heating continues running.
When you attempt an operation without the confi gured
settings, the running preparation indicator
is
displayed on the remote controller and operation stops.
If operation is fi xed to cooling or heating by the air
conditioner administrator, only the confi gured settings
apply to the operation.

Characteristics of heating
(For heat-pump model only)
• Air does not come out immediately after heating
starts. Heated air comes out after 3 to 5 minutes
(depending on the room/outside temperatures), after
the indoor heat exchanger warms up.
• When the outside temperature increases, the
outdoor unit may stop.
