Automatic Operation
As shown in Figures 1 and 2, Automatic Operation mode selects the operation based on the room temperature data (Ta) when
operation begins.
The operation mode is selected again after the compressor has remained stopped for 15 minutes.
Hi POWER operation
When you press the Hi POWER button during cooling, heating or A operation, the air conditioner starts the following operation.
• Cooling operation
The cooling operation is performed at 1°C lower than the temperature setting.
The fan speed is also set to high*.
* The noise level raises, according to the fan speed.
• Heating operation (heat pump models)
The heating operation is performed at 2°C higher than the temperature setting.
The fan speed is automatically switched according to the operating condition.
SLEEP MODE operation
The air conditioner automatically controls the room temperature, air flow and noise level, to prevent overcooling in summer and
maintain a warm and comfortable room in winter.
Dry operation (
)
The dry mode automatically selects the cooling dry operation based on the difference between the temperature setting and the actual
room temperature.
The fan speed indicator shows AUTO, and low speed is used.
HOW THE AIR CONDITIONER WORKS
INFORMATION
INFORMATION
• The power and noise level are reduced during sleep mode, so the room may not be cooled (or heated: heat pump models
only) sufficiently if the mode is used for a long period of time.
• The sleep mode cannot be used during dry operation, PURE operation (independent operation) or fan only operation (cooling-
only models only).
(PURE operation (independent operation) is when the PURE button is pressed while the air conditioner is stopped to perform
PURE operation by itself. The air conditioner does not operate at this time.)
• If the FAN button is pressed during sleep mode, the sleep mode is canceled.
• Sleep mode is not a timer operation.
