Automatic Operation
When you set the air conditioner in AUTO mode, it will automatically select coo-
ling, heating(cooling/heating models only), or fan only operation depending on
what temperature you have selected and the room temperature.
The air conditioner will control room temperature automatically round the tem-
perature point set by you.
If the AUTO mode is uncomfortable, you can select desired conditions
manually.
Economic Operation
When you push ECONO button during cooling, heating (cooling only type
without),or AUTO operation, the air conditioner will start following operation. The
fan speed will be automatically controlled .In the operation suppression zone
where capacity is kept to the minimum, overcooling is prevented by raising the
temperature setting by 1ºC after 1 hour and by 2ºC after 2 hours of operation. The
room temperature is thus regulated between the operation suppression zone and
the set temperature.(It depends on the outdoor temperature.)
Drying Operation
The dry mode will automatically select the drying operation based on the diffe-
rence between the set temperature and the actual room temperature.
The temperature is regulated while dehumidifying by repeating turning on and
off of the cooling operation or fan only. The fan speed indicator will display
AUTO and low speed will be used.
HOW THE AIR CONDITIONER WORKS
To achieve optimal performance, please note the following:
Adjust the air flow direction correctly so that it is not directed on people.
Adjust the temperature to achieve the highest comfort level. Do not adjust the unit to excessive temperature levels.
Close doors and windows on COOL or HEAT modes, or performance may be reduced.
Use TIMER ON button on the remote controller to select a time you want to start your air conditioner.
Do not put any object near air inlet or air outlet, as the efficiency of the air conditioner may be reduced and the air conditioner
may stop running.
Clean the air filter periodically, otherwise cooling or heating performance may be reduced.
Do not operate unit with horizontal louvre in closed position.
