HOW THE AIR CONDITIONER WORKS

TEMPORARY OPERATIONS

The air conditioner selects and operates in one of the
operating modes of cooling, heating (cooling only
type without) or fan only, depending on the room
temperature.
The air conditioner will control room temperature
automatically round the temperature point set by you.
If the Auto mode is uncomfortable, you can select the
desired conditions manually.

Set the TEMPORARY switch to the AUTO position in order
to start the automatic operation.
The COOL position is provided for test runs of the unit, and
automatic temperature control is cut off at this position.
Never use the position for ordinary operation.

When your 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 1 C after 1
hour and by 2 C 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.)

The dry mode will automatically select the cooling dry
operation based on the difference between the set
temperature and the actual room temperature.

This function is used to operate the unit temporarily in case
you misplace the remote controller or its batteries are
exhausted.

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.
