When the set temperature is to be changed:
TOO
WARM
• Press the button to lower the temperature. One press lowers the temperature by about 1°C.
TOO
COOL
• Press the button to raise the temperature. One press raises the temperature by about 1°C.
In HEAT operation
• If the air conditioner absorbs too much heat from the air, it may be overloaded. Following a judgement made by the
microprocessor, the fan in the outdoor unit is automatically stopped to protect the air conditioner.
When the outdoor unit's fan is stopped, frost may form on the outdoor unit, but this is not a problem.
In DRY operation
• The temperature control (temperature setting) cannot be done.
• The room temperature is slightly lowered in this operation mode.
■
The details of the display on the indoor unit are explained on page 6.
NOTE:
When the ambient temperature is too high, the room temperature may not reach the set temperature since the unit
operates to cool the room under a high load.
Information for multi system air conditioner (Outdoor unit: MXZ series)
Multi system air conditioner (Outdoor unit: MXZ series) can connect two or more indoor units with one outdoor
unit. According to the capacity, two or more units can operate simultaneously.
• When you try to operate two or more indoor units with one outdoor unit simultaneously, one for the cooling and the
other for heating, the operation mode of the indoor unit that operates earlier is selected. The other indoor units that will
start the operation later cannot operate, indicating an operation state. (Refer to the table of Operation Indicator lamp on page 6.)
In this case, please set all the indoor units to the same operation mode.
• When indoor unit starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max.
10 minutes) to blow out the warm air.
• In the heating operation, the indoor unit that does not operate may get warm or the sound of refrigerant flowing may
be heard. This is not a malfunction since the refrigerant continuously flows into the indoor unit that does not operate.

NOTE:
• In the cooling operation, when the air conditioner is operated with setting the horizontal vane to
1 hour, the AIR FLOW direction is automatically set to horizontal to prevent condensed water from dropping.
• Adjust the vertical AIR FLOW direction using the remote controller. Moving the horizontal vane manually can cause trouble.
• In the heating operation, if the air flow temperature is too low or when defrosting is being done, the horizontal vane
position is set to (1).
Auto air flow direction control operation
When the AUTO mode is selected with the
to correspond to the operation mode for effective operation.
(1) HEAT: When the air flow temperature is too low, the air is blown out horizontally.
When the air flow temperature rises, the air is blown out downwards.
(2) COOL, DRY: The air is blown out horizontally.
(3) FAN: The air is blown out downwards.
