3. Operation

■
About the operation method, please refer to the operation manual that comes
with each remote controller.
3.1. Turning ON/OFF
Note:
Even if you press the ON/OFF button immediately after shutting down the op-
eration is progress, the air conditioner will not start for about 3 minutes. This
is to prevent the internal components from being damaged.
3.2. Operation mode select
Cool/ Dry/ Fan/ Heat/ Automatic (cool/ heat)/ ventilation mode are available.
Note:
●
Heat and Automatic modes can not be available for cooling only units.
●
Ventilation mode: only indicated on the following condition. Wired remote
controller is used and LOSSNAY is connected.
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 simulta-
neously, 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 in flashing.
In this case, please set all the indoor units to the same operation mode.
• There might be a case that the indoor unit, which is operating in
mode. Cannot change over to the operating mode (COOL ↔ HEAT) and be-
comes a state of standby.
• When indoor unit starts the operation while the defrosting of outdoor unit is being
done, it takes a few minutes (max. about 15 minutes) to blow out the warm air.
• In the heating operation, though indoor unit that does not operate may get warm
or the sound of refrigerant flowing may be heard, they are not malfunction. The
reason is that the refrigerant continuously flows into it.
Automatic operation
■
According to a set temperature, cooling operation starts if the room temperature
is too hot and heating operation starts if the room temperature is too cold.
■
During automatic operation, if the room temperature changes and remains 2 °C, 4 °F
or more above the set temperature for 15 minutes, the air conditioner switches
to cooling mode. In the same way, if the room temperature remains 2 °C, 4 °F or
more below the set temperature for 15 minutes, the air conditioner switches to
heating mode.
Cooling mode
15 minutes (switches
from heating to cooling)
15 minutes (switches

■
Because the room temperature is automatically adjusted in order to maintain
a fixed effective temperature, cooling operation is performed a few degrees
warmer and heating operation is performed a few degrees cooler than the set
room temperature once the temperature is reached (automatic energy-saving
operation).
3.3. Fan speed setting

●
The number of available fan speeds depends on the type of unit connected.
●
In the following cases, the actual fan speed generated by the unit will differ

2. When the temperature of the heat exchanger is low in the heating mode.
(e.g. immediately after heating operation starts)
3. In HEAT mode, when room temperature is higher than the temperature
setting.
4. When the unit is in DRY mode.
3.4. Airflow direction setting
Note:
●
During swing operation, the directional indication on the screen does not
change in sync with the directional vanes on the unit.

1. When the unit is in "STAND BY" or "DEFROST" states.
2. Immediately after starting heater mode (while the system is waiting for
the mode change to take effect).
3. In heat mode, when room temperature is higher than the temperature
setting.
3.5. Ventilation
For LOSSNAY combination
●
The following 2 patterns of operation is available.
