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. Accord
ing 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 in blinking.
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 (AUTO)
mode. Cannot change over to the operating mode (COOL HEAT) and
becomes 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  °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  °C, 4 °F or more below the set
temperature for 15 minutes, the air conditioner switches to heating
mode.

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
from the speed shown the remote controller display.
1. When the unit is in "STAND BY" or "DEFROST" states.
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 dose not
change in sync with the directional vanes on the unit.
Available directions depend on the type of unit connected.
In the following cases, the actual air direction will differ from the direction
indicated on the remote controller display.
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.
