▶ 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 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
(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 2 °C 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 or more below the set temperature for 15
minutes, the air conditioner switches to heating mode.

■ Because the room temperature is automatically adjusted in order to
maintain a fixed effective temperature, cooling operation is performed

degrees cooler than the set room temperature once the temperature
is reached (automatic energy-saving operation).
