Information for multi system air conditioner (Outdoor
unit: MXZ series)
s s s s s Multi system air conditioner (Outdoor unit: MXZ series) can con-
nect 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 opera-
tion 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
I According to a set temperature, cooling operation starts if the room tem-
perature is too hot and heating operation starts if the room temperature
is too cold.
I During automatic operation, if the room temperature changes and re-
mains 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 tem-
perature remains 2 °C or more below the set temperature for 15 min-
utes, the air conditioner switches to heating mode.
Cooling mode
15 minutes (switches
from cooling to heating )
I 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).
