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, 2 or more units can operate simultaneously.
• When you try to operate 2 or more indoor units with 1 outdoor unit si-
multaneously, 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 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
fl
owing may be heard, they are
not malfunction. The reason is that the refrigerant continuously
fl
ows
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 tem-
perature 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
fi
xed effective temperature, cooling operation is performed
a few degrees warmer and heating operation is performed a few de-
grees cooler than the set room temperature once the temperature is
reached (automatic energy-saving operation).
