the set temperature.
HEAT mode changes to COOL mode when about 15 minutes have passed with the room temperature 2°F (1°C) above
the set temperature.
NOTE1
If two or more indoor units are operating in multi system, there might be a case that the indoor unit, which is operating in i--_
(AUTO), cannot change over to the other operating mode (COOL _ HEAT(MSZ)) and becomes a state of standby.
Refer to NOTE2 "FOR MULTI SYSTEM AIR CONDITIONER".
NOTE2
FOR MULTI SYSTEM AIR CONDITIONER
OUTDOOR UNIT: MXZ series
Multi system air conditioner can connect two or more indoor units with one outdoor unit.
• When you try to operate two or more indoor units with one outdoor unit simultaneously, one for the cooling and
the others for heating, the operation mode of the indoor unit that operates first is selected. Other indoor units
cannot operate, and operation indicator lamp flashes as shown in the figure below. In this case, please set all the
indoor units to the same operation mode.

• When indoor unit starts the operation while the defrosting of outdoor unit is being done, it takes a few minutes (max.
10 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 flow-
ing may be heard, they are not malfunction. The reason is that the refrigerant continuously flows into it.
