Multi system operation
Two or more indoor units can be operated by one outdoor unit. When several indoor
units are operated simultaneously, cooling and heating operations cannot be done at
the same time. When COOL is selected with one unit and HEAT with another or vice
versa, the unit operated later becomes standby mode.
Water may condense when HEAT is operated with other units within 3 hours after
COOL/DRY operation is stopped.
To prevent water condensation, perform HEAT with temperature set to 61°F (16°C)
for about 30 minutes after COOL/DRY operation.

(COOL↔HEAT) when the room temperature is about 4°F (2°C) away from the set
temperature for more than 15 minutes.
Note:
During multi system operation, the unit may not be able to switch operation mode
between COOL and HEAT. In this case, the indoor unit becomes standby mode
(Refer to table of Operation indicator lamp).
COOL mode

Note:
Do not operate COOL mode at low outside temperature (less than 14°F [-10°C]).
Water condensed in the unit may drip and wet or damage furniture, etc.

function" automatically starts operation in the same mode as the one set with the remote
controller just before the shutoff of the main power. When timer is set, timer setting is
cancelled and the unit starts operation when power is resumed.
If you do not want to use this function, please consult the service representative
because the setting of the unit needs to be changed.
