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.

During multi system operation, the unit may not be able to switch opera-
tion mode between COOL and HEAT. In this case, the indoor unit be-
comes standby mode (Refer to table of Operation indicator lamp).

If you do not want to use this function, please consult the service repre-
sentative because the setting of the unit needs to be changed.
