Operation
l
Precedence-room setting
When setting the preference-room during installation, the
indoor unit's operation mode always takes priority.
When the precedence-setting room unit is operated in
POWERFUL mode, there are times that air conditioners in other
rooms will temporarily stop in order to centralize power to the
unit in the room.
Please adjust the precedence-room setting to match your life
style. Moreover, for precedence-room settings, please consult
the service shop where you bought the unit.
Precedence-room setting is applied to only 4MX80, 4MK90.
l
COOL/HEAT mode
This mode is used to set the unit to only cool or heat. For
information on using this mode, consult the service shop where
you bought the unit.
COOL/HEAT mode is applied to only 4MX80, 4MK90.
Note for Multi
System
NOTE
<Note for heat pump multi system>
When two or more indoor units have no precedence-room
settings and are set to modes that differ from each other, the
indoor unit which is operated first activates, while the other
indoor unit does not activate and the OPERATION lamp blinks.
(This is not a malfunction.)
An indoor unit that is not in operation will automatically start
and operate in the mode in which a previously operated indoor
unit was stopped. However, if the unit in operation provides
only COOL and DRY modes, simultaneous operation is
possible.
