Note for Multi System
A multi system has one outdoor unit connected to multiple indoor units.
Selecting the operation mode
1. When the priority room setting is active but
the set unit is not operating or when the priority
room setting is inactive
When more than one indoor unit is operating, priority is given to the first
unit that was turned on.
In this case, set the units that are turned on later to the same operation
mode as the first unit.
Otherwise, they will enter the standby state.
2.
With the priority room setting active
Refer to
“Priority room setting”
on the next page.
NIGHT QUIET mode (Available only for
COOL operation)
NIGHT QUIET mode requires initial programming during installation. Please consult your retailer or dealer for assistance.
NIGHT QUIET mode reduces the operation noise of the outdoor unit during the night-time hours to prevent annoyance to neighbours.
• NIGHT QUIET mode is activated when the temperature drops 6°C or more below the highest temperature recorded that day.
When the temperature difference between the current outdoor temperature and the maximum outdoor temperature becomes
less than 4°C, this function will be cancelled.
• NIGHT QUIET mode slightly reduces the cooling efficiency of the unit.
OUTDOOR UNIT QUIET operation
For details on OUTDOOR UNIT QUIET operation, refer to the operation manual included with the remote controller.
1.
When the priority room setting is active but the set unit is not operating or when the
priority room setting is inactive
When using the OUTDOOR UNIT QUIET operation feature with a multi system, set all indoor units to OUTDOOR UNIT QUIET
operation using their remote controllers.
When cancelling OUTDOOR UNIT QUIET operation, simply cancel the mode on one of the operating indoor units using their
remote controller.
However OUTDOOR UNIT QUIET operation will remain displayed on the remote controllers for the other rooms.
We recommend you cancel operation in all rooms using their remote controllers.
2.
With the priority room setting active
