1-2. Features and functions

1

10 °C HEAT OPERATION
(MINIMUM HEAT OPERATION)

To avoid too much decrease of temperature in the room, it is
operated to prevent the room temperature dropping below
10 °C. When normal operation starts, the 10 °C heat opera­tion stops.

1

ECONOMY OPERATION

Operation of the indoor units in economy mode, which saves a
little power, reduces energy use more than normal operation.
If the room is not cooled (or heated) well during economy op­eration, select normal operation.

1

10 °C HEAT (ALL) OPERATION
(MINIMUM HEAT (ALL) OPERATION)

While this function is selected, all indoor units start the 10 °C
heat operation when all the indoor units are stopped by opera­tion of the [On/Off button] on the Central remote controller.

1

ECONOMY (ALL) OPERATION

If all the indoor and outdoor units are changed to economy
mode, this can save more energy than setting of each indoor
unit individually.

11

OUTDOOR UNIT LOW NOISE OPERATION

The outdoor units are operated to reduce noise during the
preset hours, such as at night.

1

SCHEDULE TIMER OPERATION

Operating automatically in accordance with the preset weekly
schedule. Different schedule can be set for each indoor unit.

11

REMOTE CONTROLLER PROHIBIT

It prohibits operation of the standard remote controller (at­tached in the indoor unit). It can prevent operation of a remote
controller, such as the remote controller fixed to a wall, by
children or outsiders.

IMPORTANCE

You can use both central remote controller and wireless re­mote controller simultaneously. But function is limited.
