Central control address

Set when using a central control device.
Used when setting the central control address manually from the 
remote controller.

Operating mode priority change

Note (1)

Enabled only in Mini VRF System heat-pump models.

With indoor units that are installed in combination with an outdoor unit model where either heating or cooling 
operation can be selected, the operating mode of the indoor unit that starts first takes priority. The first indoor unit 
to operate can select any operating mode. When any mode other than fan mode is selected, then the operating 
modes that cannot be selected are not displayed on all remote controllers that are subsequently operated. 
“Operation change control in progress” is displayed, indicating that there are restrictions on the operating 
modes that can be selected.

-  When there are multiple remote controllers in the same refrigerant system, it is possible to set one remote 

controller as the priority remote controller (the remote controller which is given priority for selecting the 
operating mode). (If 2 or more remote controllers are set as priority remote controllers, an alarm will occur at 
the remote controllers, and operation will not be possible.)

-  When the priority remote controller is set to the operating mode for control, then all other remote controllers can 

select only the permitted operating mode, regardless of whether the priority remote controller is operating or 
stopped.

-  When a controlled remote controller is operated, “Operation change control in progress” is displayed.

There are other methods to avoid control in which the mode selected first takes priority.

Methods of remotely controlling the operating mode

(1) Use the central functions of a central control device.

(2) Use a remote control relay PCB at the outdoor unit.

Fan speed setting when 
heating thermostat is OFF

Changes the fan speed setting when the heating thermostat is OFF.

Heating intake temperature 
shift

Shifts the intake temperature during heating.
Can be set when the body thermostat is used.

Electric heater installation

Set when cost distribution is performed using an AMY central control system 
or similar system, and when an optional electric heater is installed. 
(This is unrelated to control of the electric heater.)

Humidifying when heater 
thermostat is OFF

Normally humidifying does not occur when the thermostat is OFF during 
heating operation. However, this setting can be changed in order to increase 
the amount of humidifying.
Caution: In order to avoid water leakage and damage to the fan, do not use 
this setting unless a vaporizing humidifi er is used.

Permit/prohibit automatic 
heating/cooling

This setting can be used to prevent the automatic heating/cooling display on 
the remote control if the unit confi guration permits automatic heating/cooling 
operation.

Cooling-only

This setting allows a heat pump indoor unit to be operated as a cooling-only 
unit.

individual or group-control indoor unit to which the 
remote controller used for detailed settings is con-
nected.
When detailed settings mode is engaged, 
operation stops at the individual or group-control 
indoor unit where the remote controller used for 
detailed settings is connected. Simple settings 
items can also be set at this time.
