These are not set at the time of shipping from the factory.
These must be set after installation if automatic address setting is not 
performed.

Indoor unit address

Group address

Cooling intake temperature 
shift

Shifts the intake temperature during cooling and dry operation.
(Enabled only when the body thermostat is used.) 
Increase this value when it is diffi cult to turn the thermostat ON.

Automatic stop time after 
operation start

The time at which an indoor unit is automatically stopped after operation starts 
can be set in increments of 5 minutes.

Temperature shift for 
cooling/heating change in 
“auto heat/cool” mode

“Auto heat/cool” selects the operating mode automatically based on the 
difference between the room temperature and the temperature set on the 
remote controller. This setting establishes a shift temperature for the heating/
cooling temperature setting relative to the remote controller temperature 
setting.

Cooling

This setting changes the temperature range (upper limit and lower 
limit) which is set from the remote controller or central control device. 
The set upper limit must be greater than or equal to the lower limit. 
If the temperature setting is to be a single point, set the upper limit 
and lower limit to the same temperature.

Humidifier operation which ignores 
the heat exchanger temperature

During heating operation, the humidifier operates when the heat 
exchanger temperature is suitable for humidifying. This setting is 
used to ignore this condition for humidifier operation and operate the 
humidifier more.

Filter input switching

This setting switches the filter input according to the purpose of use.

Indoor unit electronic control valve

This setting indicates whether or not an indoor unit electronic control 
valve is present.
At the time of shipping, this setting is set according to the conditions 
of the indoor unit.

T10 terminal input switching

Ordinarily, the T10 terminal is used as the HA terminal at the time of 
shipping. However, this setting is used when the T10 terminal is used 
for OFF reminder or for fire prevention input.

Ventilation fan operation from 
remote controller

It is possible to install a total heat exchanger and ventilation fan in 
the system, which can be started and stopped by the wired remote 
controller. The ventilation fan can operate linked with the start and 
stop of the indoor unit, or can be operated even when the indoor 

unit is stopped.

Use a ventilation fan that can accept the no-voltage A contact as 
the external input signal.
In the case of group control, the fans are operated together. They 
cannot be operated individually.

Switching to remote controller
sensor

This setting is used to switch from the body sensor to the remote 
controller sensor.
Check that “remote controller sensor” is displayed.
Do not use this setting with models that do not include a remote 
controller sensor.
Do not use this setting if both the body sensor and remote sensor 
are used.

ON/OFF of “Operation change 
control in progress” display

In a MULTI system with multiple remote controllers, switching 
between heating and cooling is restricted, and “Operation change 
control in progress” is displayed.
This setting is used to prevent this display from appearing.
Refer to the item concerned with operating mode priorities.

Auto restart setting

When indoor unit is shutdown due to power failure, auto restart 
setting can restore the previous operating system.

Heat exchanger temperature for 
cold air discharge

The heat exchanger temperature control point for prevention of cold air 
discharge during heating operation can be changed.

Fan output switching

The indoor unit PCB optional output for the fan can be switched 
according to the purpose of use.

Drain pump delayed start time

The drain pump starts after the set time delay after cooling operation 
stops.

Humidifi er drain pump setting

This specifi es the humidifi er and drain pump setting.

DC fl ap operation mode

Changes fl ap operation to draft reduction mode.

DC fl ap swing mode

Selects the swing operation mode for the fl ap.

DC fan tap setting

Sets the DC fan tap according to the purpose of use.
Change the settings data at the same time.

Humidifi er ON time

Sets the humidifi er output ON time for when the humidifi er is operating.
ON/OFF control is performed during humidifi er operation.
This setting therefore sets the ON time per 60-second interval.

Timer function change prohibit

This function prohibits changes from being made to the remote 
controller time setting.

Smudging control

Smudging control is disabled when 0000 is set.
