Cooling
This setting changes the temperature range (upper limit and lower
Heating
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
Drying
and lower limit to the same temperature.
Auto
heat/cool
When indoor unit is shutdown due to power failure, auto restart
setting can restore the previous operating system.
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.
This setting switches the filter input according to the purpose of use.
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.
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.
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.
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.
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.
