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.
2A
Filter input switching
This setting switches the filter input according to the purpose of use.
2C
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.
2E
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.
31
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.
32
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.
34
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.
See the item concerned with operating mode priorities.
35
OFF reminder function for weekly
timer
This setting switches the operation when the weekly timer is
connected to the remote controller.
This can be used to prevent cases in which the unit is accidentally
left ON. There is no change when this setting is ON, however it is
necessary to set the weekly timer ON time.
