Settings and setting numbers
NOTE)
1. The
inside the frame indicates the second code no.
set when shipped from factory.
2. The settings are applied to the entire group, but if the mode
no. inside the parentheses is selected, the settings can be
applied to individual indoor units.
However, it is only possible to check any changes made to
the settings inside the parentheses in individual mode. (For
group batch operation, the changes are made but the dis-
play remains as it was when shipped from the factory.)
3. Do not set anything not shown above. If the applicable func-
tions are not available, they will not be displayed.
4. When returning to normal mode, the remote controller is ini-
tialized, so the display might show “88.”

operation setting” is changed, explain set contents to the
customer.
6. See below for details on the settings for cold areas.

Defrost operation
•
In heating operation, freezing of the outdoor unit’s coil
increases.
Heating capability decreases and the system goes into
defrost operation.
•
The remote controller will read “
” until the hot air starts
blowing.
•
It returns to the heating operation again after 6 to 8 minutes
(10 at the longest).
•
During defrost operation, the fans of the unit continues driv-
ing (factory setting).
The purpose of this is to maintain the amount of ventilation
and humidifying.
•
The change of air discharge grill’s location should be exam-
ined when the cold draft from air discharge grill is feared.
•
Though the fan can be stopped by the setting of remote
controller.
Do not stop the fan in the place where no ventilation by stop-
ping the fan may cause the influence of diffusion of air which
it is dirty and moisture into another room, or the inflow from
outside the room.
(outflow such as viruses from the sickroom, or smell leakage
from the rest room, etc.)
7. See below for details on the external input terminal function.
