.
• For the SET DATA of procedure
4
, select a SET DATA of the external static pressure to be set up from the
following table.
<Change on wired remote controller>
With a remote controller-less system (group control)
Besides the switching method using the wired remote controller as a way to establish the external static pressure
switching is also possible by changing over the jumper block settings on the indoor P.C. board as shown in the
following table.
* However, once these settings are changed, it is necessary to reset the SET DATA to 0001 that placing the
jumper block back to the factory default position and rewriting the SET DATA back to 0001 with wired remote
controller (sold separately).
• Change over the jumper blocks on the indoor P.C. board, and select the desired setting.

To secure better effect of
heating
When it is difficult to obtain satisfactory heating due to
installation place of the indoor unit or structure of the
room, the detection temperature of heating can be
raised. Also use a circulator or other machinery to
circulate heat air near the ceiling.

Remote control sensor
The temperature sensor of the indoor unit senses room
temperature usually. Set the remote control sensor to
sense the temperature around the remote control.

When
flashes, the remote control sensor is
defective.
Select the SET DATA [0000] (not used) or replace the
remote control.
Group control
In a group control, a remote control can control up to
maximum 8 units.
• The wired remote control only can control a group
control. The wireless remote control is unavailable
for this control.
• For wiring procedure and wires of the individual line
(Identical refrigerant line) system, refer to “Electrical
connection” in this Manual.
• Wiring between indoor units in a group is performed
in the following procedure.
• Connect the indoor units by connecting the remote
control wires from the remote control terminal blocks
(A, B) of the indoor unit connected with a remote
control to the remote control terminal blocks (A, B) of
the other indoor unit. (Non-polarity)
• For address setup, refer to the Installation Manual
attached to the outdoor unit.
