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.

Group control
In a group control, a remote controller can control up to
maximum 8 or 16 units. (Depending on the outdoor
unit.)
• The wired remote controller only can control a group
control. The wireless remote controller is unavailable
for this control.
• For wiring procedure and wires of the individual line
(Identical refrigerant line) system, refer to "8 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
controller wires from the remote controller terminal
blocks (A, B) of the indoor unit connected with a
remote controller to the remote controller terminal
blocks (A, B) of the other indoor unit. (Non-polarity)
• For address setup, refer to the Installation Manual
attached to the outdoor unit.

Test run
Before test run
• Before turning on the circuit breaker, carry out the
following procedure.
1) By using insulation tester (500V Megger), check
4
.
that resistance of 1 MΩ or more exists between the
terminal block L to N and the earth (grounding).
If resistance of less than 1 MΩ is detected, do not
run the unit.
2) Check the valve of the outdoor unit being opened
fully.
• To protect the compressor at activation time, leave
power-ON for 12 hours or more for operating.
• Before starting a test run, be sure to set addresses
following the Installation Manual supplied with the
outdoor unit.
Execute a test run
• When a fan operation is to be performed for an
individual indoor unit, turn off the power, short circuit
CN72 on the circuit board, and then turn the power
back on. (Set the operation mode to "fan" to operate
the unit.) When the test run has been performed using
this method, be sure to release the short circuit of
CN72 after the test run is completed.
Operate the unit with the remote controller as usual.
For the procedure of the operation, refer to the Owner's
Manual attached to the outdoor unit.
A forced test run can be executed in the following
procedure even if the operation stops by thermostat-
OFF.
In order to prevent a serial operation, the forced test run
is released after 60 minutes have passed and returns to
the usual operation.
CAUTION
CAUTION
• Do not use the forced test run for cases other than the
test run because it applies an excessive load to the
devices.
Wired remote controller
Be sure to stop the air conditioner before making
settings.
(Change the setup while the air conditioner is not working.)
