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.

• When "RC" is selected,
lights up. However, it is
not displayed when it is set as a sub-remote control.
• When
flashes, the remote control sensor is
defective. Select the Set data "Body" or replace the
remote control.
Group control
In a group control, a remote control can control up to
maximum 8 or 16 units. (Depending on the outdoor
unit.)
• 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
"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
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.

Test run
Before test run
• Before turning on the circuit breaker, carry out the
following procedure.
1) By using insulation tester (500 VMΩ), check 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 control 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.
