For wiring procedure and wiring method 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
controller inter-unit 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.
Remote controller sensor
The temperature sensor of the indoor unit senses room
temperature usually. Set the remote controller sensor
to sense the temperature around the remote controller.

for this control.
By using insulation tester (500VM
Ω
), check that
resistance of 1M
Ω
or more exists between the
terminal block L to N and the earth (grounding).
If resistance of less than 1M
Ω
is detected, do not
run the unit.

Requirements for turning
thermostat OFF
Cooling operation
•
When the outdoor/suction air temperature is lower
than or equal to 19 °C.
•
When the outdoor/suction air temperature is lower
than or equal to 3 °C above the set temperature.
Heating operation
•
When the outdoor/suction air temperature is lower
than or equal to -10 °C
•
When the outdoor/suction air temperature is higher
than or equal to 15 °C.
•
When the outdoor/suction air temperature is higher
than or equal to 3 °C above the set temperature.
■
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
attached Owner’s Manual 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
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.)
