Group control
In a group control, a remote controller can control
up to maximum 8 or 16 units. (Depending on the
outdoor unit.)
For wiring procedure and wiring method of the
individual line (Identical refrigerant line) system, refer
to "Electric work" 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.

Test run
Before test run
Before turning on the circuit breaker, carry out the
following procedure.
1) By using insulation tester (500VM ), check that
resistance of 1M or more exists between the
terminal block L to N and the earth (grounding).
If resistance of less than 1M 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.
Requirements for turning thermostat OFF
Cooling operation
When the outdoor/suction air temperature is lower than or equal to 66.2°F (19°C).
When the outdoor/suction air temperature is lower than or equal to 37.4°F (3°C) above the set temperature.
Heating operation

.
When the outdoor/suction air temperature is lower than or equal to 14°F (-10°C).
When the outdoor/suction air temperature is higher than or equal to 59°F (15°C).
When the outdoor/suction air temperature is higher than or equal to 37.4°F (3°C) above the set temperature.

Execute a test run
■
Used
Use the remote controller to check operations. For the operation procedures, refer to the Owner's Manual
provided.
You can do forced operations by using the test mode function in the following procedure, under conditions that the
thermostat is off.
This test mode function will automatically stop after 60 minutes, to prevent continuous forced operation, and do
normal operation (operation according to set temperature).
* Thermostat off: When the temperature of the room reaches the set temperature, the compressor of the outdoor
unit stops, and operation switches from "Cool" or "Heat" to "Fan". The indoor unit is operating, but the outdoor
unit repeatedly turns on/off in response to the room temperature.
CAUTION
• This test mode function does forced operation that ignores the set temperature, so be aware of the room
temperature and be sure to do a stop / end operation when your work is fi nished.
• This test mode function puts a higher than normal load on the equipment, so only use it for inspections and to
check operations.
