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 device 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 "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.
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 power supply, carry out the following procedure.
1) By using 500V-megger, check that resistance of 1MΩ or more exists between the terminal block L1 to L2
and the earth (grounding). If resistance of less than 1MΩ 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 before operating.
• Do not press the electromagnetic contactor to forcibly perform a test run. (This is very dangerous because the
protective device does not work.)
• Before starting a test run, set addresses by 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
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 finished.
• This test mode function puts a higher than normal load on the equipment, so only use it for inspections and to
check operations.
