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 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 "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.
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
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 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 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.
