Group control
■
(Outside Air Unit)
The Outside Air Unit and indoor unit for air
•
conditioner cannot be connected as a group control.
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
"9 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.

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
L1 to L2 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.
