In a group control, a remote controller can control up to
maximum 8 units.

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 hot water modules by connecting the
remote controller wires from the remote controller
terminal blocks (A, B) of the hot water module
connected with a remote controller to the remote
controller terminal blocks (A, B) of the other hot
water modules. (Non-polarity)

Test run

 Before test run
• Before turning on the power supply, carry out the
following procedure.
1) By using 500 V-megger, check that resistance
of 1 MΩ or more exists between the terminal
block L to N and the earth (grounding).
If resistance of less than 1 MΩ 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.
 Execute a test run
Operate the unit with the wired 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.
