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 inter-unit wires from the remote controller
terminal blocks (A/B) of the indoor unit connected

terminal blocks (A/B) of the other indoor unit.
(Non-polarity)
For address setup, refer to the Installation Manual
attached to the outdoor unit.

■
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.
