(2) Setting the indoor unit address manually
The following is the method for the case where the indoor/outdoor control wire spans several outdoor units,
but the power to each system cannot be separately turned on or units operated separately.
* Manual addressing requires a wired remote controller. A wireless remote controller is not supported.
Set the system address of the outdoor units on the smallest outdoor address unit of the
fi
rst system (“1” at the time
of shipment). Set the system address of the smallest outdoor address unit of each system in order from 1 to 2.
Set the addresses of the outdoor units. Set addresses of the outdoor units from 1 to 2.
Set the indoor unit you want to set and remote controller on a one-to-one basis.
For group control, temporarily connect the indoor unit you want to set and the remote controller on a one-to-one
basis. (Disconnect the group bus wiring.)
Turn on the power of the smallest outdoor address unit and indoor unit.
* Initial communication is performed between the indoor and outdoor units for approximately 3 minutes after the
power is turned on, so do not perform operations such as changing the settings of the outdoor unit during that
time.
Carry out the following operations from the remote controller.
