・
Within a refrigerant system, indoor units are assigned addresses in the order they are recognized by the outdoor unit. Therefore, they are not necessarily assigned addresses in
order from the nearest to the outdoor unit first as depicted in drawings above.
・
Make sure that power has been turned on to all indoor units.
・
When addresses are set, you can have the registered indoor unit address No. and the outdoor unit address No. displayed on the remote control unit by pressing its CHECK button.
・
Automatic address setting can be used for an installation in which prulal indoor units are controlled from one remote control unit.
・
Once they are registered, addresses are stored in microcomputers, even if power is turned off.
・
If you want to change an address after automatic address setting, you can change it from the remote control unit with its “Address Change” function or by means of manual
setting. Set a unique address by avoiding the address assigned to other indoor unit on the network when the address is changed.
・
Do not turn on power to centralized control equipment until automatic address setting is completed.
・
When addresses are set, be sure to perform a test run and ensure that you can operate all indoor and outdoor units normally. Also check the addresses assigned to the indoor units.

“Address Change” is used,
when you want to change an indoor unit address assigned with the “Automatic Address Setting” function from a remote control unit
.
Accordingly, the conditions that permit an address change from a remote control unit are as follows.
If “CHANGE ADD.
▼
” is selected with some addresses falling outside these conditions, the following indication will appear for 3 seconds on the
remote control ”INVALID OPER” .
Automatic address setting for multiple refrigerant systems installation
Automatic address setting forsingle refrigerant system installation
When the eco touch remote control is connected, refer to the installation setting in the installation manual which is packed along with the remote control.
