If you are installing two indoor units in the same room and you
want them to operate in independent mode, it is necessary to
assign each unit its own address so that each unit can operate via
its own remote control.
For configuration, proceed as follows:
Configuration (of the unit)
• Press the and buttons of the infrared remote control and
hold them pressed for more than 5 seconds.
• The display will be cleared, the time segments will display the
first configuration item (rAdr = remote address) and the
temperature segments will display the default value of this
configuration item (Ab = control of both indoor units).
• Press either the
or button to change the default value (Ab)
to the new value (A) or (b).
• Press
button repeatedly until “UAdr” is displayed.
• Press either the
or button to change the default value of
CCN unit address (1) to the new value (1÷240).
• Press

Configuration (of the remote controller)
• Press the and buttons of the infrared remote control and
hold them pressed for more than 5 seconds.

display the first configuration item (CH = remote address) and
the time segments will display the default value of this
configuration item (Ab = control of both indoor units).
• Press either the
or button to change the default value (Ab)
to the new value (A) or (b).
• Press
button repeatedly until “tU” is displayed.
• Press either the

• Press
button repeatedly until “Cr” is displayed.
• Press either the

Fault code
The inside unit can detect any system fault and stop it at once.
The failure is recoverable based on the table VI below.
When a diagnostic is active, the green LED (P) and the yellow
LED (R) blink 0.5 seconds on, 0.5 seconds off and indicate a fault
code.
The yellow LED (R) indicates the tens digits.
The green LED (P) indicates the unit digits.
