Address selector
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 (unit address) Table I
• 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 tempera-
ture 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 to transmit the new configuration to the unit.
• Press
button to leave the configuration menu.
Configuration (remote control address) Table II
• Press the
and
buttons of the infrared remote control and
hold them pressed for more than 5 seconds.
• The display will be cleared, the temperature segments will
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 to set the new configuration on the remote
control.
• Press
button to leave the configuration menu.
Note:
When 30 seconds have elapsed and no buttons have been
pressed, the remote control will automatically exit the
configuration menu and the procedure has to be restarted.
Fault code for 40SMC---N
When a fault code is detected while the indoor unit is working,
the green LED of the unit starts to blink every 0.5 seconds.
The alarm code can be drawn by the number of times the LED
blinks and stops the unit.
5 seconds elapse between one series of blinks and the next.

Fault code for 40SQV
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 0.1 seconds on, 0.1 seconds off and indicate a
fault code.
The yellow LED (R) indicates the tens digits.
The green LED (P) indicates the unit digits.
Two seconds elapse between the yellow LED and the green
LED lighting.
The sequence ends with both LEDs off for 4 seconds.
Example:
Fault code 12
• The yellow LED blinks (it indicates the tens digits).
• Both LEDS are off for 2 seconds.
• The green LED blinks twice with a 0,5 seconds frequency.
• Both LEDS are off for 4 seconds.
The fault sequence described above is repeated until the fault
has been repaired.
If the fault code is lower than 10, the yellow LED (R) is not
blinking.

Guide for the owner
When installation and tests are completed explain the Operation
and Maintenance Manual to the owner, with particular attention to
the main operating modes of the air conditioner, such as:
• Turning the unit on and off.
• Functions of the remote control.
Leave the two installation manuals for the indoor and outdoor units
with the owner for future use during maintenance operations or for
any other needs.
