System test
Indoor unit fault codes
The indoor unit can detect any system fault and stop it
at once. The failure is recoverable based on the table
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 fre-
quency.
• 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.

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.
This configuration procedure is not mandatory but may be necessary depending on installation requirements.
For display and remote control button reference see the remote control manual.
