Diagnostic
Indoor unit
The indoor unit can detect any system fault and stop it immediately. The failure is recoverable based on the
table below.
When a diagnostic is active, the green LED (1) and the orange LED (3) blink 0.5 seconds on, 0.5 seconds off
and indicate a fault code.
The orange LED indicates the tens digits.
The green LED indicates the unit digits.
Two seconds elapse between the orange LED and the green LED lighting.
The sequence ends with both LEDs off for 4 seconds.
Example:
Fault code 13
• The orange LED blinks (it indicates the tens digits).
• Both LEDS are off for 2 seconds.
• The green LED blinks three times with a 0,5 seconds frequency.
• Both LEDS are off for 4 seconds.
If the fault code is lower than 13, the orange LED is not blinking.
The fault sequence described above is repeated until the fault has been repaired.
