Operating test, address selector and fault code
Fault code
Once a failure occurs with the indoor unit in operation,
the green or orange LED flashes at intervals of 0.5 seconds.
The fault code is deduced from the number of times the green
LED or orange LED flashes, blocking unit operation.
Between one flash cycle and the next one, a pause of 3 seconds
elapses.
