ALARMS
The air conditioner features a self-protection program that, in the event of anomalous situations, automatically shuts down unit opera-
tion and places it in pre-alarm status. In such a case, there are two resolution possibilities:
a)
If the pre-alarm persists for a time greater than the maximum programmed for the fault type, the unit goes to Alarm status.
b)
If the fault is no longer present, the pre-alarm status ceases and the unit can resume operation, in accordance with the safety
time required by the compressor.

ALARM DISPLAY

In the event that the air conditioner goes to Alarm status, the fault type will be automatically displayed by a special sequence of yellow
and red light flashes on the wall receiver LED.
The following alarm codes are possible:
❍ Yellow LED: flashes cyclically 5 times, then goes out for 5 seconds.
❒ Red LED: lights up when the yellow LED goes out, thus indicating a specific code.
