diagnostics

The electronic control on the machine continuously monitors its
operation. In the event of a malfunction, it activates a relay whose
contact generates a coded alarm signal sending ON/OFF signals
to the remote control and switching on the alarm LED
pre-set sequences. Some alarm conditions are automatically reset,
others require the intervention of the operator to search for the fault,
remove its cause and switch the unit back ON.
Example:
Alarm code 31 with persistent alarm condition
1 + 1 + 1=3 1
LED on for 1 second
LED off for 1 second
To restart the unit, remove the alarm cause and press the ON/OFF button.

ECO control
By pressing the ECO button, the green Eco
LED  will come on and the outdoor unit
will change its reference value for the desired
temperature from the normal condition to the
energy-saving condition during cooling or
heating operation.
When the ECO button is pressed again, the
green LED  will go off and the outdoor unit
will return its reference value for the desired
temperature to the normal condition.
In the event of a temporary power supply failure
the remote control will memorise the mode
settings at the time of failure.
Alarm codification
The alarm code generated by a failure is shown to the operator.
The alarm codification is based on the binary two-digit code X1 and
X2, as follows:
the first figure X1 flashes at 1 second intervals until it reaches the
number corresponding to the first digit, after a pause of 2 seconds,
second figure X2 starts to flash, again with 1 second intervals until
the number corresponding to the second is reached (only for two-
digit codes).
