ADJUSTING THE THERMOSTAT TEMPERATURE
General information
The digital thermostat controls A FIG. 3 the activity of the compressor and the defrosting cycles (by forceably
stopping the compressor). It is powered with a voltage of 230 V.

the UP key for at least 4 seconds, the instrument requests a defrosting cycle; if an alarm is active, the
