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 probe is connected to a terminal of the mains voltage; use only NTC probes with double insulation.
When replacing the probe, use only original spare parts.
In normal conditions of use, the instrument displays the temperature detected by the cell probe: by pressing
the UP key for at least 4 seconds, the instrument requests a defrosting cycle; if an alarm is active, the
instrument displays the alarm code until its cause has been removed (see section Signals and Alarms)
The electronic thermostat installed in the machine delays the activation of the
refrigeration unit by 3 minutes from when the instrument is turned on.
Programming the working setpoint
Press the SET key to display the current working setpoint value: the "comp" led flashes rapidly. To modify
the value, keep the SET key pressed down and at the same time operate on the UP or DOWN keys (the
working setpoint is preset at 8°C and can vary within the preestablished limits min.4 max. 16°C); having
modified the value, the SET key must be the last to be released.
Signals and alarms
Signals:
The "comp" led is lit
The "comp" led is flashing
Alarms:
The display shows the message "E0"

OPERATION ON THE MACHINE

FIG. 3
Indicates that the output is activated
A defrosting cycle is in progress
Indicates one of the following faults: the type of cell probe is not
correct, the cell probe is defective, incorrect cell probe-instrument
connection, the temperature detected by the cell probe is outside
the admissable limits of the cell probe (the output is deactivated).
Indicates corruption of the configuration data: switch the
instrument off and on again; if the alarm does not disappear when
the machine is turned back on, it will be necessary to replace the
instrument (the output is deactivated).
