 DISPLAYS
CHAMBER TEMPERATURE
Displayed with the instrument on, during normal operation.
EVAPORATOR TEMPERATURE (with the evaporator sensor present)
Press the button for a few seconds, then press the
select "Pb2".
Press the button for the evaporator temperature to appear on the display.
Press once again or do not operate to return to the chamber temperature.
CONDENSER TEMPERATURE (with the condenser sensor present)
Press the button for a few seconds, then press the
select "Pb3".
Press the button for the condenser temperature to appear on the display.
Press once again or do not operate to return to the chamber temperature.
COMPRESSOR OPERATION TIMER (if present)
Press the button for a few seconds, then press the
select "CH".
Press the button for the compressor operation hours to appear on the
display. Press once again or do not operate to return to the chamber
temperature.
 SETTING THE DATE AND TIME
Press the button for a few seconds, then press the
select "rtc".
Press the button for the following to appear on the display in sequence:
"yy", "nn", "dd", "hh" and "nn" followed by 2 numbers that correspond
respectively to the year, month, day, hour and minutes; values that can be
adjusted by acting on the or

 SETTING THE SET POINT
Press the button: the compressor LED will fl ash.
Press the or button within 15 seconds.
Press the button or do not operate for the compressor LED to go off, after
which the instrument will exit from the procedure.

.
maximum temperature alarm (HACCP alarm)
SOLUTIONS
Verify the chamber temperature
AH
See the A4 and A5 parameters
CONSEQUENCES
Alarm saved
Alarm output activated with u1=3
micro port input alarm (HACCP alarm)
SOLUTIONS
Verify what caused the input activation
See the i0, i1 and i4 parameters
id
CONSEQUENCES
Effect like the i0 parameter
Alarm saved with i4=1
Alarm output saved with u1=3
power failure alarm
SOLUTIONS
Verify what caused the power failure
See the AA parameter
PF
Press a button to restore the normal display
CONSEQUENCES
Alarm saved with interruption time exceeding parameter AA
Alarm output activated with u1=3
multifunction input alarm
SOLUTIONS

Verify what caused the input activation
iA
See the i5 and i6 parameters
CONSEQUENCES
Effect established by the i5 parameter
Alarm output activated with u1=3

iSd
Switch the instrument off and on again or disconnect the
power supply
CONSEQUENCES
The regulators go off
Alarm output activated with u1=3
button to
overheating condenser alarm
SOLUTIONS
Verify the condenser temperature
COH
See the C6 parameter
CONSEQUENCES
Alarm output activated with u1=3
compressor blockage alarm
SOLUTIONS
Verify the condenser temperature
See the C7 parameter
button to
Switch the instrument off and on again: if the condenser
CSd
temperature is still > parameter C7 when it is switched on
again, disconnect the power supply and clean the condenser
CONSEQUENCES
The evaporator compressor and fan go off
Alarm output activated with u1=3
Once the cause that triggered the alarm is resolved, the instrument restores
normal operation, except for the following alarms that require:
• "PF" (power failure) - any button to be pressed;
• "iSd" (pressure switch) - the instrument to be switched off or the power supply
• "CSd" (blocked compressor) - the instrument to be switched off or the power
 ERRORS
CODE MEANING
chamber sensor error
SOLUTIONS
Verify the type of sensor
Verify the integrity of the sensor
Verify the instrument-sensor connection
Verify the chamber temperature
Pr1
CONSEQUENCES
Compressor on or off for 10 min
Defrosting will not be activated
Alarm output activated with u1=3
The door resistors go off with u1=4
Disabling the evaporator valve with u1=5
to be disconnected
supply to be disconnected
