screw brackets (on the right-hand side, by request); if you are using screw brackets, you have
to moderate the clamping torque, in order not to damage the box and screw brackets.
1.2 Electrical connection
The probe is connected with an high voltage terminal; in order not to get a shock, you
have to use probes with double insulation.
2 OPERATION
2.1 Preliminary information
During the normal operation the instrument shows the cabinet
temperature.
2.2 How to activate the defrost by hand
If you have to activate the defrost by hand:
• press for 4 s
3 WORKING SETPOINT
3.1 How to set the working setpoint
If you have to modify the working setpoint value:
• press and or (3)
(3) you can set the working setpoint between the limits you have set with the param-
eters r1 and r2.
4 CONFIGURATION PARAMETERS
4.1 How to set the configuration parameters
If you have to gain access the procedure:
• press and for 4 s : the instrument
will show

LED MEANING
Compressor LED
if it is lighted, the compressor will be ON
if it flashes, the defrost will be running
• press and or for setting “ -19 “
• press and for 4 s : the instrument
will show
If you have to select a parameter:
• press or
If you have to modify the value of the parameter:
• press and or
If you have to quit the procedure:
• press and for 4 s or do not op-
erate for about 60 s.

CODE
corrupted
memory
data
cabinet
probe
alarm
REASONS
there is the corruption
of the configuration
data of the memory of
the instrument
• the kind of cabinet
probe you have con-
nected is not right
• the cabinet probe
plays up
• the connection in-
strument-cabinet
probe is wrong
• the cabinet tempera-
ture is outside the
limits allowed by the
working range of
the instrument
REMEDIES
switch off the power
supply of the instru-
ment: unless the alarm
disappears, you will
have to change the in-
strument
• test the integrity of
the probe
• test the instrument-
probe connection
• test the temperature
close to the probe (it
has to be between
the limits allowed by
the working range)
EFFECTS
• you can not gain
access the setting
procedures
• the compressor will
be forced OFF
• the compressor will
be forced OFF
• if the defrost is run-
ning, it will immedi-
ately end
• the defrost will
never be activated
The instrument shows the indications above flashing.

d3 1 99 min/s (4) 30 defrost length
d4 0 1 --- 0 defrost activation every time you turn the instrument ON (1 = YES)
d5 0 99 min/s (4) 0 delay between you turn the instrument ON and the defrost activation (it is important if
d4 = 1)
d6 0 1 --- 1 freeze of the temperature showed by the instrument during the defrost (1 = YES) (5)
