you have to moderate the clamping torque, in order not to damage the box and screw
brackets.

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
Unless the evaporator temperature is below the defrost end tem-
perature you have set with the parameter d2, the defrost will
not be activated.
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.

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
• the kind of evapora-
tor probe you have
connected is not
right
• the evaporator
probe plays up
• the connection in-
strument-evaporator
probe is wrong
• the evaporator tem-
perature 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
instrument
• look at the param-
eter /0
• 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)
• look at the param-
eter /0
• 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
• all outputs will be
forced OFF
• the compressor will
work in accordance
with the parameters
C5 and C6
• if the defrost is run-
ning, it will immedi-
ately end
• the defrost will
never be activated
• if the parameter F7
has value 3 or 4, the
evaporator fan will
work in accordance
with the compres-
sor, except what
you have set with
the parameters F4
and F5
• the defrost will end
by time (parameter
d3)

0 = absolute evaporator fan stop temperature, 1 = evaporator fan stop temperature relative
to the cabinet temperature) (11)
F7 0 4 --- 4 evaporator fan action during the normal operation (0 = it will be forced OFF, 1 = it will be
forced ON, 2 = it will work in accordance with the compressor, 3 = it will work in accordance
with F1 and F2, 4 = if the compressor is ON, it will work in accordance with F1 and F2, if the
compressor is OFF, it will be forced OFF)

(4) the unit of measure depends on the parameter /8
(5) once you have modified the value of the parameter, you will have to switch off the power supply of the instrument
(6) if the parameter has value 0, the defrost will end by time (parameter d3); if the parameter F7 has value 3 or 4, the evaporator fan will work in accordance with the compressor,
except what you have set with the parameters F4 and F5
(7) unless the evaporator temperature is below the defrost end temperature you have set with the parameter d2, the defrost will not be activated
(8) if at the moment of the defrost activation the cabinet temperature is below the value “working setpoint + r0” , the instrument will not show temperatures above that value; if
at the moment of the defrost activation the cabinet temperature is above the value “working setpoint + r0” , the instrument will not show the increases of the temperature (if
the increase takes place below the value “working setpoint + r0” , look at the previous case); the instrument restores the normal operation once the after dripping evaporator
fan delay ends and the cabinet temperature falls below the freeze temperature
(9) if at the moment of the defrost activation the compressor is ON since a time lower than the one you have set with the parameter, the compressor will be forced ON for a
time such as to finish the time you have set with the parameter
(10) if the temperature alarm does not disappear at the end of the time you have set with the parameter A3, it will further be excluded for the time you have set with the parameter
A6; if the temperature alarm takes place during the defrost and does not disappear at the end of the time you have set with the parameter A7, it will further be excluded for the
time you have set with the parameter A6
(11) the evaporator fan stop temperature is “cabinet temperature - F1” ; you always have to consider the parameter F1 with positive sign.
