16. Accessing “Pr2” and SECURITY CODE input
To access parameters in “
Pr2
” a security code is required.
1. Enter Function Menu, select label “
Pr2
” and press the “
SET
” key. The
“PAS” flashing message is displayed, shortly followed by “0 _ _” with a
flashing zero.
2. Use
“UP”
or
“DOWN”
to input the security code in the flashing digit;
3. Confirm the figure by pressing “
SET
”.
4. Repeat operations 2 and 3 for the other digits.
5. If the security code is correct the access to “
Pr2
” is enabled by pressing
“
SET
” on the last digit, otherwise the “rtC” menu is shown.
If no key is pressed for more than 15 seconds the instrument reverts to room
temperature display mode.
The default SECURITY CODE is
321 .
NOTA1:
the general security code is
981
. (please refer to parameter PAS)
NOTE2
: each parameter in “Pr2” can be removed or put into “Pr1” (user
level) by pressing
“SET
+
è
”
. In Pr2 when a parameter is present in “Pr1” or
“rtC” LED
is on.

REGULATION
HyIntervention differential for set point:

cycle
PFt Maximum acceptable duration of power failure:
(0
÷

failure duration is less than PFt, the cycle restarts from the same point at
which it was stopped otherwise the cycle restarts from the beginning of
the current phase.
iPd Temperature difference for the automatic recognition of the insert
probe:

insert probe and the thermostat probe is less than iPd, the selected cycle
is made by time.
iPtTime delay for the automatic recognition of the insert probe:

a cycle and the comparison of the temperature of the thermostat probe
and the insert probe to recognising if the insert probe is used.
Con Compressor ON time with faulty probe

which the compressor is active in case of faulty thermostat probe. With

which the compressor is off in case of faulty thermostat probe. With
COF=0 compressor is always active

DEFROST
tdF Defrost type (not present in the XB350C)
: (
rE
= electrical heater;
in
=
hot gas).
dPO Defrost before the holding: no
= no defrost;
YES
= defrost at the start
of a holding cycle.
IdF Interval between defrost cycles
: (0.1
÷
24.0; res. 10 min) Determines
the time interval between the beginning of two defrost cycles. (with 0.0
the defrost is disabled)
dtE Defrost termination temperature (not present in the XB350C)
: (-
50
÷
50 °C/°F) Sets the temperature measured by the evaporator probe,
which terminates the defrost.
MdF Maximum length for defrost

defrost) it sets the defrost duration, when EPP = YES (defrost
termination based on temperature) it sets the maximum length for
defrost.

temperature;

dEF:
“dEF” message
Fdt Drip time (not present in the XB350C)
: (0
÷

between reaching defrost termination temperature and the restoring of
the controllers' normal operation. This time allows the evaporator to
eliminate water drops that might have formed during defrost.
FANS
FnC Fans operating mode during the holding phase
:
C-n
= runs with the compressor, OFF during defrost;
o-n
= continuous
mode, OFF during defrost;
C-Y
= runs with the compressor, ON during
defrost;
o-Y
= continuous mode, ON during defrost;
FSt Fan stop temperature
: (-50÷50°C/°F; res. 1°C/1°F) if the temperature,
detected by the evaporator probe is above FSt fans are stopped. It
serves to avoid blowing warm air around the room.
AFH Differential for the stop temperature and for the alarm
(0.1
÷
25.0
°C; ris.0.1°C/1°F) Fans carry on working
when the temperature reaches
the FSt-AFH value, the temperature alarm recovers when the
temperature is AFH degrees below the alarm set.
Fnd Fan delay after defrost:
(0
÷
255 min) The time interval between end of
defrost and evaporator fans start.
ALARM
ALU MAXIMUM temperature alarm
: (1
÷
50 °C/°F) When the “SET+ALU”
temperature is reached the alarm is enabled, (possibly after the “Ald”
delay time).
