- THERMOSTAT FUNCTION MODES (mOd)
The variable mOd allows the selection of function mode of the
thermostat, in particular:
- COLD MODE (mOd=0)
The DO1 output is activated when the temperature measured by
the ambient probe reaches or exceeds the SET POINT+r0 value
and remains active until the temperature drops below the SET
POINT. In this mode, the DO1 output is linked to the cold
function icon.
- HOT MODE (mOd=1)
0
The DO1 output is activated when the temperature measured by
the ambient probe reaches or exceeds the SET POINT-r0 value
and remains active until the temperature increases and exceeds
the SET POINT. In this mode, the DO1 output is linked to the hot
0.0
function icon; defrosting and fan stop FSt are DISABLED.
- PASSWORD FUNCTION
The password function is activated by entering a value other
than 0 for the PA parameter. See parameter P1 for various
protection levels. The protection is activated automatically if the
-45
keyboard remains inactive for about 30 seconds. The figure 000
appears on the display. Use the up/down keys to change the
99
number and the SET key to confirm. The password entry
template 000 disappears if the keyboard is not activated within
1
30 seconds. If you forget the password, use the universal
number 100.

- EMERGENCY MODE IN THE CASE OF ERROR EO
This safety mode guarantees the functioning of the compressor
even in the case of a faulty ambient probe (error EO). If probe
120
errors E0 and CE1 are different to 0, the compressor functions in
operation pause mode, with compressor ON for the time CE1
and OFF for the time CE2. If CE1>0 in the case of error E0,
defrosting is performed in normal functioning mode. If CE1=0 the
1
emergency mode in the presence of error E0 remains disabled.
The compressor remains off and defrosting is prevented to
conserve the remaining cold. Eliminate as soon as possible the
0
cause of error E0 and reactivate the control's normal function for
a correct temperature adjustment.
- MANUAL DEFROSTING ACTIVATION
6=14400 baud
5
To activate defrosting simply press the DOWN key for more than 30
7=19200 baud
seconds; this activates the heating elements relay. Defrosting is not
8=38400 baud
activated if the appropriate conditions are not present (end-of-
defrosting temperature (d21 or d22) set lower than the
temperature read by the evaporator probe). Defrosting terminates
when the end-of defrosting temperature (d21 or d22) is reached or
for a maximum defrosting time (d31 or d32) or by manually forced
3
end-of-defrosting (end-of-defrosting key or digital input).
- MANUALLY FORCED END OF CURRENT DEFROSTING
Pressing the DOWN key for 3 seconds during defrosting forces
the end of the current defrosting. In the case of manual end-of-
defrosting, dripping is also excluded.
- HOT GAS DEFROSTING
Set the parameter d1 = 1 or 2 for the management of inversion
defrost cycle. During the entire defrosting process the
compressor and defrost relays are activated. In this case, you
cannot set defrost in succession, dd2 is forced to 0. During
dripping (d7) the compressor stops and, if d1 = 2, the defrost
relays remain activated in order to ensure the ignition of the
resistances of the basins.
If d1 = 2 it may be necessary to add external electromechanical
components for proper control of the solenoid valves.
Expert nano LINE
For a correct control of the system, the installer must use the
0
defrost output which must allow the opening of the inversion
cycle electrovalve and closing of the liquid electrovalve. For
0...99
capillary systems (without thermostatic valve) it is sufficient to
1...12
control the inversion cycle electrovalve using the defrost relay
command.

- HEATER DEFROST BY TIME WITH TEMPERATURE CONTROL
0...23
Set the parameter d1 = 3 for the management of heater defrost
0...59
by time with temperature control. During the defrost the
outputs are activated when the evaporator's temperatures are
---
lower than d21 or d22. Defrost stops after d31 or d32 minutes. It
reading
allows energy saving and a better defrost process.

- AMBIENT TEMPERATURE DISPLAY DURING AND AFTER
DEFROSTING During defrosting and for a minute following the
end of defrosting, the display continues to display the last
ambient temperature value read before start of defrosting.
- RS-485 CONNECTION
Connection to a RS485 network must be chain type, avoiding
star connections and observing A and B polarity. It is advisable
to use BELDEN 8762 cables. The configuration of the device in
the TeleNET program is performed by entering the module
name such as "Expert Nano4CK device" and assigning to it the
same network address entered in the variable Ad. For a
Modbus-RTU network connection and for details on the
protocols of these devices, refer to the manual "MODBUS-
RTU_EXP_DIN_NANO4CK" which can be downloaded from our
internet site at www.pego.it.
- HACCP ALARM MANAGEMENT
With ambient probe temperature ≤ A1 , after the Ald time, the
EL low temperature alarm is activated.
With ambient probe temperature ≥ A2 , after the Ald time, the
EH high temperature alarm is activated.
During a high or low temperature alarm, the display alternates
the visualisation of the temperature with the EH or EL headings;
the alarm relay is activated (if set), the Buzzer (silenceable) and
the alarm bell icon (flashing).
When the set alarm conditions are turned off, alarm signals
automatically undo (the alarm relay is deactivated, the buzzer is
silenced and the normal visualisation is reactivated).
The alarm bell icon remains on (fix) to indicate that EH or EL
alarm was triggered and the memorisation of the event (see
HACCP menu for displaying the latest temperature alarm
activated). To get the alarm, push the arrow button up when the
fix bell light is on. Besides, the starting date of the latest EH or
EL event is registered, together with its duration and its
maximum or minimum reached temperature.
A counter of the nr of occurred alarms from the latest alarm
reset (max 99 alarms can be counted) is also present.
To display data related to the latest temperature alarm, enter in
the HACCP menu (push the arrow button up + stand-by for 3
seconds). Inside the menu, all the data can be scrolled with the
up and down arrows or they can be reset, by pressing the SET
button + arrow up button for 5 seconds.
Once the reset occurred, a BIP with the buzzer is provided to
confirm the occurred cancelation. To exit the menu, wait 10
seconds without pressing anything or press simultaneously the
up and down arrows.
HACCP variables are available in read-only mode and are the
following:
