Manuale d’uso e manutenzione / Use and maintenance manual
DESCRIPTION
The Expert nano model 200NANO3CF is an electronic regulator
operating with microprocessor designed to control refrigerated
counters, display windows and static or ventilated refrigeration
units with off-cycle or electrical defrosting. It is fitted with two
analogue inputs for NTC or PTC temperature probes, one digital
input, three relays for the control of the compressor, fans and
defrosting function (the defrosting relay can be configured as the
light command) and buzzer. The regulator can be also configured
for heat applications.
PRINCIPAL CHARACTERISTICS
Can be configured for hot or cold applications.
Can be configured to read NTC or PTC probes.
Relay for controlling the compressor, evaporator fans and
defrosting elements (defrost output can be configured like light
output).
Defrosting can be configured for off-cycle, heating element, heating
element with temperature control or cycle inversion and frequency
and duration can be set. End-of- defrosting can be based on time or
temperature.
Configurable input as evaporator probe or dirty condenser alarm
probe.
Key operated manual START/STOP defrosting.
Key operated ON/OFF.
Cold room light ON/OFF switch with key or by means of door
switch (if defrost output is configured like cold room light).
Display/adjustment of temperature with decimal point.
Flat front surface for easy cleaning and keys of ample dimensions
which can be customised with various colours (on request).
3-Digit LED display with sign, decimal point and system status icon.
Internal buzzer for acoustic signals.
PEGO programming philosophy guaranteeing immediate start-up.
RS485 serial connection with Modbus-RTU or Telenet protocol.
IP65 front protection. Two-fold fastening option: clips / screws.
Voltage and terminal type depending on model

KEY FUNCTIONS
Key
FUNCTION
UP KEY
Increases values / Scrolls parameters in ascending
order / Deactivates acoustic alarm if present /
Acknowledges an alarm. With variable do2=1 if pressed
for over 3 sec, activates/deactivates room light (DO2
output). With manual activation/ deactivation of the
light a BIP is generated to confirm.
DOWN KEY
Decreases values / Scrolls parameters in descending
order / If pressed for over 3 sec. activates manual
defrosting (if suitable conditions are present).
Terminates defrosting if pressed for over 3 sec. during
the defrosting process. With manual activation/
deactivation of defrosting a BIP is generated to
confirm.
Stand
by
STAND-BY KEY
If pressed for over 1 sec. alternates the Stand-By with
normal mode and vice versa. When mode is alternated
a BIP is generated to confirm. In Stand-By mode the
system stops and the display signals OFF and the
temperature alternating.
SET KEY
Displays the set point.
Allows the set point to be entered when pressed in
combination with the DOWN or UP keys. Resets the
acoustic alarm if present.

MEANING
COLD FUNCTION ICON
(icon activated with mOd=0/2)
Led OFF = Cold function OFF
Led ON = Cold function ON
Flashing Led = Cold function ON waiting for C1 delay
HOT FUNCTION ICON
(icon activated with mOd=1/3)
Led OFF = Hot function OFF
Led ON = Hot function ON
FAN ICON
Led OFF = Fans OFF
Led ON = Fans ON
Flashing Led = Fans paused after defrosting (see
parameter F5)
DEFROSTING ICON
(icon activated with mOd=0/2)
Led OFF = Defrosting OFF
Led ON = Defrosting ON
Led Flashing = Dripping in progress after defrosting (see
parameter d7)
DOOR SWITCH / ROOM LIGHT ICON
Led OFF = Door switch not activated or not used and
room light off
Led ON = Room light ON (function active only if
variable dO2=1)
Flashing Led = Door switch activated or room light ON
with alarm E8.
ALARM ICON
Led OFF = No alarm present
Led ON = Indicates temperature alarm intervention
with remedy (HACCP alarm).

key, the SETPOINT value can be changed.
Release the SET key to return to view the room temperature;
the changes made will be automatically saved.
LEVEL 1 PROGRAMMING /
(

Press the UP and DOWN keys simultaneously for over 3 sec. to
access the Level 1 programming menu. When the menu is
accessed, a BIP is generated to confirm. The system leaves the
menu after 30 seconds.
LEVEL 2 PROGRAMMING
/ (
+
+Stand-by)
Press the UP, DOWN and STAND-BY keys simultaneously for
over 3 sec. to access the Level 1 programming menu. When the
menu is accessed, a BIP is generated to confirm and the system
is placed in Stand-By mode.
EXIT PROGRAMMING MENUS /
(
+
)
Pressing the UP and DOWN buttons simultaneously in any
programming menu for over 3 sec. causes the system to save
the settings entered and leave that menu. A BIP is generated to

ELECTRICAL PRESCRIPTIONS
Avoid using multipolar cables with conductors connected to inductive
and power loads and signal conductors such as probes and digital
inputs. Avoid installing in the same channels power cables and signal
cables (probes, digital inputs or RS485 connections). Reduce to a
minimum the length of the connecting cables, avoiding that the
cabling takes on a spiral form which may have inductive effects on the
electronic system. All conductors used in the cabling must be
appropriately sized in order to support the load which they must
provide. If it is necessary to extend the probes, use conductors with
appropriate cross-sections and not less than 1 mm². The extension or
reduction of the probes may alter the calibration which was
performed in the factory. Therefore, verify and calibrate by means of
an external thermometer.
