DESCRIPTION
The Expert nano model 200NANO4CK13/14 is an electronic
regulator operating with microprocessor designed to control
refrigerated counters, display windows and static or ventilated
refrigeration units with off-cycle, electrical or hot gas defrosting
also in real time clock (RTC). It is fitted with three analogue inputs
for NTC temperature probes one of which configurable as digital
input, another digital input, four relays for the control of the
compressor, fans, light and defrosting evaporator and buzzer.
Two relays can be set as: alarm relay, simultaneously to the
compressor output, room light, cold function for pump down
operation, second defrosting relay, night relay or hot relay. The
regulator can be also configured for heat applications.
PRINCIPAL CHARACTERISTICS
Can be configured for cold, hot or neutral zone applications.
Relay for compressor and evaporator fan management (2 non
configurable relays) and defrosting resistances 1 and 2, alarm,
pump down start, room light and compressor output (2
configurable relays).
Clock for programmed defrosts (RTC), up to 6 starts in 24h.
Defrosting can be configured for off-cycle, heating element, cycle
inversion and cycle inversion with basin and frequency and
duration can be set. End-of- defrosting can be based on time or
temperature.
Key operated manual START/STOP defrosting.
Key operated ON/OFF.
Night / day management (energy saving).
Smart defrost functionality (energy saving).
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.
Power supply 12Vac.
HACCP function for memorization and visualization of the last
temperature alarm.
200NANO4CK14 Model with Connector for temperature repeater
ECHO.

MEANING
COLD FUNCTION ICON (icon activated with mOd=0)
Led OFF = Cold function OFF
Led ON = Cold function ON
Flashing Led = Cold function ON waiting for C1 delay
HOT FUNCTION ICON
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)
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 dO3=1 or dO4=3)
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).
Flashing Led = Alarm present

KEY FUNCTIONS
Key
FUNCTION
UP KEY
Increases values / Scrolls parameters in ascending
order / Deactivates acoustic alarm if present /
Acknowledges an alarm. With variable dO3=4 or
dO4=4 if pressed for over 3 sec, activates/deactivates
room light (DO3 or DO4 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

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.
