DESCRIPTION
The Expert nano model 200NANO3CK 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 also in real time clock
(RTC). It is fitted with two analogue inputs for NTC 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.
Relay for controlling the compressor, evaporator fans and
defrosting elements (defrost output can be configured like light
output).
Clock for programmed defrosts (RTC)
Defrosting can be configured for off-cycle, heating element or cycle
inversion 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.
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.
HACCP function for memorization and visualization of the last
temperature alarm

KEY FUNCTIONS
Key
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 KEY
If pressed for over 1 sec. alternates the Stand-By with
Stand
normal mode and vice versa. When mode is
alternated a BIP is generated to confirm. In Stand-By
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.
STATUS ICON
ICON
COLD FUNCTION ICON (icon activated with mOd=0)

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).
