GENERAL INFORMATION
DESCRIPTION:
NECTOR is a control panel for refrigerated cells with a single-phase compressor up to
2HP that integrates the Datalogger function and various connectivity functions. It complies
with Regulation (EC) 37/2005 and with the relative standard EN 12830, with Directives
89/108/EEC, 92/2/EEC and with Italian Legislative Decrees no. 110 of 27/01/92 and no.
493 of 25/09/95, which impose the recording of temperatures of frozen foods and keeping
of the relevant data for at least one year.
NECTOR allows the complete management of all the components present on a
refrigeration system and stores the main quantities (status of the probes and digital inputs)
allowing the rapid daily analysis of data through smartphone apps or more in-depth
analysis through the TeleNET program with which to very simply organise, consult and
print graphics.

condensing unit consent in combination with Datalogger/remote control function.
KEY FEATURES:
-Direct compressor management, defrosting resistors, evaporator fans, cell light.
-Datalogger function with recording up to 2 years of ambient temperature and related
alarms. Instrument designation: EN 12830, S, A, 1, measuring range: -45T+99°C.
-Humidification function with dedicated 4-20mA humidity probe.
-Condenser fan speed management with 0-10V analogue output and dedicated pressure
probe.
-Evaporator fan speed management with configurable 0-10V analogue output.
-Defrost management at standstill, with resistance, hot gas or thermostatically controlled
resistance.
-Possibility to perform defrosting in real time clock.
-Direct management of the hot gas defrosting solenoid.
-Double evaporator management with double defrost end probe.
-Emergency operation (in case of faulty ambient probe).

INSTALLER WARNINGS
-Install the appliance in places that respect the degree of protection and keep the box as
intact as possible when drilling for the housing of the cable glands and/or pipe glands.
-Avoid using multi-pole cables in which conductors connected to inductive and power
loads and signal conductors are present, such as probes and digital inputs.
-Avoid housing power cables with signal cables (probes and digital inputs) in the same
ducts.
-Reduce the lengths of the connection cables as much as possible, avoiding that the
wiring takes on the shape of a spiral capable of possible inductive effects on the
electronics.
-All conductors used in the wiring must be suitably proportionate to support the load they
must supply.
-If it is necessary to move the probes farther, it is obligatory to use conductors of
appropriate cross-section and in any case not less than 1 mm2. Extending or shortening
of the probes could alter the factory calibration; then proceed with verification and
calibration by means of direct comparison with a thermometer that is ACCREDIA tested
and certified.
PACK CONTENTS
The NECTOR electronic controller, for assembly and use, is equipped with:
•No. 3 Seals, to be interposed between the fixing screw and the bottom of the box.
•No. 1 User manual.
•No. 1 NTC 10K 1% black 1.5m probe.
•No. 1 NTC 10K 1% black 3m probe.
•No. 1 NTC 10K 1% yellow probe of 3m length.
•No. 1 Calibration report.

PANEL INSTALLATION
Fig. 1: Press the buttons on the side doors to
release them from the locked position.
Fig. 2: Lift the two side doors and loosen the
four screws that secure the front to the
base.
Fig. 3: Open the front of the box by lifting it and
sliding the two hinges to the end of the
stroke. Bend the hinges and rotate the
front 180° downwards to access the
inside of the panel. Pay attention to the
battery cable and, if present, disconnect
it.

Fig. 4: Using the three pre-existing holes fix the
bottom of the box with three screws of
adequate length in relation to the
thickness of the wall on which to fix the
frame. Place a rubber washer (supplied)
between each fixing screw and the
bottom of the case.
Make all electrical connections according to the annexes diagrams for the
corresponding model (see the related tables in THE ANNEXES). To make
the electrical connections reliably and to maintain the degree of protection
of the box, it is advisable to use an appropriate cable press and/or pipe
press to tighten all the wiring harnesses. It is advisable to distribute the
passage of the conductors within the panel as neatly as possible, in
particular to keep the power conductors away from the signal conductors.
If necessary, use sealing straps
Fig. 5: Close the front by turning it 180° making
sure that all the cables are inside the
box, reconnect the battery (if present)
and tighten the 4 fixing screws. Connect
the supply voltage to the panel and
carefully read/program all the set
parameters.
On all loads connected to the NECTOR electronic controller, install
overcurrent protection devices for short circuits, in order to avoid damage
to the device. Every intervention and/or maintenance operation must be
carried out by disconnecting the panel from the power supply and from all
possible inductive and power loads to which it is connected; this is to
ensure the maximum safety condition for the operator.

GENERAL INFORMATION
For reasons of safety and greater practicality for the operator, the NECTOR system
provides three levels of parameter programming; the first for the configuration of
parameters that can be frequently modified by the user, the second reserved for the
installer for programming of the parameters relating to the various operating modes and
the third reserved for the installer dedicated to the configuration of the system.
If first level programming is being performed, it is not possible to directly access the
second or third level but instead it is necessary to exit the programming menu beforehand.
SYMBOLS
For convenience we will indicate with the symbols:
• () the UP key that performs the value increase and mute alarm functions;
• () the DOWN key that performs the value decrease and defrost forcing functions.
SET-UP AND DISPLAY SETPOINT
1. Press the SET key to display the current SET-POINT value (temperature).
2. Holding DOWN THE SET key and pressing one of the () or () keys changes the
SETPOINT value.
3. Release the SET key to return to the cell temperature display; the changes made will
be automatically saved.

1st LEVEL OF PROGRAMMING (User level)
To access the first level configuration menu you must:
1. Press and hold the () and () keys simultaneously for a few seconds until the first
programming variable appears on the display.
2. Release the () and () keys.
3. Select with the () key or the () key the variable to be modified.
4. After selecting the desired variable you will be able to:
•Display the setting by pressing the SET key.
•Change the setting by holding down the SET key and pressing one of the () or ()
keys.
5. Once the configuration values have been set, to leave the menu, press and hold the
() and () keys for a few seconds until the cell temperature value reappears.
Changes made to the variables will be automatically saved when leaving the configuration
menu.
