1. PRODUCT PRESENTATION
Introduction
This section contains general information on the NECS-ME
range of products. For detailed information refer to the specific
sections in this bulletin.
1.1 NECS-ME units
The NECS-ME chillers are a range of remote-condensation liq-
uid units running on R410A ecological gas.
They are indoor units with hermetic scroll compressors in a
single-circuit (2-compressor units) and twin-circuit (4-compres-
sor unit) tandem configuration, and braze-welded plate heat
exchangers.
1.2 R410A refrigerant
The use of R410A has improved the energy efficiency of the
units, in full respect of the environment (O.D.P.=0)
1.3 Combination with a remote condenser
Compact units designed for residential and commercial sys-
tems.
1.4 Integral control and adjustment
The evaporating unit is supplied complete with integral micro-
processor control and optional connection to a remote con-
denser.
1.5 Hydronic unit incorporated
The integrated hydronic unit comprises the main hydraulic
components; it is available in various configurations with single
or dual orthogonal pumps and high or low heads.
1.6 Silent running
The NECS-ME chillers stand out for their silent running. If
specifically requested, the casing of the unit can incorporate
a layer of soundproofing made from high intermediate density
conoid sandwich material which reduces noise sufficiently to
allow NECS-ME to be used in residential and commercial ar-
eas without having to install it in dedicated rooms (technical
rooms). The benefit in terms of noise reduction is 4dB(A) in the
models with 2 compressors and 10dB(A) in the models with 4
compressors.
1.7 Ease of installation
All the connections of the NECS-ME units are located on the
side in order to simplify installation operations. This feature
also makes it possible to save space as the units can be posi-
tioned near the perimeter walls without compromising access
to the internal components during maintenance.
1.8 Versatility
On request, the NECS-ME units can be fitted with an inte-
grated pump unit for circulating the liquid in the system, with
a high or low head depending on the various application re-
quirements. As well as the primary pump, it is also possible to
add an auxiliary circulation pump which starts automatically if
the former develops a fault. This makes it possible to respect
the harshest safety aspects of the system, whilst allowing the
pumps to be rotated to balance operating hours (thus prevent-
ing risks of mechanical breakage) and to manually select one
of the two pumps.
1.9 Usability
The electronic controller of the NECS-ME features a program-
mable menu containing the most popular European languages
which the user can choose depending on the country in which
the unit is used (available standard in the 4-compressor unit, in
the reduced mode in the 2-compressor version).

2.4 Controller
The controller is available in two formats:
- W3000 Base: keyboard and LED display.
- W3000SE Compact: the keypad features functional controls
and a complete LCD display that allows assessment and inter-
vention on the unit by means of a multi-level menu with selecta-
ble user’s language.
The diagnostics comprises a complete alarm management sys-
tem, including “black box” (via PC) functions and an alarm log
(via display or also PC) for optimised analysis of unit perform-
ance.
Compatibility with the remote keyboard managing up to 10
units.
The presence of the programmable timer allows the creation
of an operating profile containing up to 4 typical days and 10
time bands.
Common features: Heat adjustment is based on the exclusive
QuickMind algorithm, featuring a self-adaptive logic which is
useful for systems with a low water content. Alternatively, pro-
portional or proportional-integral adjustments can be set.
For systems featuring more than one unit, the resources can
be adjusted using optional propriety devices. Consumption and
performance accounting can also be implemented. Supervision
can be easily developed via proprietary devices or the integra-
tion in third party systems by means of the most common pro-
tocols as ModBus, Bacnet, Bacnet-over-IP, Echelon LonWorks
protocols.

2.6 Control unit with LCD display (standard)
The new “W3000 Base” control unit is installed on all NECS-ME
0152..0612 units.
The new “W3000SE Compact” control unit is installed on all
NECS-ME 0604..1604 units.
Main functions: QuickMind, local and remote FWS supervi-
sion, dual set point management, etc, confirm Climaveneta’s
commitment to continually developing its electronics technol-
ogy.
The heat pumps, moreover, are fitted with the original Cli-
maveneta defrostingcontrol systemcalled “Autotuning Defrost”
which considerably reduces defrosting times, thus improving
the energy performance of the unit. Interfaces with BMS sys-
tems: METASYS®, MODBUS®, LONWORKS®, SIEMENS®,
TREND®.
Black Box logs data relative to 200 alarm events which can be
printed with a personal computer.
QuickMind is a special control unit which monitors the main
operating parameters, predicts system behaviour and antici-
pates unit settings in order to constantly optimise performance;
it allows both return and delivery water temperatures to be
chosen as adjustment parameters. It can reduce outlet tem-
perature fluctuations even with a small amount of water in
the system. When, for dual-compressor chillers featuring a
maximum of 12 start-ups per hour and using a traditional ad-
justment system, the minimum recommended water content
is 5.5 l/kW. QuickMind ensures the same chiller operates cor-
rectly even with a water content of just 2.5 l/kW and considera-
bly reduces outlet temperature fluctuations. The above graph
shows that outlet temperature fluctuations with QuickMind are
limited to 4.3 °C as opposed to 7.54°C if the traditional adjust-
ment system were used, without even ensuring an acceptable
minimum compressor start time.

Control unit with LCD display
(optional for NECS-ME 0152..0612)
Remote keyboard
As an alternative to the standard keyboard, the NECS has
a W3000 Compact operator panel with liquid crystal display.
(LCD)
This keyboard is standard for the NECS-ME 0604..1604 units.
This keyboard features a user interface for 3 European lan-
guages that can be selected by the user. Two of these are
preset (Italian and English) and the third can be chosen from
French, German, Spanish, Swedish and Russian (to specify
when ordering). This allows the control unit interface to be cho-
sen to suit the country of destination or, thanks to English, to be
completely independent for all geographical areas.
This same type of operator panel is also available as a remote
keyboard, to be connected to the unit by means of a serial con-
nection up to a maximum distance of 200 metres without power
supply (in this case power is supplied by the unit), or a maxi-
mum of 500 metres with dedicated local power supply.
Note
The remote keyboard may be connected to the unit without re-
placing the W3000 Base operator panel originally provided on
the unit. In this case the interface fitted locally on the unit is ex-
cluded, and access to the programming menus and the display
of the machine status is present only the additional keyboard at
remote level.
Instead, when the W3000 Base operator panel is replaced with
the W3000 Compact panel, control of the unit is possible at
both local and remote level. In this case the remote keyboard
faithfully reproduces what is shown on the control unit on board
the machine, further facilitating all the operations of configuring
and controlling the unit.

5.2 HYDRONIC UNIT
Available congurations
Hydronic kit with one pump
Hydronic kit with two pumps
Compact units Plug and Play.
The units in the NECS system are tted standard with a hy-
dronic group. This houses all the main hydraulic components,
thereby optimising hydraulic and electric installation space,
time and cost.
The innovative QuickMind control tted to the units in the NECS
system, has been designed to work on systems with a low wa-
ter content, offering highly professional alternatives to the in-
stallation of systems featuring storage units.
For special applications, a tank to install inside the unit is avail-
able on request.
2-pole low head pump
Horizontal one-piece centrifugal pump with one impeller, axial
suction and radial delivery, AISI 304L stainless steel pump body
impeller. The section of the shaft in contact with the liquid is
made from stainless steel. Mechanical seal made from compo-
nents in ceramics/carbon/NBR/AISI304. Three phase electric
motor protected to IP55, insulation class F, suitable for continu-
ous service.
2-pole high head pump
The hydronic group in all versions of the unit can be supplied
with a high head pump. In these cases, the pump features a
two-pole motor even in the silent-running versions.
Second pump
A second stand-by pump for high or low pressures is available
on request. The pumps are automatically exchanged on the
basis of a rotation programme and the stand-by pump cuts in
automatically if the primary pump fails. The two-pump hydron-
ic assembly is also tted with check valves to ensure the unit
works correctly.
Special pumps
For pumps with different congurations, please contact our
sales department.
Water-side mechanical lter (recommended)
Y-lter designed and built to capture the impurities in the hy-
draulic circuit. It is tted with a 0.9 mm stainless steel mesh car-
tridge which can be replaced without removing the valve body
from the piping.
The supply does not include the following accessories though
these are recommended to ensure correct system operation:
- MA Pressure gauges upline and downline from the unit.
- GF Flexible joints on piping.
- RI On-off valves
- T Outlet control thermometer
