1. PRODUCT PRESENTATION

IntroductionThis section contains general information on the NECS-ME range of products. For detailed information refer to the specifi c sections in this bulletin.

1.1 NECS-ME unitsThe 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 confi guration, and braze-welded plate heat exchangers.

1.2 R410A refrigerantThe use of R410A has improved the energy effi ciency 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 confi gurations with single or dual orthogonal pumps and high or low heads.

1.6 Silent runningThe NECS-ME chillers stand out for their silent running. If specifi cally requested, the casing of the unit can incorporate a layer of soundproofi ng made from high intermediate density conoid sandwich material which reduces noise suffi ciently to allow NECS-ME to be used in residential and commercial ar-eas without having to install it in dedicated rooms (technical rooms). The benefi t 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 installationAll 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 fi tted 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).

2.6 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, confi rm Climaveneta’s commitment to continually developing its electronics technol-ogy. The heat pumps, moreover, are fi tted with the original Cli-maveneta defrosting control system called “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 fl uctuations 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 fl uctuations. The above graph shows that outlet temperature fl uctuations 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 keyboardAs 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.

NoteThe 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 fi tted 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 confi guring and controlling the unit.

5.2 HYDRONIC UNIT

Available configurationsHydronic kit with one pumpHydronic kit with two pumps

Compact units Plug and Play.

The units in the NECS system are fitted 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 fitted 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 pumpHorizontal 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 pumpThe 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 pumpA 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 fitted with check valves to ensure the unit works correctly.

Special pumpsFor pumps with different configurations, please contact our sales department.

Water-side mechanical filter (recommended)Y-filter designed and built to capture the impurities in the hy-draulic circuit. It is fitted 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

10. REMOTE CONDENSERS

The new Climaveneta’s remote condensers NCE type are available within three different acoustical versions:

standard version /B• low-noise version /LN• super-silenced version /SL•

All versions are available for both horizontal (H) and vertical (V) air fl ow installation. The NCE remote condensers are provided with a single ventila-tion management. The choice of the number of circuits affects the refrigerant connections and / or the quantity of electrical signals provided to the fans speed management, according to the selected version.

Standard version (/B)Unit equipped with 6 poles motor fan and D connections (Del-ta). Fan speed management based on phase cutoff control is avai-lable as option. In this confi guration the units comes standard with a built-in electrical board.

Low-noise version (/LN)Unit equipped with 6 poles motor fan and Y connections (Star). Fan speed management based on phase cutoff control is avai-lable as option. In this confi guration the units comes standard

with a built-in electrical board.

Super-silenced Version SUPER-SILENZIATA (/SL)Unit equipped with 8 poles motor fan and Y connections (Star). Fan speed management based on frequency control is avai-lable as option (inverter). In this confi guration the units comes standard with a built-in the electrical board.

10.1 Electrical boardThe NCE remote condensers come standard without any elec-trical board. The NCE are provided with a junction box which includes the electrical connections of the fans.

The electrical board is provided as standard with all the fans speed management options (phase cutoff signal and inverter control), provided with all here below listed components:

main switch• fuses on mains• system on/off light signalling• power contactor for fans on/off • control circuit transformer• protection fuses on both primary and secondary circuits • auxiliary relay for thermal protection remote signalling.•
