1. PRODUCT PRESENTATION Introduction This section contains general information on the range of products. For detailed information refer to the specifi c sections in this bulletin. 1.1 units The chillers are a range of remote-condensation liquid 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-compressor unit) tandem confi guration, and braze-welded plate heat exchangers. 1.2 R410A refrigerant The 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 systems. 1.4 Integral control and adjustment The evaporating unit is supplied complete with integral microprocessor control and optional connection to a remote condenser. 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. 1.7 Ease of installation All the connections of the 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 positioned near the perimeter walls without compromising access to the internal components during maintenance. 1.8 Versatility On request, the units can be fi tted with an integrated pump unit for circulating the liquid in the system, with a high or low head depending on the various application requirements. 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 preventing risks of mechanical breakage) and to manually select one of the two pumps. 1.9 Usability The electronic controller of the features a programmable 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). 1.6 Silent running The 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 to be used in residential and commercial areas 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. III NECS_ME_0152_1604_201004_GB

2.6 Control unit with LCD display (standard) The new W3000 Base control unit is installed on all 0152..0612 units. The new W3000SE Compact control unit is installed on all 0604..1604 units. Main functions: QuickMind, local and remote FWS supervision, dual set point management, etc, confi rm Climaveneta s commitment to continually developing its electronics technology. The heat pumps, moreover, are fi tted with the original Climaveneta defrosting control system called Autotuning Defrost which considerably reduces defrosting times, thus improving the energy performance of the unit. Interfaces with BMS systems: METASYS, MODBUS, LONWORKS, SIEMENS, TREND. QuickMind is a special control unit which monitors the main operating parameters, predicts system behaviour and anticipates 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 temperature 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 adjustment system, the minimum recommended water content is 5.5 l/kw. QuickMind ensures the same chiller operates correctly even with a water content of just 2.5 l/kw and considerably 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 adjustment system were used, without even ensuring an acceptable minimum compressor start time. Black Box logs data relative to 200 alarm events which can be printed with a personal computer. 12 11 10 11.34 Step-wise regulation Regolazione a gradini Variation output temperature Variazione temperatura in uscita Output temperature ( C) Temperatura in uscita ( C) 9 8 7 6 5 4 Quickmind 5.9 4.3 7.54 4.56 Not acceptable minimum starting time compressors Tempo minimo di accensione compressore non accettabile 3,68 3.52 3.52 3.52 3.52 3.52 3.52 3.9 3 3.5 3.3 3.2 3.1 3 3 2 0.5 1.5 2.5 3.5 4.5 5.5 6.5 7.5 8.5 9.5 Minimum water content in the plant lt/kw 3 10.5 11 3 NECS_ME_0152_1604_201004_GB

Control unit with LCD display (optional for 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 0604..1604 units. This keyboard features a user interface for 3 European languages 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 chosen 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 connection up to a maximum distance of 200 metres without power supply (in this case power is supplied by the unit), or a maximum of 500 metres with dedicated local power supply. Note The remote keyboard may be connected to the unit without replacing the W3000 Base operator panel originally provided on the unit. In this case the interface fi tted locally on the unit is excluded, 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. 4 NECS_ME_0152_1604_201004_GB
