Introduction Innovating and beautiful design, seven different sizes, high control flexibility, easy maintenance: the new chilled water cassette is the result of an extended technical and design development aimed at achieving the highest level in terms of performance, silent operation and control possibilities. The air diffuser has an highly attractive aesthetical appearance, very innovative, and is also able to offer the best air distribution performance thanks to long computer studies and laboratory tests. The standard colour is RAL 9003, other colours available on request. The 4 smaller sizes are designed to fit into 600x600 mm false ceiling standard modules. The 3 bigger sizes have a dimension of 800x800 mm which allows the best outcome in terms of quietness and of price/performance ratio for these high capacity models. Every unit can be supplied with battery (2 pipe system) and a possible electric heater or with 2 batteries (4 pipe system). Each model can have fresh air intake and a remote air diffuser can be connected to the unit. The condensate pump is integral with the unit, is very quiet and has a maximum head of 60 mm. In addition to temperature and speed standard controls, automatic speed selection is also available. More than one unit can be connected to a single control, and the unit control panel can be installed in a remote position that facilitates the maintenance operation. All the units can be supplied in MB version. This version allows a wide range of controls, including the infra-red remote control, which can manage one single unit or several units by using the Modbus RTU - RS 48 communication protocol. The units can be connected to the most common automatic building management systems. It is also possible to use a completely wireless electronic control system based on radio communication called Free Sabiana, with great advantages in terms of installation flexibility and maximum precision in measuring room temperature. Finally, each unit can be equipped with a low energy consumption electric motor that is controlled by an inverter card that makes possible continuous air variations. 3
Main components INTAE GRID AND DISTRIBUTION OF THE AIR Intake grids, frame and adjustable air distribution louvers on each side, made from ABS. HTA version : white ABS, RAL 9003 HTB version : with intake grid, frame and louvers, choice of one colour only HTC version : with intake grid and louvers, choice of one colour, plus white ABS frame RAL 9003 HTD version : with louvers, choice of one colour, while the grid and frame are made from ABS, RAL 9003 MD-600 version : metal diffuser painted in RAL 9003 white colour with 600x600 dimension to perfectly fit into the false ceiling standard modules without overlapping parts (800x800 model is not available). CASING Is made from galvanized steel with internal thermal insulation with polyolefin (PO) foam (class M) and external anti-condensate lining. CONTROL PANEL Made of an external box with the control electronic board with an easily accessible terminal board. FAN ASSEMBLY The fan assembly, which is mounted on anti-vibrating supports, is extremely silent. The radial fan has been designed to optimise performance, using wing profile blades with a shape that reduces turbulence, increasing efficiency and reducing noise. The single air inlet radial fan is connected to a 6 speed electric motor with single phase 230V/0Hz supply, class B insulation and integrated lixon thermal contact for motor protection. The units are supplied with 3 standard speeds connected and it is possible to change them on site if necessary. COIL Made of copper tubes with bonded aluminium fins for maximum transfer contact. The coil has, 2 or 3 rows for 2 pipe models and 2+ rows for 4 pipe models (the heating row is on the inside part of the coil). For 4 pipe systems two versions are available: S 04, S 4, S 24, S 34, S 44, S 4, S 64 supply an higher heating emission; S 26, S 36, S 6, S 66 supply an higher cooling emission. The heat exchanger is not suitable for use in corrosive atmosphere or in environments where aluminium may be subject to corrosion. CONDENSATE COLLECTION TRAY density ABS polystyrene foam condensate tray, shaped in order to optimize the air diffusion, fire retardant rating B to DIN 402. AIR FILTER Synthetic washable filter, easily removable. CONDENSATE PUMP Float switch centrifugal pump with 60 mm of maximum head, integral to the unit and wired to the control panel on the outside of the casing. VALVE SET Two or three way valves for ON/OFF operation, with pipe mounting kit and thermostatic actuator. 4

Fresh air supply - Fresh air connection The cassette is fitted with inlets for fresh air to be mixed with return air inside the unit (Fig. 3). FRESH AIR INLET The fresh air is limited to 20% of the total fan coil air at medium speed and 00 m 3 /h for each treated air inlet. The units feature fresh air inlets on three corners (no inlets on the fourth corner because of the condensate pump inside the unit). AIR INTAE Fresh air connection The fresh air inlets are designed for the insertion of standard 0 x mm rectangular ducts. The air duct is connected quickly and easily. After removing the blank and the insulation inside the unit, the mounting plate is rolled back and the air duct with its V-shaped section must be pushed into the unit (see Figures below). The duct is then fixed to the mounting plate. Note: the fresh air must be filtered. 2 3 4 MAIN AIR INLET Accessory Fresh air connection - Identification CAP - Code 607800 (see page 4) AIR INTAE Air distribution - Air distribution connection Two air outlets are provided on the side of the unit for connection to separate supply air outlets.

Accessories Balancing valves independent from the system pressure The balancing valve and a combined 2 way valve allow the regulation of the water value autonomously, regardless of the system pressure, and the control of the by using an ON/OFF electro-thermal actuator. The balancing valve allows you to balance the hydraulic system by supplying the required water, for each fan- coil, and to maintain it even under partial load conditions. A graduated ring nut placed under the valve allows you to set the rate value and also allows direct reading of the set value. Valve operation logic p is the valve inlet pressure. p3 is the outlet pressure. p2 is the diaphragm activation pressure, which allows differential pressure p2 p3 to be maintained at a constant value, in order to guarantee the water to at the set value. The minimum differential pressure p p3, required to guarantee the correct value of the set water rate, is indicated in the diagrams on page 7. This is an essential factor to size the system pressure drop and pump pressure head. The rate is kept at a constant value only if the valve pressure drop is higher than the indicated value. Minimum operating differential pressure The minimum differential pressure and the balancing valve pressure drop must be considered to size the system pumps. Flow rate is constant if the pressure drop is higher than that indicated in the diagrams on page 7. The following diagram shows an example of the rate trend according to the pressure drop and calibration required. Example DN Model 6 LEGEND: Qw = rate (l/h) Pd = Min. differential pressure p p3 (bar) Q = Area with inconstant water Q2 = Area with constant water S = Position of the adjustment valve plunger M = Position of the knob
Accessories The valve upstream-downstream minimum differential pressure ( p p3 ), which depends on the valve calibration value, must be exceeded to access the constant rate field. DN Model DN 20 Model LEGEND: Pd = Min. differential pressure p p3 (bar) E.g., when sizing the system pump, in which the DN valves will be installed and in which 40 l/h are constantly required for each device, consider a useful pressure of 0.3 bar (to compensate the pressure drop of the valve) for each balancing valve. Therefore, the pressure drop values produced by the system balancing valves must be summed and the pump must be sized to produce a pressure equal to or greater than the value obtained previously. Benefits Reduced dimensions. Easy installation on 2 or 4 pipe devices. Pre-regulation of the nominal value set even with installed actuator. Easy display of the nominal value set. Nominal values are indicated in 0 l/h without any conversion. Guarantee of constant rate set even with partial loads. Pre-regulation can be blocked and leaded with the locking ring.

Crystall Introduction Cassette can be equipped with the innovative plate type electrostatic filter, Crystall, combining air treatment and purifying in a single product. The electronic filter is patented and certified according to Standard UNI 24. Dimensions S 0 / / 2 / 3 (Model 600 x 600) S 4 / / 6 (Model 800 x 800) 20
Crystall Operating principle of the electrostatic filter When the polluted air goes through the mechanical pre-filter the particles 0 µ are eliminated (powder, insects, etc). OUTLET OF CLEAN AIR Collection surface Then the smallest particles (0 0.0 μm) are exposed to an intensive ionizing field and are polarized (Phase ). Air without particles < µm PHASE 2 Inducted anode Polarized electrode The charged particles passing through the second filter section, are pushed back by the anode and attracted to the collection surfaces by a strong, induced magnetic field (Phase 2). The air which leaves the unit is free from polluting particles. Electrostatic filter Air without particles 0 µm Pre-filter PHASE Ionic field Elimination of the biggest particles INLET OF POLLUTED AIR Indoor air quality (IAQ) The expression Indoor Air Quality (IAQ) covers all the procedures and methodologies used to improve the quality of the air we breathe in the places where we live and work, from all points of view, from temperature to cleanliness, to relative humidity, etc. (EN 2 and EN 3779). Thanks to its new patented electronic filter, the Crystall electrostatic filter totally eliminates the pollutants present in the air, including tobacco smoke, dust (PM0, PM2.), fibres, microbiological substances such as bacteria, fungi, etc., which are harmful to human health (source: OMS 2009). Purifying the air means not only greater well-being, but also energy saving, as the fresh air changes that are required to restore ideal climatic conditions and that entail greater consumption, are significantly reduced (it is sufficient to enter the quantity of air required to restore the optimum level of CO 2 - source: EN 379:2008). Moreover, according to the UNI 0339rev, air recirculated by the Crystall appliance can be considered as fresh air, to be added to the minimum requirements (0, ls/m2). Purifying the air with the Sabiana Crystall appliance also entails no reduction of living room space, as the dimensions of the fan convector are practically unchanged (just 3 cm higher). The positioning of the electronic filter allows simple and effective maintenance and, as it is easy to wash, its working life is practically unlimited. The modularity of the filter components and their ease of mounting make the system extremely competitive in terms of cost compared with other types of filters present on the market. In spring and autumn, if air conditioning/heating is not required, the appliance acts simply as an air purifier. Standards and legislation THE AMBIENT CONDITION IS ACCEPTABLE WHEN: Microclimatic parameters are normal 80% of people are satisfied by the quality of air Specific internal contaminants are not in harmful concentrations Guidelines for the protection and promotion of health in confined areas O.G. No. 276 dated 27 Nov 0 ordinary supplement no. 22 The method for obtaining the air quality required in confined areas and thus succeeding in ensuring that the contaminants present are in concentrations less than those considered dangerous to health are: Prescriptive approach: ventilation of the internal area using only properly filtered fresh air, in the quantity and quality needed to dilute the internal contaminants in order to reach the required maximum acceptable concentration values (see WHO limits). Performance approach: ventilation with fresh air and recirculated air from the same area, both properly filtered, in the quantity and quality needed to dilute the internal contaminants in order to reach the required maximum acceptable concentration values (see WHO limits). 2
Crystall The quantity and quality of recirculated air and outdoor air to be added is better specified in the prescriptive and performance approach in Standards UNI EN 3779:2008 and soon to be released UNI 0339rev according to the following simplified tables.

D = Air density - g/m 3 C = Specific air heat - J/g- C Vol = Room size - m 3 22
Crystall Construction features The Crystall electrostatic filtering system consists of two parts: the first is a plate type electronic active filter and is fitted in the return air section of the cassette, while the second is an electronic control and regulation board, fixed on the structure. All electrical connections are made during production. The installation of the Sabiana cassette fan coil unit incorporating the Crystall electronic filter is therefore similar to that of a normal unit: the only difference is the installation height, for which the filter dimensions must taken into account. Crystall filters are not suitable for ECM and electric heater versions. Active plate type electronic filter The filtering element consists of two sections: the first consists of electrodes and insulating elements, forming a self-supporting ionising frame, while the second consists of special light aluminium fins (collector). The two sections are installed above the return air grille to make the extraction and maintenance of the filter easier. Accessibility to sections to be cleaned is ensured by easy-open plastic closures. The collector can be cleaned by washing with water and ordinary detergents or steam jets (please consult the maintenance manual for further details). Electronic board Controls and regulates all functions of the electrostatic filter. It is appropriately protected against any operating defects of the electrostatic filter. It supplies a constant voltage to the electrodes when the mains supply voltage varies (± %). The supply transformer is constructed with its primary and secondary coils physically separated and wound onto separate cores. The energy consumption of the filter group is 2 W (to which the electrical consumption of the Cassette must be added). Control and regulation commands Units with Crystall electrostatic filter can be controlled and regulated by the series of IAQ controls that are already provided for CRC Carisma fan coils. - Diffuser with return air grid 2 - Active plate type electrostatic filter 3 - Plastic opening 4 - Insulation - Filter containment frame 6 - Electronic board 7 - Cassette 23
Wall electronic controls All the units can be supplied with a wide range of controls that allows managing one single unit or several units (by using speed switches or the power unit). The room temperature can be controlled through electronic room thermostats, with different solutions according to every ambient conditions. The options range from the basic 3 speed control WM-3V to the highly sophisticated WM-T and WM-TQR electronic room thermostats that regulate the room temperature and are suitable when the user wants to set the fan speed. The most evolved WM-AU, T-MB, TMO-03-SV2 and FreeSabiana versions allow both the manual and the automatic speed switch. WM-3V WM-T WM-TQR WM-AU T-MB TMO-03-SV2 T2T FreeSabiana wireless control All the controls are described in detail in the Fan Coil Control Range literature. 24
Controls for S MB versions All the units can be supplied in MB version. This version includes a wide range of controls, including the infra-red remote control, which allows managing one single unit or several units by using the Modbus RTU - RS 48 communication protocol. Units can be managed according to the Master/Slave logic (up to 20 units) or by supervisory components. The system consists in a MB board (mounted on models S MB and S ECM MB) and a series of controls, such as the T-MB wall control, the RT03 infra-red remote control, the PSM-DI multifunction control and the Sabianet supervisory program.

ECM ECM Introduction The ECM series uses an innovative brushless synchronous permanent magnet electric motor controlled by an inverter card that is directly installed on the unit. The air can be varied continuously with a -0 V signal from Sabiana controls or by independent contollers (programmable controllers with a -0 V output). The extreme efficiency, also at a low speed, makes possible a great reduction in electric consumption (more than 7% less in comparison to a traditional motor) with absorption values, under normal operating conditions, that are no greater than 0 Watt in the entire range. The brushless motor is characterised by a constant synchronous speed, independently of the applied load, that depends only on the motor power supply frequency, which is modulated by the inverter. It consumes less because: The motor always works at its point of maximum efficiency. In the brushless motor, the rotor s permanent magnets generate the magnetising power autonomously. The motor always operates at the synchronous speed, as a result there are no induced currents that reduce efficiency. The main advantages are: Large reduction in energy consumption, thanks to an optimal response to the thermal load of the environment during every moment of the day. Operating silence at all rotation speeds. Ability to operate at any rotation speed. Motor Absorption = S = S-ECM 28
ECM ECM Main components INTAE GRID AND DISTRIBUTION OF THE AIR Intake grids, frame and adjustable air distribution louvers on each side, made from ABS. HTA version : white ABS, RAL 9003 HTB version : with intake grid, frame and louvers, choice of one colour only HTC version : with intake grid and louvers, choice of one colour, plus white ABS frame RAL 9003 HTD version : with louvers, choice of one colour, while the grid and frame are made from ABS, RAL 9003 MD-600 version : metal diffuser painted in RAL 9003 white colour with 600x600 dimension to perfectly fit into the false ceiling standard modules without overlapping parts (800x800 model is not available). CASING Is made from galvanized steel with internal thermal insulation with polyolefin (PO) foam (class M) and external anti-condensate lining. CONTROL EQUIPMENT S ECM version It consists of the pump control circuit board and the inverter circuit board. S ECM MB version It consists of the MB electronic board (that integrates pump control) and the inverter board. FAN ASSEMBLY The fan assembly, which is mounted on anti-vibrating supports, is extremely silent. The radial fan has been designed to optimise performance, using wing profile blades with a shape that reduces turbulence, increasing efficiency and reducing noise. The fans are connected to a three phase permanent magnet brushless electronic motor that is controlled with reconstructed current according to a BLAC sinusoidal wave. The inverter board that controls the motor operation is powered by 230 Volt, single-phase and, with a switching system, it generates a three-phase frequency modulated, wave form power supply. The electric power supply required for the machine is therefore single-phase with voltage of 230-240 V and frequency of 0-60 Hz. COIL Made of copper tubes with bonded aluminium fins for maximum transfer contact. The coil has 2 or 3 rows for 2 pipe models and 2+ rows for 4 pipe models (the heating row is on the inside part of the coil). For 4 pipe systems two versions are available: S 4 and S 44 supply an higher heating emission; S 26, S 36, S 6 supply an higher cooling emission. The heat exchanger is not suitable for use in corrosive atmosphere or in environments where aluminium may be subject to corrosion. CONDENSATE COLLECTION TRAY density ABS polystyrene foam condensate tray, shaped in order to optimize the air diffusion, fire retardant rating B to DIN 402. AIR FILTER Synthetic washable filter, easily removable. CONDENSATE PUMP Float switch centrifugal pump with 60 mm of maximum head, integral to the unit and wired to the control panel on the outside of the casing. VALVE SET Two or three way valves for ON/OFF operation, with pipe mounting kit and thermostatic actuator. 29

ECM ECM Air throw The air throw indicated in the tables must only be considered the maximum value, as it may change significantly in relation to the dimensions of the room in which the appliance is installed and the positioning of the furniture in the room. The useful throw L refers to the distance between the unit and the point where the air speed is 0.2 m/sec; if the louver has a gradient of 30 (recommended in cooling mode), the so-called Coanda effect will occur, illustrated in the first figure, while at a gradient of 4 (recommended in heating mode), there will be a downwards throw, as illustrated in the second figure.

ECM ECM Wall electronic controls All the units can be supplied with a wide range of controls that allows managing one single unit or several units (by using the power unit). The room temperature can be controlled through electronic room thermostats, with different solutions according to every ambient conditions. The electronic thermostats WM-AU, T-MB and WM-S-ECM rule the room temperature precisely and are suitable for each of those situations, into which it is the user to decide between the manual or the automatic fan speed. WM-AU T-MB WM-S-ECM All the controls are described in detail in the Fan Coil Control Range literature. 40
ECM ECM Controls for S ECM MB versions All the ECM units can be supplied in MB version. This version includes a wide range of controls, including the infra-red remote control, which allows managing one single unit or several units by using the Modbus RTU - RS 48 communication protocol. Units can be managed according to the Master/Slave logic (up to 20 units) or by supervisory components. The system consists in a MB board (mounted on models S MB and S ECM MB) and a series of controls, such as the T-MB wall control, the RT03 infra-red remote control, the PSM-DI multifunction control and the Sabianet supervisory program.

ECM ECM Electric heater S-ECM-E The Cassette 2 pipe models are available with electric resistance that is controlled in place of the heating battery valve. The electric resistance is controlled in place of the hot water valve and not as integration to it. The resistance is hermetically sealed and supplied inside the battery pipes and therefore can be only factory mounted. The electric resistances of the units are for single phase 230V supply. The Cassette includes no. 2 safety thermostats which intervene in case of internal over- heating, opening an auxiliary power relay (included in the shunt box) which stops the power supply to the resistances.

MCT MCT Introduction The MCT version has been designed for all environments where false ceilings are not featured or cannot be constructed. The cover cabinet fits perfectly to the air intake and outlet diffuser, maintaining the appealing design that defines the series. The water fittings can be turned to point upwards. The MCT series includes 7 models, with an installation height of up to m, thanks to the highly flexible adjustment of the air distribution louvers. All the technical specifications described on the previous pages remain the same, while keeping in mind that: - the MCT series features one coil only (two pipe systems) - there is no possibility of fresh air intake - there is no possibility of additional electric heater The MCT version features a special casing delivered in separate packaging; this must only be fitted after having installed the unit and completed the water and electrical connections. 43
