MD-600Version

Innovating and beautiful design, seven different sizes, high control flexibility, easy maintenance: thenew SkyStar chilled water cassette is the result of an extended technical and design developmentaimed at achieving the highest level in terms of performance, silent operation and controlpossibilities.

The air diffuser has an highly attractive aesthetical appearance, very innovative, and is also ableto 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 3bigger sizes have a dimension of 800x800 mm which allows the best outcome in terms of quiet-ness and of price/performance ratio for these high capacity models.

Every unit can be supplied with 1 battery (2 pipe system) and a possible electric heater or with2 batteries (4 pipe system). Each model can have fresh air intake and a remote air diffuser canbe connected to the unit.

The condensate pump is integralwith the unit, is very quiet and hasa maximum head of 650 mm.

In addition to the temperature andspeed standard controls, automaticspeed selection is also available. Morethan one unit can be connected toa single control, and the unit controlpanel can be installed in a position thatfacilitates the maintenance operation.Every unit can also be operated by themeans of an infra-red remote control.The SkyStar cassettes can also beconnected to the most commonautomatic building managementsystems.

It is also possible to use a completelywireless electronic control systembased on radio communication calledFree Sabiana, with great advantagesin terms of installation flexibility andmaximum precision in measuringroom temperature.

Finally, each unit can be equippedwith a low energy consumption electricmotor that is controlled by an invertercard that makes possible continuousair flow variations.

SkyStarAir throw

The air throw indicated in the tables must only be considered the maximum value, as it maychange significantly in relation to the dimensions of the room in which the appliance is installedand 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 speedis 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 45° (recommendedin heating mode), there will be a downwards throw, as illustrated in the second figure.

With adjustableair diffusion louvers at 30°


NOTE:On heating it must be payed attention to rooms where the floor temperatureis particularly low (for example less than 5°C).In this situation the floor can cool the lower layer of air to a level that stopthe uniform diffusion of the hot air coming from the unit,decreasing the throw figures shown in the table.

The cassette is fittedwith inlets for fresh air to be mixedwith return air inside the unit (Fig. 3).

The fresh air flow is limited to 20%of the total fan coil air flow at medium speedand 100 m3/h for each treated air inlet.

The units feature fresh air inletson three corners (no inlets on the fourth cornerbecause of the condensate pump inside the unit).

The fresh air inlets are designed for the insertion of standard 110 x 55 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 sectionmust be pushed into the unit (see Figures below). The duct is then fixed to the mounting plate.

Note: the fresh air must be filtered.

When the polluted air goes through themechanical pre-filter the particles � 50 μ areeliminated (powder, insects, etc).

Then the smallest particles (50 ÷ 0.01 μm) areexposed to an intensive ionizing field and are polarized (Phase 1).

The charged particles passing through the second filter section, arepushed back by the anode and attracted to the collection surfacesby a strong, induced magnetic field (Phase 2).

The air which leaves the unit is free from polluting particles.INLET

Operating principleof the electrostatic filter

The expression Indoor Air Quality (IAQ) covers all the procedures and methodologies used to improve thequality of the air we breathe in the places where we live and work, from all points of view, from temperatureto cleanliness, to relative humidity, etc. (EN 15251 and EN 13779). Thanks to its new patented electronic filter,the Crystall electrostatic filter totally eliminates the pollutants present in the air, including tobacco smoke,dust (PM10, PM2.5), fibres, microbiological substances such as bacteria, fungi, etc., which are harmful to humanhealth (source: OMS 2009). Purifying the air means not only greater well-being, but also energy saving, as thefresh air changes that are required to restore ideal climatic conditions and that entail greater consumption, aresignificantly reduced (it is sufficient to enter the quantity of air required to restore the optimum level of CO

2 - source:

EN 1379:2008). Moreover, according to the UNI 10339rev, air recirculated by the Crystall appliance can beconsidered as fresh air, to be added to the minimum requirements (0,5 ls/m2). Purifying the air with the SabianaCrystall appliance also entails no reduction of living room space, as the dimensions of the fan convectorare practically unchanged (just 3 cm higher). The positioning of the electronic filter allows simple and effectivemaintenance and, as it is easy to wash, its working life is practically unlimited. The modularity of the filtercomponents and their ease of mounting make the system extremely competitive in terms of cost comparedwith 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.

Indoor air quality (IAQ)

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 01 ordinary supplement no. 252”

The method for obtaining the air quality required in confined areas and thus succeeding in ensuring that thecontaminants 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).

SkyStarCRYSTALL

UNI EN 13779:2008 and UNI 10339rev StandardsThe example reproduced at the bottom of the page shows how, with adequate air filtering, it is possible todecrease considerably the quantity of fresh air to be brought into the environment (up to 3-4 times less); thethermal energy dissipated due to ventilation is in fact in direct proportion to the number of air changes, asindicated in the following equation: Qv = ΔT · R · D · C · Vol. 3600Qv = Thermal energy lost for ventilation - WattΔT = Indoor-Outdoor difference (T) - °CR = A.C.H.D = Air density - Kg/m3

C = Specific air heat - J/Kg-°CVol = Room size - m3

Fresh air flow rates according to the performance approach

The quantity and quality of recirculated air and outdoor air to be added is better specified in the prescriptive andperformance approach in Standards UNI EN 13779:2008 and soon to be released UNI 10339rev according tothe following simplified tables.

The Crystall electrostatic filtering system consists of two parts: the first is a plate type electronicactive filter and is fitted in the return air section of the cassette, while the second is an electroniccontrol and regulation board, fixed on the structure.All electrical connections are made during production. The installation of the SkyStar Sabianacassette fan coil unit incorporating the Crystall electronic filter is therefore similar to that of anormal unit: the only difference is the installation height, for which the filter dimensions musttaken 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 insulatingelements, forming a self-supporting ionisingframe, while the second consists of speciallight aluminium fins (collector).The two sections are installed above the return airgrille to make the extraction and maintenanceof the filter easier.Accessibility to sections to be cleaned is ensuredby easy-open plastic closures.The collector can be cleaned by washing withwater and ordinary detergents or steam jets(please consult the maintenance manual forfurther details).

Electronic board

Controls and regulates all functions of theelectrostatic filter.It is appropriately protected against any operatingdefects of the electrostatic filter. It supplies aconstant voltage to the electrodes when the mainssupply voltage varies (± 15%).The supply transformer is constructed with itsprimary and secondary coils physically separatedand wound onto separate cores.The energy consumption of the filter group is25 W (to which the electrical consumption of theCassette must be added).

Control and regulation commands

Units with Crystall electrostatic filter can becontrolled and regulated by the series of IAQcontrols that are already provided for CRCCarisma fan coils.

SkyStarFreeSabiana wireless control system

FreeSabiana

Free Sabiana is an innovative, fully wireless, electronic system for use withfan coil units, based on radio communication.

This technology provides installation flexibility and a more accuratemeasurement of the room temperature. The probe can be moved untilthe most suitable position is found, without the worry of changes in theenvironment layout and of its furniture and also without mounting it on a wall.If a new fan coil unit is added, no electrical wiring for the control system is

required: just define the control unit and the probe which regulates it. The improved measurement accuracy derivesfrom the possibility to position the probe near the typical location of the user: this enables to keep the temperatureexactly at the required value with more energy savings compared with a traditional measurement system.

Transmission is based on communication protocol IEE802.15.4, the most suitable way to transmit a relatively lowamount of information with very low consumption and high reliability.

The system has been certified by a leading independent body, officially recognized by the EU authorities and itssale has been authorized in all the EU and EFTA countries.

T-MB wall mounted control

All the controls for the ECM version and their functionsare described in detail from Page 43.

All the SkyStar units can be supplied in MB version. This version includesa 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 485 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 power board (mounted on models SK–MB and SK–ECM–MB)and a series of devices, such as the T-MB wall mounted control, the RT03 infra-red remote control,

the PSM-DI multifunction control and the Sabianet supervisory program.

SkyStar

The SkyStar 2 pipe models are available with electric heater that is controlled in place of the heating battery valve.

The electric heater is controlled in place of the hot water valve and not as integration to it.

The heater is hermetically sealed and supplied inside the battery pipes and therefore can be only factory mounted.

The electric heaters of the SK 12-22-32 units are for single phase 230V supply.

The electric heaters of the SK 42-52-62 units are for three phase 400V supply.

A specific electronic board is fitted in the unit control panel and it is connected to the heater and to the safetythermostat.

When the safety thermostat operates, it keeps open the heater supply relays on the electronic board.

The rearmement is by electric means, cutting off the supply to the unit.

Note: the cooling emission of the units is 95% of the emission in the tables of page 6.

Max. ambient temperature for Cassette unit with electric coil in heating mode: 25°C

Cassette unit operating limits with electric coil

The SkyStar ECM series uses an innovative brushless synchronous permanent magnet electricmotor controlled by an inverter card that is directly installed on the unit.

The air flow can be varied continuously with a 1-10 V signal from Sabiana controls or byindependent contollers (programmable controllers with a 1-10 V output).

The extreme efficiency, also at a low speed, makes possible a great reduction in electricconsumption (more than 75% less in comparison to a traditional motor) with absorptionvalues, under normal operating conditions, that are no greater than 10 Watt in the entire range.

The brushless motor is characterised by a constant synchronous speed, independently of theapplied load, that depends only on the motor power supply frequency, which is modulated bythe 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.

SK–ECM–MB version It consists of the MB electronic board (that integrates pump control) and the inverter board.

FAN ASSEMBLYThe 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 thatreduce turbulence, increasing efficiency and reducing noise.The fans are connected to a three phase permanent magnet brushless electronic motor that is controlledwith 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 aswitching 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 Vand frequency of 50 - 60 Hz.

HEAT EXCHANGERMade of copper tubes with bonded aluminium fins for maximum transfer contact.The batteries are with 2 or 3 rows for 2 pipe models and 2+1 rows for 4 pipe models (the heating row ison the inside part of the battery).For 4 pipe systems two versions are available:SK 14 and SK 44 supply an higher heating emission;SK 26, SK 36, SK 56 supply an higher cooling emission.The heat exchanger is not suitable for use in corrosive atmosphere or in environments where aluminiummay be subject to corrosion.

NOTE: On heating it must be payed attention to rooms where the floor temperature is particularly low (for example less than 5°C). In this situation the floor can cool the lower layer of air to a level that stop the uniform diffusion of the hot air coming from the unit, decreasing the throw figures shown in the table.

SkyStar ECM

SkyStarSkyStar ECM

The air throw indicated in the tables must only be considered the maximum value, as it maychange significantly in relation to the dimensions of the room in which the appliance is installedand 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 speedis 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 45° (recommendedin heating mode), there will be a downwards throw, as illustrated in the second figure.

Fresh air kitThis is used to introduce primary air into the environment directly through the diffuser. The kit includes a flow separatorto be fitted inside the cassette, and a circular fitting for connection to the flexible system ducting. The flow of air is sentdirectly to just one of the outlet louvers, without passing through the coil. The

air flow of fresh air introducedinto the environment dependon the inlet static pressure.PRT 800

The MB power electronic board,mounted as per standard on the SK–MBand SK–ECM–MB versions, is set to carry outdifferent functions and adjustment modes,in order to meet the installation requirements.

These modes are selectedby setting the configuration dip switcheson the board.

• 2/4 pipe system.

• Fan ON/OFF thermostatic control.

• Valve ON/OFF thermostatic control and continuous ventilation.

• Valve and simultaneous ventilation ON/OFF thermostatic control.

• Fan operation control depending on the coil temperature (cut-out T3 probe fitted), which can be activated only in heating mode or heating and cooling mode.

• Automatic switch of the operating mode by means of T2 water probe (optional) applied on the 2 pipe system.

• Seasonal switch by means of remote contact.

• ON/OFF of the fan coil by means of the remote contact (window or clock contact).

• Electric heater control.

By activating the cut-out T3 probe function, the fan is stopped in winter when the coil temperature is lower than 32°Cand started when the temperature reaches 36°C. In summer mode, the fan stops when the temperature inside thecoil exceeds 22°C and starts when it drops below 18°C.

The following connections are located on the power board:

• Receiver for infra-red remote control.

• T-MB wall mounted control.

• RS 485 serial connection to manage several fan coils in Master/Slave configuration or to create a supervisory network.

The T2 sensor can be combined with MB boards to be placed on the water supply pipe upstream 3 way valves(not to be used with 2 way valve).

The T2 sensor must be used as described below:

- Change-Over for 2-pipe system for the automatic switch of the operating mode. If water temperature is lower than 20°C, cooling mode is set; on the other hand, if water temperature exceeds 30°C, heating mode is set.

- It can be used on units with electric heater and hot water supply. The T2 priority probe activates the electric heater or water valve, depending on the water temperature detected. If water temperature exceeds 34°C, the water valve ON-OFF control is activated; on the other hand, if water temperature is lower than 30°C, the electric heater is activated.

T2 accessory for units with MB electronic board

A group of SkyStar MB can be connected via a serial link and can consequently be managed at the same timeby just one T-MB wall mounted control or RT03 infra-red remote control. Using the special jumper present onthe MB board, one unit must be configured as the master, and all the others as slaves. It is clear that the remotecontrol must be pointed at the receiver on the master unit. To avoid problems, it is recommended to install andconnect the receiver only on the master unit.

Another option available for the serial communication betweenthe units is the possibility to connect up to 60 Cassette units inseries and manage them with just one wall mounted PSM-DIcontroller. The wall mounted controller can be used to set theoperating mode for each individual unit connected, displaythe operating conditions of each individual unit, and set theON/OFF time sets for each day of the week (the programcan be set for all the units and for a maximum of two groupsof units).If more than 60 units need to be connected, two or morecontrollers must be used. Each wall mounted controller onlymanages the units it is connected to.The PSM-DI control is used to manage a series of fan coils,up to a maximum of 60 units (the maximum length of the RS 485connection cable must not exceed 800 m), from one single control point.

The PSM-DI control communicates via a serial line with all the units connected, with the possibility of controllingthem all together or individually. In fact, the unique address of each individual fan coil means that all the units canbe called at the same time, or the individual unit called, to perform the following functions:

- display the current operating mode, the fan speed, the set point;

- display the room temperature measured on the individual unit;

- turn all the units ON and OFF at the same time or alternatively each unit individually;

- change the operating mode (fan only, heating, cooling, automatic changeover);

- change the set point;

- modify the values and operation parameters of the fan speed.

Each function can then be sent to all the units connected, or alternatively to each individual unit.

Different set points or operating modes can be set for each individual unit.

The PSM-DI panel can also be used for the time management of the units over the week. Four ON times and fourOFF times can be set on the units for each day of the week. A different Temperature set that will be considered asOperation set for all connected appliances, can be set for each event. If the Temperature set is not entered for theindividual event, it must be set during programming for each individual unit or for the entire network.

Units without receiver or with receiver can be connected within the network: the former can receive instructions onlyfrom the PSM-DI wall mounted panel; while the latter can receive information from both the wall mounted panel(PSM-DI) and infra-red remote control. Use the infra-red remote control to force ON mode of the individual unit,if ON/OFF daily time programming has been set. The unit will regain the settings from the PSM-DI panel duringexecution of successive start-up program.

The PSM-DI panel cannot be usedtogether with the Sabianet management program (see next page).

Note: set the configuration Dip Switches of each fan coil as illustrated in the remote control use manual, based on the required solutions.

Note: the RS 485 network’s overall length must not exceed 700/800 metres.

Sabianet is a centralised control system for networks of Sabiana MB fan coils,based on software that runs on LINUX™.The Sabianet software offers a practical and economical solution for managingthe units, with the simple click of the mouse.The main characteristics include simplicity of use, an extremely complete andfunctional weekly program, and the possibility to access the historical operating datafor each individual appliance connected.

The program exploits all the potential of our units with remote controls, representing an additionto the latter.

The Sabianet program is a control tool that can be used as a replacement for the remote control, orin parallel, however the settings made using Sabianet can have priority over those made using theremote control.

The program can be used to:- Create uniform groups (groups of units on individual floors, in offices or rooms).- Save weekly programs configured for different types of operation (summer, winter, mid seasons, closing periods etc.); these can then be recalled and activated with a simple click of the mouse. Weekly on/off cycles can be set for individual units or groups of units.- Set the operating conditions for each individual unit or groups of units (operating mode, fan speed, temperature setting).- Set the set point limits for each individual unit or groups of units.- Switch each individual unit or groups of units ON or OFF.

An individual unit, a group ofunits or the entire network can be called so as to make modifications to the operating mode and the set point. Theuser can then check the operating status of each individual unit, read the room temperature, the coil temperatureand the operating status of the condensate drain pump or any alarms.

Time bands are available for each day of the week. The time and the type of operation to be performed by the unitcan be set for each band. The time and the operating parameters can then be displayed before being sent to theunit and implemented.

The “Weekly Program” can be used to set the unit operating parameters for each day of the week. Up to 20 differentweekly programs can be set.

The icon of the terminal unitprovides the following information:

- Unit name ( C01000001)

- Set temperature ( TSET )

- Room temperature ( TA )

- Unit status: ON or OFF

- Mode: • Summer • Auto

• Winter • Fan only

- Fan speed: • Low • High

• Medium • AutoFan

The “MONITORING” SCREEN shows the units thatare connected to the network and scanned by the program.

SIOS is a board equipped with 8 relays with potential free contact to control the activationor deactivation of remote electric utilities. Moreover, the board has 8 digital inlets todisplay the actuators or external consents, such as motor or other. The SIOS boardscan be connected:

- inside a network managed by Sabianet;

- to a PSM-DI panel (one SIOS for each PSM-DI panel).

The Router-S is an electronic board that:

- allows creating networks with more than 60 units (minimum 2 Router-S are required) or to divide the network (per floor, building, etc.);

- it allows creating a Master/Slave sub-network to be controlled as an indipendent group.

The Router-S can be used only inside a network managed by Sabianet.

The number of Router-S to be used is: - up to 60 units: no Router-S - from 61 to 120 units: 2 Router-S - every 60 subsequent units: 1 additional Router-S

Introduction

The MCT version has been designed for all environments where false ceilings are not featuredor cannot be constructed.The cover cabinet fits perfectly to the air intake and outlet diffuser, maintaining the appealingdesign that defines the SkyStar series. The water fittings can be turned to point upwards.

The MCT series includes 7 models, with an installation height of up to 5 m, thanks to the highlyflexible adjustment of the air distribution louvers.

All the technical specifications described on the previous pages remain the same, while keepingin 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 befitted after having installed the SkyStar unit and completed the water and electrical connections.
