5 Omega Sky Indoor water-condensed liquid chiller with semi-hermetic screw compressors, flooded shell-and-tube condenser and dry-expansion shell-and-tube evaporator. REFRIGERANT Refrigerant R513A standard. R513A is distinguished by its low environmental impact, with GWP=573. It is also a non-toxic and non-flammable fluid: A1 classification in accordance with ASHRAE; PED 2. These characteristics make R513A ideal for indoor units; they also facilitate adoption of the model in places where there are certain local requirements regarding the environmental impact caused by refrigerants. This has positive effects on transport, operation and maintenance and also on overall cost effectiveness, as regards possible taxation or restrictions on the use of refrigerants with high environmental impact. The model can be supplied with refrigerant R134a as option. STRUCTURE Consists of polyester powder coated hot dip galvanised sheet steel profiles (RAL 9005). The electrical control panel is made in a polyester powder-coated hot dip galvanised sheet steel box (RAL 7035). COMPRESSORS Semi-hermetic screw compressors with continuous capacity reduction of output capacity by 25 up to 100%, with high energy efficiency especially in cooling applications. The capacity reduction of the entire unit is always continuous, from the minimum capacity reduction step, based on the number of compressors, up to 100%. difference between delivery and suction. All the compressors are fitted with check valve on delivery side, metal mesh filter on suction side and electronic protection with temperature sensors directly inserted in the windings and on the delivery pipe. The machine is started and switched off with a forced 25% capacity reduction of each compressor and starting is of the star-delta type. All the compressors are supplied as standard with a crankcase heater and a delivery valve. They are installed on anti-vibration mounts in order to reduce vibration transmission to the structure. SOURCE-SIDE HEAT EXCHANGER Flooded shell-and-tube heat exchanger, with single water passage on tube side. Depending on size, the model consists of 1 or 2 condensers. Steel shell, and tube bundle made with copper tubes. The heads can be removed for tube inspection and cleaning. Victaulic couplings on water side (complete with nipple for connection). USER-SIDE HEAT EXCHANGER Dry-expansion shell-and-tube heat exchanger. Sized to maximize the efficiency of the unit, by keeping the overall dimensions and the refrigerant charge down to a minimum. The heat exchanger consists of a steel shell insulated with closed-cell foam material, while the tube bundle is made with copper tubes. The heads can be removed for tube inspection and cleaning. Victaulic couplings on water side (complete with nipple for connection). On the hydraulic connections of the heat exchanger, there are also pipe taps for the differential pressure switch, and wells for the temperature probes. REFRIGERANT CIRCUIT The model consists of sizes with 1 or 2 refrigerant circuits, each equipped with compressor. Each refrigerant circuit of the unit comprises: discharge valve for each compressor shut-off valve in the liquid line charging valves liquid sight glass replaceable solid cartridge dehydrator filter electronic expansion valve pressure transducers for reading the high and low pressure values and relevant evaporating and condensing temperatures a high pressure switch; a safety valve. The pipes of the refrigerant circuit and the heat exchanger on the user side are insulated with extruded closed-cell expanded elastomer. Compared to the mechanical expansion valve, the electronic expansion valve allows machine stability to be reached more quickly and better superheating control to maximize the use of the evaporator in all load conditions. This also acts as shut-off valve on the liquid line, thereby preventing hazardous refrigerant migrations during compressor stops. 3

6 ELECTRICAL CONTROL PANEL The electrical control panel is made in a painted galvanised sheet-iron box with forced ventilation and IP21 protection rating. The electrical control panel of the basic unit comprises: main disconnect switch fuses to protect the compressors and the auxiliary circuits compressor contactors phase monitor potential-free general alarm contacts single potential free operating contacts microprocessor controller with display accessible from the outside Capacitive backup battery for electronic expansion valve All the electrical cables inside the panel are numbered and the terminal board dedicated to the customer's connections is coloured blue so that it can be quickly identified in the panel. Standard power supply of the unit is 400V/3~/50Hz CONTROL BLUETHINK Programmable microprocessor control, having proprietary control algorithms. The control allows the following functions: water temperature adjustment, with outgoing water control freeze protection compressor timings automatic rotation of compressor starting sequence recording of the log of all machine inputs, outputs and states automatic rotation of compressor starting sequence recording of the alarm log management of capacity reduction of the compressors during starting, switching off and load tracking management of capacity reduction of the compressors in the event of operation outside the limits Connection resources The control includes the following connection resources: RS485 serial port with Modbus protocol Ethernet serial port with Modbus protocol; access to integrated web server digital input for remote setting of state (on/off) digital input for setting of summer/winter mode (only for HPW version) digital input for selection of double set point By default, the serial connections present as standard are enabled only for reading from BMS. Enabling of writing from BMS is to be requested when ordering. Main functions of the webserver As standard, the Bluethink controller integrates a web server with preloaded web page, which is accessed via password and user management on several levels. The web page allows the following functions to be carried out (some available only for users with advanced level rights): display of the main characteristics of the unit such as serial number, size, refrigerant display of the general status of the machine: water inlet and outlet temperatures on user side and source side, mode, evaporating and condensing pressures, suction and discharge temperatures display of the status of compressors and electronic expansion valves display of graphs of the main quantities, as trends in real time and also as log data display of alarm log remote setting of (on/off) remote setting of set point remote setting of time band remote setting of summer/winter mode Human-Machine Interface The control has a graphic display that allows the following information to be displayed: water inlet and outlet temperature set temperature and differential set points description of alarms hour meter of operation and number of start-ups of the unit, the compressors and the pumps (if present) high and low pressure values, and relevant condensing and evaporating temperatures superheating at compressor suction.

7 TESTING All the units are factory-tested and supplied complete with oil and refrigerant. VERSIONS Alongside the basic version of the unit, there are the following versions OH: non-reversible heat pump This is a heat pump for heating only. Compared to the basic version, both user-side and source-side heat exchangers are insulated. HPW: reversible heat pump on water side. This reversible heat pump is suitable for applications in which the user-side circuit and the source-side circuit can be exchanged with each other. Therefore, the fitter must make provision for a system of valves that will allow exchange of the two hydraulic circuits. If the seasonal mode change is carried out via remote signal or BMS, the unit can control motor-driven reversing valves (not supplied) so as to make this operation fully automatic. Compared to the basic version, both user-side and sourceside heat exchangers are insulated. LC: condenserless unit The unit does not have a source-side water heat exchanger so that it can be connected to a remote condenser. Compared to the basic version, the unit is supplied: with 3-way valve installed with weld-on refrigerant connections closed with copper plugs without refrigerant charge and charged with nitrogen with safety valves supplied The LC/DC version, complete with total heat recovery heat exchanger for each circuit, also includes an installed liquid receiver and safety valves in the machine. /DC: unit with total heat recovery condenser In addition to the basic set-up (chiller unit), the following are included: for each condenser, a section for recovering 100% of the condensation heat on each refrigerant circuit. a temperature probe at the inlet of each heat recovery heat exchanger potential free contact in the electrical control panel for activation of heat recovery. When required by the system, through the closing of a contact, the controller automatically manages activation of heat recovery. Heat recovery management is carried out through a control on the temperature of the return water. The controller also automatically manages safety deactivation of heat recovery, if the condensing pressure becomes too high, and switches to using the source-side heat exchanger. OPTIONS /LN: low noise unit The unit includes a soundproofing compartment on the compressor consisting of a rigid outer cowling made of galvanised and painted sheet metal (RAL 7035), lined with sound absorbing matting with high acoustic impedance material in between. /XLN: super low noise unit The unit includes: soundproofing compartment on the compressor consisting of a rigid outer cowling made of galvanised and painted sheet metal (RAL 7035), lined with sound absorbing matting with high acoustic impedance material in between. jacket on each compressor made of removable sound absorbing material. 5

8 DESCRIPTION OF ACCESSORIES Some accessories may be incompatible with each other even if not expressly indicated. Refrigerant R134 R134a Unit supplied with refrigerant R134a instead of R513A. Does not apply to LC versions. Refrigerant circuit accessories BC BK DVS MAFR RIC RPP Capacitive backup battery for electronic expansion valve When the compressors stop, the controller always closes the electronic expansion valve to prevent dangerous refrigerant migration. The presence of the backup battery ensures that the electronic valve is kept in closed position even when there is no power supply This accessory uses a condenser, and not an ordinary battery, as energy storage: this allows it to be unaffected by the memory effect of normal batteries and eliminates its need for maintenance. Brine Kit This accessory is compulsory if a water temperature set point lower than or equal to +3 C is used (if the unit is provided with double set point or variable set point, the lower set point is considered). The accessory consists of increased insulation and suitable sizing and calibration of some components. The inlet and outlet temperatures of the user-side exchanger must be given on ordering to allow correct setting of the alarm parameters and verification of the sizing of the expansion valve. The cooling set point can then be changed by the customer in an interval that, compared to the set point given on ordering, ranges from -1K up to the allowed limit temperature. The unit will be optimized to work at the set point temperature given on ordering. For different set points, the cooling capacity provided and the level of efficiency of the machine could decrease and move away from these conditions. This accessory obligatorily requires insertion of one of the condensation control options. Double safety valve With this accessory, instead of each individual safety valve per circuit, there is a "candelabrum" with two safety valves and a diverter valve for choosing the valve in operation. This allows the safety valves to be replaced without having to drain the machine and without having to stop it. Accessory installed in the machine for all versions (chiller, heat pump, LC/DC) excepting the LC version for which it is supplied with the unit. Pressure gauges The operating pressures of each circuit of the unit can be displayed on the control by accessing the relevant screens. Also, the machine can be fitted with pressure gauges (two for each circuit) installed in a clearly visible position. These allow reading in real time of the working pressures of the refrigerant gas on the low pressure side and on the high pressure side of each refrigerant circuit. Liquid receiver The adoption of this accessory always guarantees correct feeding of the expansion valve even when the unit is subjected to wide external air temperature ranges. Accessory supplied with the unit only for LC units, with the exception of the LC/DC version. For the LC/DC version, the receivers are already included and installed at the factory. Refrigerant leak detector with automatic pump down This accessory includes a refrigerant leak detector. Detection of a refrigerant leak is managed by the controller through a specific alarm and display of a specific icon on the display of the controller. For all the circuits of the unit, the alarm also starts the machine stopping procedure with pump down, confining all the refrigerant in the condenser. Accessory as an alternative to Refrigerant leak detector. 6

9 RPR RUBA SCU SIN VM2 VM3 VS Refrigerant leak detector This accessory includes a refrigerant leak detector. Detection of a refrigerant leak is managed by the controller through a specific alarm and display of a specific icon on the display of the controller. This alarm stops the unit. Accessory as an alternative to Refrigerant leak detector with automatic pump down. Compressor suction valves The valves situated on the suction side of the compressors allow the compressor to be isolated from the rest of the refrigerant circuit, so making the maintenance operations quicker and less invasive. The compressor discharge valve is standard on all compressors Cumulative 0-10V signal for condensation control This accessory requires a 0-10V output in the terminal board to carry out condensation control through a device outside the machine (2-way valve, 3-way valve, inverter-controlled pump). The signal is linked to the condensing pressure. The signal is cumulative and therefore the accessory is suitable for combination on units in which there is a single condensation control device located on the common branch of the source. Incompatible with condensation control with modulating valve. Independent 0-10V signals for condensation control For each refrigerant circuit, this accessory requires a 0-10V output in the terminal board to carry out condensation control through a device outside the machine (2-way valve, 3-way valve, inverter-controlled pump). The signal is linked to the condensing pressure. There is a signal for each refrigerant circuit and therefore the accessory is suitable for combination on units in which the sources of each circuit are managed independently. Incompatible with condensation control with modulating valve. Condensation control with 2-way modulating valve The accessory includes the supply of a 2-way modulating valve complete with servo control to be installed on the source-side hydraulic circuit (installation by the customer). The servo control is controlled via a 0-10V signal from the control depending on the condensing pressure. This accessory is to be used in applications where it is beneficial, when possible, to reduce the total flow rate of water coming from the source (for example, when well water is used). When the unit reaches the setpoint, the valve will be forced to close. Accessory supplied loose. Condensation control with 3-way modulating valve The accessory includes the supply of a 3-way modulating valve complete with servo control to be installed on the source-side hydraulic circuit (installation by the customer). The servo control is controlled via a 0-10V signal from the control depending on the condensing pressure. This accessory is to be used in applications where it is beneficial, when possible, to reduce the flow rate of water sent to the source-side heat exchanger (for example, when water from a loop is used). When the unit reaches the set point, the valve will be forced to total recirculation. Accessory supplied loose. Liquid line solenoid valve This accessory prevents refrigerant migration that could damage the compressor on starting. As standard on HPW and OH units. 7

In the case of the DC version, connections for the relevant hydraulic circuit are included. For LC/DC units, the connections refer to heat recovery only. Accessory supplied loose. FC/NG kit The kit is available only for the basic model (chiller). This option includes FC/NG management It consists of a module, supplied separately in a separate package. The module carries out the free-cooling mode without using glycol. The mode is managed by the BlueThink controller of the main chiller unit. The kit is fully panelled with epoxy polyester powder coated sheet metal (RAL 7035) and lined with matting made of sound absorbing and soundproofing material. The kit comprises: a water-water heat exchanger: brazed AISI stainless steel plate heat exchanger with anti-condensation insulation made of closed-cell insulating material. The heat exchanger makes the separation between the source side (glycol) and the user side (non-glycol) and allows transfer of cooling capacity from one side to the other during operation in free cooling mode. a 3-way modulating valve: the valve, complete with servo control, allows the free cooling circuit to be fed and the condensation control to be carried out when the unit is working in mixed chiller / free cooling mode. an inverter-controlled source-side pump: the inverter allows the water flow rate to be modulated on the source side in order to carry out condensation control or control of output capacity at the free cooling heat exchanger. The kit must be hydraulically and electrically connected to the main chiller unit; operation to be carried out on site by the customer. 8

11 Electrical accessories A41 Power supply 415/3/50 A43 Power supply 400/3/50 The standard power supply of the unit CA CP CSP Advanced control With this accessory, the advanced control is used also for sizes/versions provided with the parametric control as standard. Single potential free operating contacts For units fitted with this accessory, clean contacts from which the customer can acquire signals that are shown in the terminal board of the electrical control panel. Set point compensation depending on external air temperature For units fitted with this accessory, the set point of the unit is set so that it can vary between two values, a maximum and a minimum, depending on the external air temperature. The compensation ramp and the maximum and minimum values of the set point can be changed by the user. Unless otherwise specified in the order, the controller will be set to implement a positive compensation logic according to the temperatures shown in the following diagrams: Positive compensation Negative compensation SET POINT 2 17/12 C SET POINT 2 17/12 C Chiller SET POINT 1 12/7 C SET POINT 1 12/7 C 25 C 35 C External air temperature 25 C 35 C External air temperature SET POINT 2 40/45 C SET POINT 2 40/45 C Heat pump SET POINT 1 35/40 C 0 C 15 C External air temperature SET POINT 1 35/40 C 0 C 15 C External air temperature DAA Double power supply with automatic switching A motor-driven automatic switch to which to connect two separate power supply lines (for example, one from the mains power line and one from the uninterruptible power supply unit) is installed in the electrical control panel of the unit. The switching from one line to another is automatic and obligatorily requires passing through the OFF position. When this accessory is requested, the power supply of the unit must compulsorily include neutral. 9

12 DAM ENM FARE GFC IA LIID LIRA Double power supply with manual switching A manual switch to which to connect two separate power supply lines (for example, one from the mains power line and one from the uninterruptible power supply unit) is installed in the electrical control panel of the unit. The switching from one line to another is manual and obligatorily requires passing through the OFF position. Energy meter The accessory allows the main electrical quantities (including voltage, current, power) to be read on the three phases, via current transformer. Reading via RS485 port available on the accessory, which can be accessed via supervision system in general (on ModBus protocol). Fast Restart The Fast Restart accessory enables the controller to carry out a fast restart of the unit following a blackout, in order to reduce machine down times to a minimum. This accessory requires the provision of a power supply line dedicated to the controller (uninterruptible power supply unit installed by the customer) and a maximum and minimum voltage relay in the electrical control panel. In this way, the controller of the unit will always remain powered even during a blackout. Once the main power supply returns after a blackout, the starting of the first compressor takes place within 60 seconds and the full capacity of the unit is reached in about 180 seconds (a time that depends on the number of compressors and the instant load level). In order to protect component service life, the controller may carry out the Fast Restart procedure no more than 3 times in an hour and 5 times in one day. Also, to make it easier to carry out any maintenance on the power supply line dedicated to the controller, there is a selector switch inside the electrical control panel to allow the controller to be powered directly from the main power supply of the machine. Includes "Maximum and minimum voltage relay". FC/NG management This option is available only for the basic model (chiller). The option includes configuration of the BlueThink controller of the unit, in order to carry out the free-cooling mode, without using glycol. The option also includes integration in the machine of: free-cooling pump relay, consent for external dry cooler, system return probe and dry-cooler inlet and outlet probes. The components required for making the system, and also the hydraulic and electrical connections to the unit, are to be provided by the customer. More specifically, the system will consist of: a water-water heat exchanger that carries out the separation between the source side (glycol) and the user side (non-glycol). a 3-way modulating valve that feeds the free cooling circuit and carries out condensation control when the unit is working in mixed chiller/free cooling mode. a source-side pump Automatic circuit breakers (instead of fuses) This accessory requires the installation of automatic circuit breakers, instead of fuses, for the protection of auxiliary loads. Also, the same accessory uses automatic circuit breakers with adjustable thermal overload protection to protect the compressors. Limitation of the current absorbed by digital input When this accessory is requested, a digital input is prepared in the terminal board to activate the forced capacity reduction of the unit to a set fixed level. This accessory is useful when there is a need to necessarily limit the power absorbed by the unit as regards particular conditions. We point out that, in some conditions (for example, during hourly compressor rotation procedures), the controller could force the unit to operate at full capacity for limited periods of time. Absorbed current limitation with measurement of absorption For the unit equipped with this accessory, it is possible to set, directly in the control, a maximum current that can be absorbed by the machine. The control instantly checks the absorptions, through an amperometric transformer, and, in case of need, applies a dynamic forced capacity reduction able to always keep the absorbed current below the set threshold. 10

RIF Power factor correction to cosφ 0.95 With this accessory, an electrical control panel, containing power factor correction capacitors to make the cosφ of the unit greater than or equal to 0.95, is supplied with the unit. The capacitors should be connected (by the customer) to the electrical control panel of the unit in the specially prepared terminal board. Besides reducing the absorbed reactive power, the use of this accessory also allows the maximum absorbed current to be lowered. RMMT Maximum and minimum voltage relay This accessory constantly monitors the voltage value and the unit's power supply phase sequence. If the supply voltage does not fall within the set parameters or there is a phase reversal, an alarm is generated that stops the machine to prevent damage to its main parts SETD SETV Double set point from digital input The accessory allows you to preset two different operating set points and manage the change from one to the other through a digital signal. The set point temperatures must be specified when ordering. For optimization of the unit, reference will be made to the lower set point in chiller mode and the higher set point in heat pump mode. Unless otherwise specified in the order, the controller will be set at the factory with the following temperatures: in chiller mode, set point 1 to 7 C and set point 2 to 12 C in heat pump mode (only for HPW and OH units) set point 1 at 45 C and set point 2 at 40 C Variable set point with remote signal The accessory allows the set point to be varied continuously between two preset values, a maximum and a minimum, depending on an external signal that can be of the 0-1V, 0-10V or 4-20mA type. The set point temperatures and the type of signal to use for the adjustment must be specified when ordering. For optimization of the unit, reference will be made to the lower set point in chiller mode and the higher set point in heat pump mode. Unless otherwise specified in the order, the controller will be set at the factory with 0-10V analogue input and with the following temperatures: in chiller mode, 0V will correspond to a set point of 7 C and 10V will correspond to a set point of 12 C in heat pump mode (only for HPW and OH units), 0V will correspond to a set point of 45 C and 10V will correspond to a set point of 40 C 11

14 SOFT Electronic soft-starter Screw compressors (excluding inverter-controlled ones) are switched on using star-delta starting since this method allows very small effective average inrush currents to be obtained, but, as can be seen in the following diagrams, the connection change generates current peaks lasting a few ms. T [Nm] Δ I [A] Δ Y Y rpm If the unit is equipped with the electronic soft-starter accessory, the starting of each compressor becomes of the DOL (Direct On Line) type and therefore with a higher effective average inrush current, but with an acceleration ramp that allows elimination of the peaks that would be generated when changing from star to delta. rpm T [Nm] Δ I [A] Δ rpm rpm TERM Remote-controlled user terminal panel This accessory allows the terminal normally situated on the machine to be replicated on a support situated at a distance. It is particularly suitable when the unit is placed in an area that is not easily accessible. The accessory is supplied loose and is to be installed by the customer at a maximum distance of 120m from the unit. We advise using a cable of the following type: "TECO O.R. FE 2x2xAWG24 SN/ST/PUR".

AM Spring anti-vibration mounts These allow you to reduce the vibrations transmitted from the unit to the surface it is standing on. Accessory supplied loose. FLUS GABB KFW Flow switch As an alternative to the differential pressure switch (standard flow sensor), it is possible to request the paddle flow switch as accessory. This detects when there is no water flow to the user-side exchanger and sends a signal to the control of the unit that will stop the compressors to prevent damage to the exchangers.the flow switch is supplied loose (installation by the customer) and replaces the water differential pressure switch (standard). Packaging in wooden crate The unit is protected by a made-to-measure wooden crate. The accessory is mandatory if shipping by container is required. Water filter kit To protect the elements of the hydraulic circuit (in particular, the exchangers), there are Y filters that can stop and settle the particles that are normally present in the water flow and would otherwise settle in the more delicate parts of the hydraulic circuit and damage its heat exchange capacity. The kit involves the supply of a filter for each exchanger present in the machine. Installation of the water filter is mandatory even when it is not supplied as an accessory. Accessory supplied loose. Depending on the version of the unit, user side and source side filters are supplied, and for DC version units, heat recovery side filters are also supplied. 16
