MaestroSizes 6–7Introduction
CASINGIt is made with 1,2 mm galvanized steel for sizes 6-7, insulated with 10 mm polyolefin (PO) foam(class M1).
FAN ASSEMBLYConsists of quiet centrifugal fans with two impellers and a directly driven single phase, three speedmotor, 230V 50Hz, with external rotor, capacitor, insulation class B.
COILIt is manufactured from drawn copper tube and the aluminium fins are mechanically bonded ontothe tube by an expansion process.
The Maestro range Sabiana (sizes 6-7) is available with the combination of either 4 or 6 row coilswith the possibility to add a 2 row coil (4+2, 6+2 versions for 4 pipe systems).The connections are on the left hand side lookingfrom the air inlet of the unit (see picture anddrawing at page 20).On request the connections can be movedto the other side.
The heat exchanger is not suitable for usein corrosive atmosphere or in environmentswhere aluminium may be subject to corrosion.
FILTERThe filter is made of polypropylene cellular fabric regenerating filter.The filter frame of galvanized steel is inserted into sliding guides fastened to the internal structurefor easy insertion and removal of the filter.
CONDENSATE COLLECTION TRAYIt is made from galvanized steel insulated with 3 mm polyolefin (PO) foam (class M1).
Construction features

Example of calculation of the emissionat different speeds and air pressure drops
Model: Maestro MTL 66+2
Installation characteristics:Summer mode:Air temperature: + 25°C d.b. R.H. 50%Water temperature: + 8°C E.W.T. + 13°C L.W.T.
Winter mode:Air temperature: + 20°CWater temperature: + 60°C E.W.T. + 50°C L.W.T.
Requested air flow: 3400 m3/h
Requested available pressure: 110 Pa
Emission of Maestro 66+2 working• at medium speed (speed 2)• with 0 Pa of available pressure• with entering air temperature: 25°C- Air flow: 3570 m3/h (page 24 - MTL 66)- Total emission: 18250 W (page 24 - MTL 66)- Sensible emission: 14950 W (page 24 - MTL 66)- Heating: 23900 W (page 25 - MTL 6..+2)
Calculation of the emissionat requested flow:Define the “correction factor”between the requested air flowand the referring air flow (page 26):
Correction factor = 3400/3570 = 0,95
From Diagrams 1 and 2 definethe “variation in % of the emission”using the correction factorcalculated above.
- For the TOTAL emission = 0,97- For the SENSIBLE emission = 0,96- For the Heating = 0,96
The obtained emission for the unit is:
• TOTAL emission = 18250 x 0,97 = 17703 W• SENSIBLE emission = 14950 x 0,96 = 14352 W• Heating = 23900 x 0,96 = 22944 W
Calculation of the pressure drop:From the “Pressure drop” Diagramof Maestro MTL 64 with 3400 m3/h of air flow,we can find the pressure drop of the unit:
- ∆P air for the coil 6+2 = 22 Pa- ∆P air for the spigot plenum = 2 PaThe calculation is:- ∆P total air of Maestro = 22+2 = 24 Pa
Total pressure drop:
• Spigot pressure drop + Maestro pressure drop = 110 Pa + 24 Pa = 134 Pa
From the “Available pressure” Diagramof Maestro MTL 64 working at medium speedand with 3400 m3/h of air flow, we can find:
• Available pressure = 140 Pa = ~ 134 Pa

MaestroSizes 1÷7All the Maestro MTL units can be supplied with a wide range of controls, which allows managing one single unitor several units by using the Modbus RTU - RS 485. Units can be managed according to the Master/Slave logic(up to 20 units) or by supervisory components. The system consists in a QCV-MB board with T-MB included wallcontrol and a series of controls, such as the PSM-DI multifunction control and the Sabianet supervisory program.
To be used with valves with 3 points – 24 Volt actuator or with ON/OFF 230 V valves
The QCV-MB electronic board is set to carry out different functions and adjustment modes, in order to meet theinstallation requirements. These modes are selected by setting the configuration dip switches on the board.
• 2/4 pipe system.
• Fan ON/OFF thermostatic control.
• Valve thermostatic control and continuous ventilation.
• Valve and simultaneous ventilation 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:
• T-MB wall control.
• RS 485 serial connection to manage several fan coils in Master/Slave configuration or to create a supervisory network.

Using the special jumper present on the board, oneunit must be configured as the master, and all the others as slaves.
The T2 sensor can be combined with MB boards to be placedon the water supply pipe upstream 3 way valves (not to beused 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.

Another option available for the serial communication betweenthe units is the possibility to connect up to 60 Maestro MTLunits in series and manage them with just one wall mounted PSM-DI controller. The wall mounted controller can be usedto set the operating mode for each individual unit connected,display the operating conditions of each individual unit, andset the ON/OFF time sets for each day of the week (theprogram can be set for all the units and for a maximum often groups of units).If more than 60 units need to be connected, two or morecontrol panels must be used. Each unit must have a MB board.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 controlpoint.
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.
The PSM-DI panel cannot be usedtogether with the Sabianet management program (see next page).
Notes:• set the Dip Switches of each fan coil as illustrated in the installation manual, based on the required solutions.• it is possible to connect only one SIOS board per each PSM-DI control panel.• about “Priority pump function”: when just one unit calls for, the relay RL1 on the SIOS board is automatically activated to connect a hot water pump.• 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™ operating system (the program is providedpre-installed on a PC) and it works in a “stand alone” way, as an ordinary computer,so that it can be connected to a monitor, to a mouse and to a keyboard.By connecting an Ethernet cable is instead possible to work at a distance andvisualize the entire program setting-up through whatever browsers.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 and functional weekly program;
- possibility to access the historical operating data for each individual unit connected;
- possibility to save automatically every 6 h the data on SD support and to force the saving with a switch;
- possibility of data saving also on other items, as for example USB key;
- visualization of the saved configuration on a new ASUS PC.
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.

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 to displaythe actuators or external consents, such as motor or other.The SIOS boards can 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 to control several units inside a networkmanaged by Sabianet (default) or within a sub-network managed by BMS systems, that arenot provided by SABIANA (it is necessary to operate on a Dip Switch on the board).
Managed by SabianetThe Router-S in the standard version 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.);- allows creating a Master/Slave sub-network to be controlled as an indipendent group.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
Managed by BMS Systems which are not provided by SABIANAThe Router-S becomes an electronic board to use with BMS systems not supplied by SABIANA, only after having setthe Dip Switch on the board and so creating a Master/Slave sub-network to be controlled as an indipendent group.The number of Router-S to use is: - maximum 14 Router-S - maximum 15 Fan Coils per Router-S
