CASING

It is made with galvanized steel insulated with polyolefin (PO) foam (class M1).

FAN ASSEMBLY

Consists of quiet centrifugal fans in galvanized steel with two impellers and a directly driven singlephase, five speed motor, 230V 50Hz, with capacitor, insulation class B.

COIL

It is manufactured from drawn copper tube and the aluminium fins are mechanically bonded ontothe tube by an expansion process.

The DFCO range (sizes 1÷5) is available with the combination of either 3 or 4 row coils with thepossibility to add a 1 or 2 row coil (3+1, 4+1, 3+2, 4+2 versions for 4 pipe systems).The connections are on the left hand side looking

from the air inlet of the unit (see picture and

drawing at page 4).

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.

FILTER

The 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 TRAY

It is made from galvanized steel insulated with polyolefin (PO) foam (class M1).

CASING

It is made with galvanized steel insulated with polyolefin (PO) foam (class M1).

FAN ASSEMBLY

Consists of quiet centrifugal fans in galvanized steel with two impellers and a directly driven singlephase, three speed motor, 230V 50Hz, with external rotor, capacitor, insulation class B.

COIL

It is manufactured from drawn copper tube and the aluminium fins are mechanically bonded ontothe tube by an expansion process.

The DFCO range (sizes 6-7) is available with the combination of either 4 or 6 row coils with thepossibility to add a 2 row coil (4+2, 6+2 versions for 4 pipe systems).The connections are on the left hand side looking

from the air inlet of the unit (see picture and

drawing 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.

FILTER

The 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 TRAY

It is made from galvanized steel insulated with polyolefin (PO) foam (class M1).

Example of calculation of the emissionat different speeds and air pressure drops

Model: DFCO 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 DFCO 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 - DFCO 66)- Total emission: 18250 W (page 24 - DFCO 66)- Sensible emission: 14950 W (page 24 - DFCO 66)- Heating: 23900 W (page 25 - DFCO 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 DFCO 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 DFCO = 22+2 = 24 Pa

Total pressure drop:

• Spigot pressure drop + DFCO pressure drop = 110 Pa + 24 Pa = 134 Pa

From the “Available pressure” Diagramof DFCO 64 working at medium speedand with 3400 m3/h of air flow, we can find:

• Available pressure = 140 Pa = ~ 134 Pa

A group of DFCO units with QCV-MB control board can be connected via a serial link and can consequently bemanaged at the same time by just one T-MB wall control. Using the special jumper present on the board, one unitmust be configured as the master, and all the others as slaves.

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.

Another option available for the serial communication betweenthe units is the possibility to connect up to 60 DFCO 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 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 NET 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.

NET program for managing a network of MB fan coils

NET is a centralised control system for networks of MB fan coils,based on software that runs on LINUX™ (the program is providedpre-installed on a PC).The NET software offers a practical and economical solutionfor managing the units, with the simple click of the mouse.The main characteristics include simplicity of use,an extremely complete and functional weekly program, and the possibility to accessthe historical operating data for each individual unit connected.

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.

o aaccess

The main program screen can display and interact with the entire network of units. 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.
