The fan coil unit has been designed around a platform of models, versions and accessories, all of which have been independently tested and certified by Eurovent. Designed around 5 different versions, the extensive range includes wall and ceiling mounted units, exposed or concealed with centrifugal fan, delivering one of the most versatile ranges of fan coils on the market today. All fan coils with centrifugal fans are equipped with electric motors which dramatically reduce electrical consumption of up to 40% comparative to previous models, with 6 speed motors as standard offering greater flexibility in the selection of products. New market trends have also led to an extension of the four pipe model which now has a two row LTHW coil giving improved outputs at lower flow and return temperatures. A full range of adjustment and control devices is available including the FREE innovative patented wireless system, for rapidly obtaining correct environmental temperature and with an investment proportional to performances, comfort and desired measurement precision. The model is complemented with a full range of accessories: various types of adjustment valves, sturdy support feet, rear covering panel for glass installation, additional electric heater, auxiliary condensate pump, fresh air intake louver, air inlet/outlet diffusers for fitted installations. Johnson Controls take part to the Eurovent program of fan coil performance certification.

29 Accessories for Balancing valves independent from the system pressure The balancing valve and a combined way valve allow the regulation of the water flow value autonomously, regardless of the system pressure, and the control of the flow by using an ON/OFF electrothermal actuator. The balancing valve allows you to balance the hydraulic system by supplying the required water flow, 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 flow rate value and also allows direct reading of the set value. alve operation logic p is the valve inlet pressure. p3 is the outlet pressure. p is the diaphragm activation pressure, which allows differential pressure p p3 to be maintained at a constant value, in order to guarantee the water to flow at the set value. The minimum differential pressure p p3, required to guarantee the correct value of the set water flow rate, is indicated in the diagrams on page 30. This is an essential factor to size the system pressure drop and pump pressure head. The flow 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 30. The following diagram shows an example of the flow rate trend according to the pressure drop and calibration required. Example DN 0 LEGEND: = Water flow rate Pd = Min. differential pressure p p3 (bar) Q = Area with inconstant water flow Q = Area with constant water flow S = Position of the adjustment valve plunger M = Position of the knob 9

30 Accessories for The valve upstreamdownstream minimum differential pressure ( p p3 ), which depends on the valve calibration value, must be exceeded to access the constant flow rate field. DN 0 DN 5 DN 0 LEGEND: Pd = Min. differential pressure p p3 (bar) E.g., when sizing the system pump, in which the DN 0 valves will be installed and in which 0 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 or 4 pipe devices. Preregulation 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 flow rate set even with partial loads. Preregulation can be blocked and leaded with the locking ring.

50 Free wireless control system Free Free is an innovative, fully wireless, electronic system for use with fan coil units, based on radio communication. This technology provides installation flexibility and a more accurate measurement of the room temperature. The probe can be moved until the most suitable position is found, without the worry of changes in the room layout and of its furniture and also without mounting it on a wall. f 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 is a result of the possibility to position the probe near the user location: this enables to keep the temperature exactly at the required value with energy savings compared with a traditional measurement system. Transmission is based on communication protocol EE80.5.4, the most suitable way to transmit a relatively low amount 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 its sale has been authorized in all the EU and EFTA countries. Main components Free includes 3 main components: A remote control which features a button panel and LCD display and can be wallmounted or positioned on a dedicated table support. t enables the control of all the operating variables of the fan coil units in different configurations.

55 Controls and units MB version A group of units with MB electronic board can be connected via a serial link and can consequently be managed at the same time by just one JTMB control or RT03 infrared remote control. Using the special jumper present on the MB board, one unit must be configured as the master, and all the others as slaves. t is clear that the remote control must be pointed at the receiver on the master unit. To avoid problems, it is recommended to install and connect the receiver only on the master unit.

56 Controls and units MB version PSMD multifunction control panel Description Multifunction control (to be used with MB board only) dentification PSMD 3093 Another option available for the serial communication between the units is the possibility to connect up to 60 units in series and manage them with just one wall mounted PSMD controller. The wall mounted controller can be used to set the operating mode for each individual unit connected, display the operating conditions of each individual unit, and set the ON/OFF time sets for each day of the week (the program can be set for all the units and for a maximum of two groups of units). f more than 60 units need to be connected, two or more controllers must be used. Each unit must have a MB board. The PSMD control is used to manage a series of fan coils, up to a maximum of 60 units (the maximum length of the RS 485 connection cable must not exceed 800 m), from one single control point. The PSMD control communicates via a serial line with all the units connected, with the possibility of controlling them all together or individually. n fact, the unique address of each individual fan coil means that all the units can be 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 PSMD panel can also be used for the time management of the units over the week. Four ON times and four OFF times can be set on the units for each day of the week. A different Temperature set that will be considered as Operation set for all connected appliances, can be set for each event. f the Temperature set is not entered for the individual 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 only from the PSMD wall mounted panel; while the latter can receive information from both the wall mounted panel (PSMD) and infrared remote control. Use the infrared 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 PSMD panel during execution of successive startup program. The PSMD panel cannot be used together 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. 56

57 Management system for a network of fan coils NET program for managing a network of MB fan coils Description Hardware/software supervisory system (to be used with MB board only) dentification NET NET is a centralised control system for networks of MB fan coils, based on software that runs on LNUX operating system (the program is provided preinstalled on a PC). The NET software offers a practical and economical solution for 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 access the historical operating data for each individual unit connected. The program exploits all the potential of our units with remote controls, representing an addition to the latter. The NET program is a control tool that can be used as a replacement for the remote control, or in parallel, however the settings made using NET can have priority over those made using the remote 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. The main program screen can display and interact with the entire network of units. An individual unit, a group of units or the entire network can be called so as to make modifications to the operating mode and the set point.
