1 GENERALITIES

High wall-mounted FM fan coil units are available in 3 models with cooling capacities ranging from 2.1 to 4.4 kW, complete with electronically controlled inverter motor (BLDC, 2 or 3-way ON/OFF solenoid valve and infrared remote control.

The performance features of FM fan coil units are certified by EUROVENT which guarantees the reliability of the data shown on this documentation.

2 CONSTRUCTIVE FEATURES

CABINET

The ABS cabinet features attractive design, rounded shape, for every type of environment.The integrated air outlet is equipped with a motor driven flap that can sweep automatically or be positioned manually, and adjustable fins for a uniform distribution of air in the room.

The front panel is complete with display to show all the functions of the unit and the room temperature.

HEAT EXCHANGERUprated heat exchanger made with copper piping and high efficiency alumi-nium fins with hydrophilic surface treatment, complete with air vent valve and facilitated emptying valve.

ON/OFF SOLENOID VALVE ASSEMBLYAll units are equipped with 2 or 3-way solenoid valve with electrothermal ON/OFF actuator (230 V) directly installed on the heat exchanger inside the unit and controlled by the microprocessor controller. Hoses for the connection to the system facilitate the installation operations.

DECLARATION OF CONFORMITY

Galletti S.p.A. hereby declares, under its sole responsibility, that the high wall-mounted fan coil units belonging to the FM series, have been designed, built and tested in conformity with the specifications of European Directives: 2006/42/CE, 2004/108/CE, 2006/95/CE

2 CONSTRUCTIVE FEATURES

FAN-DRIVE ASSEMBLYTangential fan directly coupled to an electronically controlled electric motor of synchronous brushless type (BLDC) controlled by inverter.The great advantage of brushless motors is the significant reduction in power consumption, which reaches up to a 2/3 of that of asynchronous motors with the corresponding reduction in CO2 emissions. The DC Inverter technology allows to continuously adjust the air flow and heating capacity to the actual needs of the environment by considerably reducing the fluctuations in room temperature that are typical of step-by-step adjustments.

The direct consequence is the reduction in the noise emission of the fan coil, which is proportional to the demands of the environment.

CONTROL SYSTEMThe microprocessor control system with infrared user interface enables the automatic control of the fan coil unit.The main control specifications are:- Selection of the cooling, heating, dehumidification mode or the automatic

mode.- PID control algorithm to regulate the BLDC fan: the control logic adapts

the fan rpm to the difference between measured temperature and set temperature, integrate over time the deviation measured and adapt the rpm accordingly. The derivative logic analyzes the change speed thus assuring little variations.

- Water temperature reading and definition of minimum working temperatures - Auxiliary contacts for signalling of heating or cooling mode- Inlet contact for remote on/off operation ( (for instance signalling of room

occupied)- Serial port for the implementation of master/slave networks - Autorestart after power cut.

REMOTE CONTROL

Infrared remote control with LCD display, to set all the functions of the fan coil:- Switching on and off- Temperature Set point- Operating mode (cooling-dehumidification-ventilation-heating-automatic)- Ventilation (automatic-maximum-medium-minimum)- Switching on and off via Timer- Air outlet flap sweep- ClockWhen, in a maser/slave system, the fan coil with remote control is the master unit, the settings are automatically sent to the slave units.The flap sweep function is not applicable.

AIR FILTERThe filter is washable and can be easily removed for cleaning operations, by lifting the front panel of the cabinet.

3 ACCESSORIES

available as an option is a wired wallpad with a large display, which can be used to control and set all the functions of each individual fan coil unit in master/slave systems. WALLPAD supplied with cable for the connection to the fan coil unit.

8 MASTER / SLAVE NETWORKS

The FM fan coil units are equipped with a PCB suitable for the implementation of master/slave networks with up to 32 units. Depending on the control panel used on the master unit it is possible to implement two different types of master/slave control.

Global control communicationMaster unit with IR remote control or a wired WALLPAD.The master unit will transmit the settings to all slave units. During normal operation the slave units can receive data from the wireless remote control or the wall-mounted control. After receiving the global commands from the master unit, all slave unit settings will be replaced by the master settings. In case of global control communication it is not possible to set different settings on slave units, which will all work in the same manner.

Addressable communicationsThe master controller must be a wired wallpad. The slave unit parameters are set as usual. After receiving the control commands from the master unit, the addressed slave unit settings will be replaced by the master settingsIn that case using the WALLPAD it is possible to send customized instructions to each of the units connected to the network.

Master unit function The master unit sends the data referring to its settings to the slave unit. The settings of the Master unit are: Unit On / Off, Mode, Fan Speed , Timer, Clock, Temperature selection, sweep function and sleep function for use from remote control. The settings of the Master unit are: Unit On / Off, Mode, Fan Speed , Timer, Clock, Temperature selection, sweep function and sleep function for use from wall-mounted control.

8 MASTER / SLAVE NETWORKS

Slave unit function The slave unit receives data referring to its settings from the master unit. The slave unit can be set locally on a desired setting by means of the local controller, provided there are no subsequent changes to the settings of the master unit. The slave units can be set individually for switching on and off via the timer using the remote control or the wall-mounted control. The remote control cannot change the clock and timer settings set via the wall-mounted control.

10 INSTALLATION REqUIREMENTS

Select the position of the high wall-mounted unit based on the following considerations: The air inlet and outlet front part must be free of obstructions. The air should flow freely. The wall the unit is mounted on must be sufficiently rigid so as not to resonate and produce noise. The position should permit easy access for installing the connecting water pipes and in a convenient place for drainage. Make sure that the opening on both sides of the fan coil unit is as shown in the following drawing. The position above the floor should be higher than eye level. Avoid positions directly exposed to sunlight.

Higher than eye level.

FM


10 INSTALLATION REqUIREMENTS

Clearance for maintenance and repairing is shown above ** All dimensions are in mm. The signal receiver on the unit must be kept as far away as possible from any source of high frequency emissions. Keep the unit away from fluorescent lamps which can affect the control system. To avoid electric or magnetic interference of the control system, make sure that the control cables are installed separately from 220-240 Vac electric cables. Where electromagnetic waves are present, use shielded cables for the sensors. Install a filter if harmful interferences are present in the power supply.

Filter

11 ROUTINE MAINTENANCE

The material must undergo maintenance in order to retain its characteristics over time. Lack of maintenance may have the effect of voiding the product warranty. We recommend cleaning it once a month, but the frequency depends on operating conditions. To remove the filter Open the grill by lifting it from the lower position indicated by the arrow. Remove the filter from the grille.Use a vacuum cleaner to remove dust. If dust is glued to the filter, remove it with clean or soapy water, rinse the filter with clean water and dry it. Put the filter back into its housing in the grill. Close the liftable grill by pressing both sides down, into the position indicated by the arrow.
