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 EXCHANGER

Uprated 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 ASSEMBLY

All 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 ASSEMBLY

Tangential 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 SYSTEM

The 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 temperaturereading and definition ofminimum 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

- Operatingmode(cooling-dehumidification-ventilation-heating-automatic)

- Ventilation (automatic-maximum-medium-minimum)

- Switching on and off via Timer

- Air outlet flap sweep

- Clock

When, 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 FILTER

The 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.

7 WIRING DIAGRAMS

Make the electrical connections with the power supply disconnected, in accordance with current safety regulations.

Check that the mains electricity supply is compatible with the voltage shown on the unit rating plate.

Each fan coil requires an individual electric socket and a switch with a suitable safety fuse.

--------- Factory wiring

- - - - - Field wiring

Each fan coil requires an omnipolar main switch classified as overvoltage category III to be mounted on the power supply line.
