ESTRO BLDC

1 GENERALITIES

Backed by thirty years of experience in the manufacture of fan coil units Galletti introduces the new ESTRO BLDC line. Galletti fan coils can be equipped with a permanent magnet (brushless) electric motor, controlled by an inverter, which enables continuous adjustment in the number of fan revolutions. The great advantage of brushless motors is the significant reduction in power consumption, which in instant operations reaches up to a

/3 of that of conventional motors and at around 50% in integrated operations, with the corresponding reduction in CO

emissions! The DC Inverter technology allows to continuously adjust the air flow 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 also the reduction in the noise emission of the fan coil, which is now proportional to the demands of the environment.

THE CONTROL

The operation of the unit with brushless motor is managed by the MYCOMFORT LARGE control panel, using an analogue output (0-10V) which is connected to the inverter.

The Galletti brushless fan coil thus represent the state of the art due to the possibility of regulating the operation, depending on the temperature of the air, its relative humidity, the temperature of the water and based on the programmable time slots. By means of the digital outputs it is possible to switch on and off external units or devices such as chiller, boiler, pumps, water circulation pumps, etc. Another analog output makes it possible to control the modulating valves.

Permanent magnets electric motor, mounted on vibration damping couplings, complete with winding thermal protection. The unit is equipped with an inverter board to control the motor, which can be used separately or installed on the motor itself (features below). By means dipswitches this system makes it possible to precisely set the maximum rotation speed of the motor (the control signal range being always 0-10 V) even when the maximum rotation speed must be controlled to reduce noise levels. The control inverter is equipped with Hall cells to precisely control the position of the rotor, and thus the rotation even at very low rotation speed (when traditional motors cannot be controlled). For the ESTRO BLDC project we selected top quality materials which, together with the great care and attention dedicated to the assembly of the main constructive components, make the new Galletti fan coil units highly reliable from a performance standpoint while minimising noise levels.

New construction concept unifying the ver tical and horizontal mounted models:

F L I Suspended wall installation, with cabinet, with vertical air flow. F A I Wall-mounted, with cabinet, with inclined air flow. F U I Floor or ceiling mounted, with cabinet, with vertical air flow and air

intake grille complete with filters.

F P I Ceiling mounted, cabinet with air outlet grilles and rear air intake with

filter.

F C I Vertical or horizontal recess mounted with heat insulated galvanised

sheet casing.

F F I Vertical and horizontal recess mounted, with front air intake, with

heat insulated galvanised sheet casing.

The performance features of Galletti ESTRO BLDC products are cer tified by EUROVENT which guarantees the reliability of the data shown on this documentation.

11 INSTALLATION REQUIREMENTS

The fan coils should be installed in a position where the room can be cooled or heated evenly, on walls or ceilings able to withstand their weight. It is advisable to install any accessories on the standard unit prior to positioning the latter. For installation and use of accessories, please refer to the relative technical sheets. To guarantee the proper functioning of the unit and access for routine and extraordinary maintenance purposes, it is necessary to comply with the minimum installation clearance requirements (see "overall dimensions" section). In case of recess mounted units an access panel should be provided.

In order to avoid hot air stratification in rooms heated with ceiling mounted fan coils, it is recommended:

- not to exceed the "H" installation heights referred to the maximum operating speed as shown on the diagram;

- supply the units with moderately hot water (water inlet 50/60°C);

- provide the air intake from the lower part of the room, if possible.

Install any remote control panel in an easily accessible position allowing the user to set the functions while ensuring an accurate reading of the ambient temperature, if provided . You should avoid:

- positions directly exposed to sunlight;

- positions exposed to direct currents of warm or cold air;

- placing obstacles that impede an accurate temperature reading.

During wintertime periods of quiescence, drain water from the system, to prevent ice from forming. If anti-freeze solutions are used, check for their freezing point using the table below.

12 MAINTENANCE

ESTRO BLDC type fan coils do not have particular maintenance requirements: it is sufficient to periodically clean the air filter. The motor requires no maintenance since it has self-lubricating bearings. It is recommended to replace the air filter once a year, using an original replacement filter; the fan coil unit model is specified on the identification plate on the inside of the side panel. Always consult the "Installation, use and maintenance manual" provided with the unit when undertaking maintenance and cleaning.
