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 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

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.
