2.4 Air filters

60% (M5) panel filters in return air and ePM
1
55% (F7) rigid bag filters in fresh air. Both types of filters are mounted on
slides equipped with gaskets to ensure effective sealing. Their position, upstream of the internal components, also guarantees
their protection.
2.5 Fans
The units are equipped with high efficiency plug-fan type fans with built-in brushless EC motor. In this way it is possible to
guarantee an accurate regulation of the airflow both in the supply and extract section, ensuring that all regulatory requirements
such as SFP are met with. The airflow rate of the fan is managed through the integrated electronic control system thus
ensuring, according to the needs of the system, that the correct operation of the unit is maintained with consequent saving
of the energy absorbed by the unit.
The fans are fixed to the frame by means of selfcentering brackets to ensure the correct distance between the impeller and
the nozzle, thus optimizing performance.
2.6 Test
Units are fully assembled and wired at the factory and subjected to a complete functional test before shipment. They are
manufactured in compliance with the safety standard of the Machinery Directive 2006/42/EC, the Low Voltage Directive
2006/95/EC, and the Electromagnetic Compatibility Directive 2004/108/EC and therefore complies with the "Health and
safety requirements" prescribed. Units are provided with CE markings, certificate of conformity, user and maintenance
manual.
2.7 Packing
Units are supplied on thick wooden feet and wrapped in plastic film to protect against impacts during transport and handling
on site.
3. VERSIONS
3.1 Version ECO
ECO: complete with air temperature sensors installed on the fresh air intake and on room return air. The control allows to
select, in stepless mode, the supply and return fan speeds, summer/winter seasonal change over, and programming for daily
time zones. An optional hot water or cold water coil may also be managed, controlled by a 3-way modulating valve through
the room return air sensor.
The optional electric post-heating coil is also managed in modulating mode (always via the room return air sensor). The
control alerts the user when filters need replacing (the clogged state of the filters is monitored by a pair of differential
pressure switches supplied as standard) or the onset of any alarm; this may also be integrated into modern home automation
systems via RS485 serial port with Modbus protocol.
3.2 Version PLUS
PLUS: this control option is set to operate at constant pressure, it is supplied complete with pressure transducer and air
temperature sensors installed on the fresh air intake and room return air.
The control system allows to select, in stepless mode, the supply and return fan speeds.
It also manages the summer/winter seasonal change over and programming for daily time zones.
The control can also manage an optional hot water or cold water coil through a 3-way modulating valve and an additional
supply air sensor in order to maintain a fixed point operating logic.
The same logic can also be used to manage an electric post-heating coil, if present. The control alerts the user when filters
need replacing (the clogged state of the filters is monitored by a pair of differential pressure switches supplied as standard) or
the onset of any alarm; this may also be integrated into modern home automation systems via RS485 serial port with Modbus
protocol.
