medium size.
All the units are suitable for indoor installation and can be applied to fan coil plants, radiant oor plants and high efciency
radiators plants.
The refrigerant circuit, contained in a compartment protected
from the air ow to simplify the maintenance operations, is
equipped with scroll compressor mounted on damper supports,
brazed plate heat exchanger, thermostatic expansion valve, reverse cycle valve, centrifugal fans (plug fan), nned coil made of
copper pipes and aluminium louvered ns. The circuit is protected by high and low pressure switches and differential pressure
switch on the plate heat exchanger.
The plate heat exchanger and all the hydraulic pipes are thermally insulated in order to avoid condensate generation and to
reduce thermal losses.
All the units are equipped with variable speed fans control that
allows the units to operate with low outdoor temperatures in cooling and high outdoor temperature in heating and permits to
reduce noise emissions in such operating conditions.
The low noise acoustic setting up (AS) is obtained, starting from
the base setting up (AB), reducing the rotational speed of the
fans and mounting sound jackets on the compressors.
All the units are supplied with an outdoor temperature sensor, already installed on the unit, in order to realize the climatic control.
All the units are provided with a phase presence and correct
sequence controller device.
All the units are accurately built and individually tested in the
factory. Only electric and hydraulic connections are required for
installation.

GENERAL FEATURES
Description of components
External structure. Basement, supporting structure and lateral
panels are made of galvanized and painted sheet-steel (colour
RAL 7035) to guarantee good resistance to atmospheric agents.
Accessibility to internal parts is possible removing the frontal
panel. For extraordinary manteinances also the rear panel can
be removed.
Refrigerant circuit. It is contained inside a compartment
separated from the air flow to simplify maintenance and control
operations.
The hermetic scroll compressor (1) is mounted on damper
supports and is protected against overtemperatures and
overcurrents. It is equipped with an electrcal heater, that is
activated when the compressor turns off, to keep the compressor
crankcase oil temperature high enough to prevent migration of
the refrigerant during winter stops and to evaporate any liquid
present in the crankcase, in order to prevent possible liquid
rushes on starting (only heat pump models).
The plant side heat exchanger (2) is a brazed stainless steel
plate heat exchanger, properly insulated to avoid condensate
generation and to minimize thermal losses, and protected by a
differential pressure switch that detects whatever water flow lack.
It is moreover protected against freeze danger by an antifreeze
electrical heater.
The source side heat exchanger (3) is a finned coil realized with
grooved copper pipes and aluminium fins with notched profile to
increase the heat exchange coefficient. A tray is obtained in the
basement to collect the condensate generated in heating mode.
The expansion device (4), a thermostatic expansion valve with
external equalizer, allows the unit to adjust itself to the different
operating conditions keeping steady the set superheating.
The refrigerant circuit of each unit contains moreover solid
core hermetic filter dryer (5) to restrain impurity and moisture
residuals that could be present in the circuit, high and low
pressure switches in order to assure the compressor to
operate inside the permitted limits, 4 way reverse cycle valve
(6) to allow operating mode change reversing the refrigerant flow
(only heat pump models), liquid receiver (7) to compensate the
different refrigerant charge required in heating and in cooling
mode (only heat pump models) and pressure connections
SAE 5/16” - UNF 1/2” - 20 equipped with pin, gasket and
blind nut, as required for the use of R410A refrigerant (they
allow the complete check of the refrigerant circuit: compressor
inlet pressure, compressor outlet pressure and thermostatic
expansion valve upstream pressure).
The fans (8) are plug fan type fans equipped with EC direct
current motor and embedded inverter. The fans rotational speed
is modulated continuosly to control the condensation pressure
(in cooling) and the evaporation pressure (in heating) in order to
optimize the operating conditions of the unit and to reduce noise
emissions. The maximum rotational speed can be modified by
parameter in order to set the available static head of the fan to
the plant requirements.
Hydraulic circuit. All the pipes are thermally insulated to avoid
condensate generation and minimize thermal losses. The circuit
can be equipped with different kind of circulation pump (option).
In that case the circuit is also equipped with expansion vessel
and air vents. It is also possible to integrate inside the unit a buffer
tank arranged as buffer on the flow towards the plant (option). In
that case the circuit is equipped not only with expansion vessel
and air vents, but also with safety valve, automatic air vent and
drain cock.
Electrical panel. It contains all the power, control and security
components necessary to guarantee the unit to work properly.
The unit is managed by a microprocessor controller to which all
the electrical loads and the control devices are connected. The
user interface, placed on the frontal panel, allows to view and to
modify, if necessary, all the parameters of the unit.
All the units are supplied with an outdoor temperature sensor,
already installed on the unit, in order to realize the climatic
control.

GENERAL FEATURES
Control system
The unit is managed by a microprocessor controller to which,
through a wiring board, all the electrical loads and the control
devices are connected. The user interface is realized by a
display and four buttons that allow to view and, if necessary,
modify all the operating parameters of the unit. It's available, as
an accessory, a remote control that reports all the functionalities
of the user interface placed on the unit.
The main functions available are :
- water temperature management (through set point
adjustment)
- adaptive function
- climatic control in heating and in cooling mode (automatic set
point adjustment according to outdoor air temperature)
- dynamic defrost cycle management according to outdoor air
temperature
- alarm memory management and diagnostic
- fans management by means of continuous rotational speed
control
- pump management
- integrative electrical heaters management in heating mode
(2 step logic)
- compressor and pump operating hours recording
- serial communication through Modbus protocol
- remote stand by
- remote cooling-heating
- general alarm digital output
Versions
Each model can be supplied in three different versions to satisfy the application requirements of the plants. The unit is always
supplied assembled, wired and factory tested.
The version is automatically identified by the option "Storing and pumping module" selected.
Base Version - VB
The unit does not contain neither
circulating pump nor tank. Therefore
a proper water flow through the plate
heat exchanger must be guaranteed to
prevent internal safety devices activation.
In any case the pump, if properly sized,
can be connected to the electrical panel
of the unit and managed by the controller
of the unit.
Pump Version - VP
The unit contains a circulating pump, air
vents, expansion vessel and drain cock.
Tank Version - VA
The unit contains a tank (arranged as
buffer on the flow towards the plant),
safety valve, circulating pump, air vents,
expansion vessel and drain cock.
The tank is also arranged for the
installation of antifreeze or integrative
electrical heaters.

In case of ducted installation the total pressure drops in the inlet and outlet ducts can not exceed the maximum available static head.
The minimum duct section must guarantee that the medium air velocity does not exceed 2,5 m/s in order to avoid noise problems and
to keep the pressure drops lower as possible.
