Unit description
This series of air-water heat pumps satises the heating, coo-
ling and domestic hot water production requirements of autonomous or centralized residential plants of medium and large 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 control system allows to manage not only the refrigerant
circuit but the whole plant with the possibility to choose different
solutions both for the heating and cooling plant and for the domestic hot water management. The possibility of solar panels or
other heating sources integration is also available.
The heating function optimizes the ow water temperature according both to the ambient temperature and to the outdoor temperature through climatic curves adaptable to the building features. It’s possible to manage a storage tank and two independent
circuits (a direct one and a mixed one).
The domestic hot water management allows to control the three way valve, the storage tank and the anti-legionella cycles (if
necessary).
The cooling function can be realized through “active cooling”
(refrigerant circuit inversion). When the unit is used in radiant
oor plants, to avoid condensate generation, a room humidity
sensor can be installed. During cooling mode operation a part of
the heating power in excess can be recovered for the domestic
hot water production (VD version).
The internal programmer clock allows to dene different daily
switching programs for heating, cooling and domestic hot water
production.
The refrigerant circuit, contained in a box repaired from the air
ow to simplify the maintenance operations, is equipped with
two scroll compressors mounted on damper supports, brazed
plate heat exchangers, electronic expansion valve, reverse
cycle valve, centrifugal fans (plug fans), nned coil realized with
copper pipes and alluminium ns. The circuit is protected by high
and low pressure switches and ow switches on the plate heat
exchanger.
The compressors are arranged in tandem on a single refrigerant
circuit and allow the capacity modulation according to the plant
requests in order to guarantee a high seasonal efficiency.
The plate heat exchanger and all the hydraulic pipes are thermally insulated in order to avoid condensate generation and reduce thermal losses.
The plug fans with electronic control of the rotational speed guarantee high efficiencies and low noise in all the operating conditions and allow to install the unit indoor (with ducted air inlet and
outlet). It is moreover possible to reduce the noise level during
the night.
All the units are provided with a phase sequence and correct
sequence controller device and with an outdoor temperature
sensor in order to realize the climatic control.
All the units are accurately built and individually tested in the
factory. Only electric and hydraulic connections are required for
installation.

GENERAL FEATURES
External structure. Basement, supporting structure and lateral
panels are made of galvanized and painted sheet-steel to
guarantee good resistance to atmospheric agents. Accessibility
to internal parts is possible removing the frontal and lateral
panels. For extraordinary manteinances also the other panels
can be removed.
Refrigerant circuit. It is contained inside a compartment
separated from the air flow to simplify maintenance and control
operations.
The scroll compressors (1) are mounted on damper supports
and are protected against overtemperatures and overcurrents.
Each compressor 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.
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
flow switch that detects whatever water flow lack.
The source side heat exchanger (3) is a finned coil realized
with grooved copper pipes and hydrophilic aluminium fins with
waved profile to increase the heat exchange coefficient. A tray
is placed under the coil to collect the condensate generated in
heating mode.
The expansion device (4), an electronic expansion valve,
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, liquid receiver (7) to compensate the different refrigerant
charge required in heating and in cooling mode 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 expansion valve
upstream pressure). All the pipes of the refrigerant circuit are
properly insulated to avoid condensate generation and minimize
thermal losses.
The plug fans (8) are equipped with an high efficiency
electronically commutated (EC) motor and guarantee enough
available static pressure to allow the indoor ducted installation
besides high efficiencies in all the operating conditions.
Hydraulic circuit. All the pipes are thermally insulated to avoid
condensate generation and minimize thermal losses. The circuit
can be equipped with a standard, high head or modulating
circulation pump (option). The circuit is always equipped also
with expansion vessel, safety valve and air vents.
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, to be placed indoor, allows to view and to
modify, if necessary, all the parameters of the unit.
All the units are supplied with an outdoor temperature sensor,
to be installed outside, in order to realize the climatic control.

GENERAL FEATURES
The microprocessor controller is able to manage not only the
unit itself but also all that components of the plant which allow to
realize a complete system.
The main functions of the control system are :
- room temperature control according to the outdoor temperature (climatic control)
- domestic hot water production (management of 3 way valve,
storage tank, anti legionella cycles…)
- management of a heating and/or cooling mixed circuit (pump
and 3 way mixing valve)
- management of a heating direct circuit (only pump)
- management of a storage tank for heating and/or cooling
- management of electrical heaters for heating and domestic
hot water (3 steps logic)
- solar panels integration
- room humidity control for cooling with radiant systems
- internal programmer clock (for heating, cooling and domestic
hot water)
- digital input for electrical energy low tariff
- alarm memory management and diagnostic
- compressor and pump operating hour counter
- possibility to manage more units in cascade (maximum 16)
Besides the user interface of the unit to be placed indoor, wired or wireless remote thermostats are available which allow to
control all the operating parameters of the unit and to acquire
the temperature in the different zones in order to realize a more
precise and comfortable control.
The unit controller is able to manage a lot of different plant solutions enabling automatically the necessary control algorythms
according to the components which have been connected. The
management of such components is possible through additional
expansion modules which communicate with the unit by means
of an internal bus and provide all the inputs and outputs required
to fulfil a complete system.
Room temperature
20.5 C
18:28
The controller is able to manage up to two zones in heating
(one by means of a mixed circuit and the other by means of a
direct circuit) and one zone in cooling (by means of a mixed
circuit).
It’s possible to realize more complex plants connecting to the
heat pump controller further expansion modules in order to
extend without limits the number of zones to be managed.
For each zone the following parameters can be set :
- set point
- daily or weekly operating time table
- climatic control curve
- room control sensor : it can be in common with the other
zones or independent (in that case it’s necessary to install
an additional room thermostat)

Available static head
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 as lower as possible.
The rotational speed of the fans can be increased compared to the factory setting in order to increase the available static head up to the
maximum available value reported in the table.
