This series of water-water heat pumps satises the heating,
cooling and domestic hot water production requirements of au-
tonomous or centralized residential plants of medium and large
size.
All the units are suitable for indoor installation and can be ap-
plied to fan coil plants, radiant oor plants and high efciency
radiators plants.
As source both water (from well, river, lake…) or brine solutions
(from geothermic probes) can be used.
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 do-
mestic hot water management. The possibility of solar panels or
other heating sources integration is also available.
The heating function optimizes the ow water temperature ac-
cording both to the ambient temperature and to the outdoor tem-
perature through climatic curves adaptable to the building featu-
res. 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 th-
ree way valve, the storage tank and the anti-legionella cycles (if
necessary).
The cooling function can be realized through “passive cooling”
(free cooling), through “active cooling” (refrigerant circuit inver-
sion) or through both systems actuated in sequence. When the
unit is used in radiant oor plants, to avoid condensate gene-
ration, 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 dene different daily
switching programs for heating, cooling and domestic hot water
production.
The refrigerant circuit is equipped with scroll compressor
mounted on damper supports, brazed plate heat exchangers,
electronic expansion valve and reverse cycle valve (for rever-
sible units). The circuit is protected by high and low pressure
switches and ow switches on both the exchangers.
In the low noise setting up units (AS) the outdoor structure is
thermally and acoustically insulated in order to reduce sound
propagation and to allow the installation in domestic places.
All the hydraulic pipes are thermally insulated to avoid conden-
sate generation.
All the units are supplied with phase sequence and voltage con-
troller 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
Description of components
External structure. Basement, supporting structure and 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 rear panel can be removed.
In the units with low noise acoustic setting up the basement, the
supporting structure and the panels are completely insulated in
order to minimize noise emissions in the surroundings.
Refrigerant circuit. It is contained inside a compartment easily
accessible to simplify maintenance and control operations.
The hermetic scroll compressor (1) is mounted on damper
supports and is protected against overtemperatures and
overcurrents.
The heat exchangers on the plant side (2) and on the source
side (3) are realized with brazed stainless steel plates, properly
insulated to avoid condensate generation and to minimize thermal
losses, and protected by a flow switch that detects whatever water
flow lack. 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 (only for reversible heat
pumps), 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, thermostatic expansion valve upstream pressure and
pressure drops accross the filter). All the pipes of the refrigerant
circuit are properly insulated to avoid condensate generation
and to minimize thermal losses.
Hydraulic circuit. Both the hydraulic circuits on the plant side
and on the source side are equipped with expansion vessel, air
vents and drain valves. The circuit on the plant side is moreover
equipped with pressure safety valve. All the pipes are thermally
insulated to avoid condensate generation and minimize thermal
losses. The circuit on the plant side can be equipped with a
circulation pump (option) while the circuit on the source side can
be equipped with a circulation pump (option) or with a two way
valve (option).
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 part of the unit, 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
Control system
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
- passive cooling
- 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 standard user interface present on all the units,
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 ad-
ditional expansion modules which communicate with the unit by
means of an internal bus and provide all the inputs and outputs
required to full a complete system.
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)
